     feh -- image viewer and cataloguer

     feh [options] [files | directories	| URLs ...]

     This manual documents feh 2.18

     Compile-time switches: libcurl support enabled, Xinerama support enabled,
     builtin EXIF support disabled

     feh is a mode-based image viewer.	It is especially aimed at command line
     users who need a fast image viewer	without	huge GUI dependencies, though
     it	can also be started by (graphical) file	managers to view an image.  By
     default (unless arguments or a filelist are specified), feh displays all
     files in the current directory.

     feh supports filelists, various image sorting modes, image	captions, HTTP
     and more.	Configurable keyboard and mouse	shortcuts are used to control

     feh can also be used as wallpaper setter.

     EXIF tags are supported either using exiv2	/ exifgrep via --info (see the
     USAGE EXAMPLES section), or as a builtin feature by compiling feh with
     exif=1. In	this build of feh, builtin EXIF	support	is disabled.

     feh is based on various modes, which are selected at startup by command
     line options.

     Slideshow mode is the default.  It	opens a	window and displays the	first
     image in it; the slideshow	position can be	advanced (or otherwise
     changed) using keyboard and mouse shortcuts.  In slideshow	mode, images
     can be deleted either from	the filelist or	from the disk, a changed
     filelist can also be saved	to the disk and	reopened at a later time.  An
     image can also be read from stdin via "feh	-".

     Montage mode forms	a montage from the filelist.  The resulting image can
     be	viewed or saved, and its size can be limited by	height,	width or both.

     Index mode	forms an index print from the filelist.	 Image thumbnails are
     shown along with the filename, filesize and pixel size, printed using a
     truetype font of your choice.  The	resulting image	can be viewed or
     saved, and	its size can be	limited	by height, width or both.

     Thumbnail mode is like index mode,	but the	mini-images are	clickable and
     open the selected image in	a new window.

     Multiwindow mode shows images in multiple windows,	instead	of as a
     slideshow in one window.  Don't use with a	large filelist ;)

     List mode doesn't display images.	Instead, it outputs an ls-style	list-
     ing of the	files in the filelist, including image info such as size, num-
     ber of pixels, type, etc.	There is also a	Customlist mode	which prints
     image info	in a custom format specified by	a printf-like format string.

     feh can also list either all the loadable files in	a filelist or all the
     unloadable	files.	This is	useful for preening a directory.

     feh can open any format supported by Imlib2, most notably jpeg, png, pnm,
     tiff, and bmp. The	gif format is also supported, but only for static im-
     ages. In case of animations, only the first frame will be shown.  If the
     convert binary (supplied by ImageMagick) is available, it also has	lim-
     ited support for many other filetypes, such as svg, xcf and otf. Use
     --magick-timeout num with a non-negative value to enable it.

     -A, --action [flag][[title]]action
	     Specify a shell command as	an action to perform on	the image.  In
	     slideshow or multiwindow mode, the	action will be run when	the
	     action_0 key is pressed, in list mode, it will be run for each
	     file.  In loadable/unloadable mode, it will be run	for each load-
	     able/unloadable file, respectively.  In thumbnail mode, clicking
	     on	an image will cause the	action to run instead of opening the

	     If	flag is	";", feh will reload the current image instead of
	     switching to the next one (slideshow mode)	or closing the window
	     (multiwindow mode)	after executing	the action.  If	[title]	is
	     specified (note the literal "[" and "]"), --draw-actions will
	     display title instead of action in	the action list. Note that
	     title must	not start with a space.	If it does, the	action is han-
	     dled as if	it did not have	a title. This special case exists for
	     backwards compatibility reasons and makes sure that actions like
	     "[	-L %F ]	&& foo"	still work.

	     The action	will be	executed by /bin/sh.  Use format specifiers to
	     refer to image info, see FORMAT SPECIFIERS	for details.  Example
	     usage: "feh -A "mv	~/images/%N" *".

     --action1 .. --action9 [flag][[title]]action
	     Extra actions which can be	set and	triggered using	the appropri-
	     ate number	key.

	     (only if compiled with exif=1) Automatically rotate images	based
	     on	EXIF data. Does	not alter the image files.

     -Z, --auto-zoom
	     Zoom pictures to screen size in fullscreen	/ fixed	geometry mode.

     -x, --borderless
	     Create borderless windows.

     -P, --cache-thumbnails
	     Enable thumbnail caching in ~/.thumbnails.	 Only works with
	     thumbnails	<= 256x256 pixels.

     -K, --caption-path	path
	     Path to directory containing image	captions.  This	turns on cap-
	     tion viewing, and if captions are found in	path, which is rela-
	     tive to the directory of each image, they are overlayed on	the
	     displayed image.  E.g. with caption path "captions/", and viewing
	     image "images/foo.jpg", the caption will be looked	for in

     -L, --customlist format
	     Don't display images, print image info according to format	in-
	     stead.  See FORMAT	SPECIFIERS.

	     Exit feh after one	loop through the slideshow.

     -G, --draw-actions
	     Draw the defined actions and what they do at the top-left of the

	     (only if compiled with exif=1) display some EXIF information in
	     the bottom	left corner, similar to	using --info with exiv2	/ ex-
	     ifgrep .

     -d, --draw-filename
	     Draw the filename at the top-left of the image.

	     Show overlay texts	(as created by --draw-filename et al) on a
	     semi-transparent background to improve their readability

     -f, --filelist file
	     This option is similar to the playlists used by music software.
	     If	file exists, it	will be	read for a list	of files to load, in
	     the order they appear.  The format	is a list of image filenames,
	     absolute or relative to the current directory, one	filename per

	     If	file doesn't exist, it will be created from the	internal
	     filelist at the end of a viewing session.	This is	best used to
	     store the results of complex sorts	(-Spixels for example) for
	     later viewing.

	     Any changes to the	internal filelist (such	as deleting a file or
	     it	being pruned for being unloadable) will	be saved to file when
	     feh exits.	 You can add files to filelists	by specifying them on
	     the command line when also	specifying the list.

	     If	file is	"-", feh will read the filelist	from its standard in-

     -e, --font	font
	     Set global	font.  Should be a truetype font, resident in the cur-
	     rent directory or the font	directory, and should be defined in
	     the form fontname/points, like "myfont/12".

     -C, --fontpath path
	     Specify path as extra directory in	which to search	for fonts; can
	     be	used multiple times to add multiple paths.

	     Disable antialiasing for zooming, background setting etc.

     -I, --fullindex
	     Same as index mode, but with additional information below the
	     thumbnails.  Works	just like "feh --index --index-info
	     "%n\n%S\n%wx%h"".	Enables	MONTAGE	MODE OPTIONS.

	     Note: This	option needs to	load all images	to calculate the di-
	     mensions of the feh window, so when using it with many files it
	     will take a while before a	feh window is visible.	Use --preload
	     to	get a progress bar.

     -F, --fullscreen
	     Make the window fullscreen.  Note that in this mode, large	images
	     will always be scaled down	to fit the screen, --zoom zoom only
	     affects smaller images and	never scales larger than necessary to
	     fit the screen size. The only exception is	a zoom of 100, in
	     which case	images will always be shown at 100% zoom, no matter
	     their dimensions.

     -g, --geometry [width x height] [+	x + y]
	     Limit (and	don't change) the window size.	Takes an X-style geom-
	     etry string like 640x480 with optional +x+y window	offset.	 Note
	     that larger images	will be	zoomed out to fit, but you can see
	     them at 1:1 by clicking the zoom button.  Also note that this op-
	     tion does not enforce the geometry, changing it by	a tiling WM or
	     manually is still possible. After each resize, the	resulting win-
	     dow size is used as the new size limit.

     -Y, --hide-pointer
	     Hide the pointer (useful for slideshows).

     -B, --image-bg style
	     Use style as background for transparent image parts and the like.
	     Accepted values: checks, white, black.  The default for windowed
	     mode is checks, while fullscreen defaults to black.

     -i, --index
	     Enable Index mode.	 Index mode is similar to montage mode,	and
	     accepts the same options.	It creates an index print of thumb-
	     nails, printing the image name beneath each thumbnail.  Index
	     mode enables certain other	options, see INDEX MODE	OPTIONS	and

     --index-info format
	     Show image	information based on format below thumbnails in	index
	     / thumbnail mode.	See FORMAT SPECIFIERS.	May contain newlines.
	     Use "--index-info `'" to display thumbnails without any info text

	     Note: If you specify image-related	formats	(such as %w or %s),
	     feh needs to load all images to calculate the dimensions of its
	     own window.  So when using	them with many files, it will take a
	     while before a feh	window becomes visible.	 Use --preload to get
	     a progress	bar.

     --info [flag]commandline
	     Execute commandline and display its output	in the bottom left
	     corner of the image.  Can be used to display e.g. image dimen-
	     sions or EXIF information.	 Supports FORMAT SPECIFIERS.  If flag
	     is	set to ";", the	output will not	be displayed by	default, but
	     has to be enabled by the toggle_info key.

     -k, --keep-http
	     When viewing files	using HTTP, feh	normally deletes the local
	     copies after viewing, or, if caching, on exit.  This option pre-
	     vents this	so that	you get	to keep	the local copies.  They	will
	     be	in /tmp	with "feh" in the name.

	     When viewing files	with HTTPS, this option	disables strict	host-
	     name and peer checking. This allows images	on sites with self-
	     signed certificates to be opened, but is no more secure than
	     plain HTTP.

	     When switching images, keep zoom and viewport settings (zoom
	     level and X, Y offsets)

     -l, --list
	     Don't display images.  Analyze them and display an	ls(1) -	style
	     listing.  Useful in scripts to hunt out images of a certain
	     size/resolution/type etc.

     -U, --loadable
	     Don't display images.  Just print out their names if imlib2 can
	     successfully load them.  Returns false if at least	one image
	     failed to load.

     --magick-timeout timeout
	     Stop trying to convert unloadable files after timeout seconds. A
	     negative value disables covert / magick support altogether, a
	     value of zero causes feh to try indefinitely. By default, magick
	     support is	disabled.

     --max-dimension width x height
	     Only show images with width <= width and height <=	height.	 If
	     you only care about one parameter,	set the	other to 0 (or a
	     negative value).

     -M, --menu-font font
	     Use font (truetype, with size, like "yudit/12") as	menu font.

     --min-dimension width x height
	     Only show images with width >= width and height >=	height.	 If
	     you only care about one parameter,	set the	other to 0.

     -m, --montage
	     Enable montage mode.  Montage mode	creates	a new image consisting
	     of	a grid of thumbnails of	the images in the filelist.  When mon-
	     tage mode is selected, certain other options become available.

     -w, --multiwindow
	     Disable slideshow mode.  With this	setting, instead of opening
	     multiple files in slideshow mode, multiple	windows	will be
	     opened; one per file.

	     Don't jump	to the first image after resorting the filelist.

     -N, --no-menus
	     Don't load	or show	any menus.

	     By	default, window	sizes are limited to the screen	size.  With
	     this option, windows will have the	size of	the image inside them.
	     Note that they may	become very large this way, making them	unman-
	     ageable in	certain	window managers.

	     Disable Xinerama support.	Only makes sense when you have Xin-
	     erama support compiled in.

     -j, --output-dir directory
	     Save files	to directory (only useful with -k)

     -p, --preload
	     Preload images.  This doesn't mean	hold them in RAM, it means run
	     through them and eliminate	unloadable images first.  Otherwise
	     they will be removed as you flick through.	 This also analyses
	     the images	to get data for	use in sorting,	such as	pixel size,
	     type etc.	A preload run will be automatically performed if you
	     specify one of these sort modes.

     -q, --quiet
	     Don't report non-fatal errors for failed loads.  Verbose and
	     quiet modes are not mutually exclusive, the first controls	infor-
	     mational messages,	the second only	errors.

     -z, --randomize
	     When viewing multiple files in a slideshow, randomize the file
	     list before displaying. The list is re-randomized whenever	the
	     slideshow cycles (that is,	transitions from last to first image).

     -r, --recursive
	     Recursively expand	any directories	in the commandline arguments
	     to	the content of those directories, all the way down to the bot-
	     tom level.

	     Don't recursively expand any directories (enabled by default).
	     Useful to override	theme options.

     -R, --reload int
	     Reload filelist and current image after int seconds.  Useful for
	     viewing HTTP webcams or frequently	changing directories.  (Note
	     that the filelist reloading is still experimental.)

	     If	an image is removed, feh will either show the next one or
	     quit.  However, if	an image still exists, but can no longer be
	     loaded, feh will continue to try loading it.

     -n, --reverse
	     Reverse the sort order.  Use this to invert the order of the
	     filelist.	E.g. to	sort in	reverse	width order, use -nSwidth.

     -., --scale-down
	     Scale images to fit window	geometry (defaults to screen size when
	     no	geometry was specified). Note that the window geometry is not
	     updated when changing images at the moment. This option is	recom-
	     mended for	tiling window managers.	 This option is	ignored	when
	     in	fullscreen mode.

	     In	tiling environments, this also causes the image	to be centered
	     in	the window.

     --scroll-step count
	     Scroll count pixels whenever scroll_up, scroll_down, scroll_left
	     or	scroll_right is	pressed.  Note that this option	accepts	nega-
	     tive numbers in case you need to inverse the scroll direction;
	     see KEYS CONFIG SYNTAX to change it permanently.  Default:	20

     -D, --slideshow-delay float
	     For slideshow mode, wait float seconds between automatically
	     changing slides.  Useful for presentations.  Specify a negative
	     number to set the delay (which will then be float * (-1)),	but
	     start feh in paused mode.

     -S, --sort	sort_type
	     The file list may be sorted according to image parameters.	 Al-
	     lowed sort	types are: name, filename, dirname, mtime, width,
	     height, pixels, size, format.  For	sort modes other than name,
	     filename, dirname,	or mtime, a preload run	will be	necessary,
	     causing a delay proportional to the number	of images in the list.

	     The mtime sort mode sorts images by most recently modified. To
	     sort by oldest first, reverse the filelist	with --reverse.

     -|, --start-at filename
	     Start the filelist	at filename.  Note that	at the moment,
	     filename must match an (expanded) path in the filelist. So, if
	     the file to be matched is passed via an absolute path in the
	     filelist, filename	must be	an absolute path. If the file is
	     passed via	a relative path, filename must be an identical rela-
	     tive path.	This is	a known	issue.	See also USAGE EXAMPLES.

     -T, --theme theme
	     Load options from config file with	name theme - see THEMES	CONFIG
	     SYNTAX for	more info.  Note that commandline options always over-
	     ride theme	options.  The theme can	also be	set via	the program
	     name (e.g.	with symlinks),	so by default feh will look for	a
	     "feh" theme.

     -t, --thumbnails
	     Same as Index mode, but the thumbnails are	clickable image
	     launchers.	 Note that --fullscreen	and --scale-down do not	affect
	     the thumbnail window. They	do, however, work for image windows
	     launched from thumbnail mode.  Also supports MONTAGE MODE

     -~, --thumb-title string
	     Set title for windows opened from thumbnail mode.	See also

     -^, --title title
	     Set window	title.	Applies	to all windows except those opened
	     from thumbnail mode.  See FORMAT SPECIFIERS.

     -u, --unloadable
	     Don't display images.  Just print out their names if imlib2 can
	     NOT successfully load them.  Returns false	if at least one	image
	     was loadable.

     -V, --verbose
	     output useful information,	progress bars, etc.

     -v, --version
	     output version information	and exit.

     --xinerama-index screen
	     Override feh's idea of the	active Xinerama	screen.	May be useful
	     in	certain	circumstances where the	window manager places the feh
	     window on Xinerama	screen A while feh assumes that	it will	be
	     placed on screen B.

	     In	background setting mode: When used with	any option other than
	     --bg-tile:	Only set wallpaper on screen.  All other screens will
	     be	filled black/white.  This is most useful in a Xinerama config-
	     uration with overlapping screens.	For instance, assume you have
	     two overlapping displays (index 0 and 1), where index 0 is
	     smaller. To center	a background on	the display with index 0 and
	     fill the extra space on index 1 black/white, use
	     "--xinerama-index 0" when setting the wallpaper.

     --zoom percent | max | fill
	     Zoom images by percent when in full screen	mode or	when window
	     geometry is fixed.	 When combined with --auto-zoom, zooming will
	     be	limited	to the specified percent.  Specifying max is like set-
	     ting --auto-zoom, using fill makes	feh zoom the image like	the
	     --bg-fill mode.

     These additional options can be used for index, montage and (partially)
     thumbnail mode.

     -a, --alpha int
	     When drawing thumbnails onto the background, set their transpar-
	     ency level	to int (0 - 255).

     -b, --bg file | trans
	     Use file as background for	your montage.  With this option	speci-
	     fied, the montage size will default to the	size of	file if	no
	     size restrictions were specified.	Alternatively, if file is
	     "trans", the background will be made transparent.

     -X, --ignore-aspect
	     By	default, the montage thumbnails	will retain their aspect ra-
	     tios, while fitting into thumb-width/-height.  This options
	     forces them to be the size	set by --thumb-width and
	     --thumb-height.  This will	prevent	any empty space	in the final

     -H, --limit-height	pixels
	     Limit the height of the montage.

     -W, --limit-width pixels
	     Limit the width of	the montage, defaults to 800 pixels.

	     If	both --limit-width and --limit-height are specified, the mon-
	     tage will be exactly width	x height pixels	in dimensions.

     -o, --output file
	     Save the created montage to file.

     -O, --output-only file
	     Just save the created montage to file without displaying it.

     -s, --stretch
	     Normally, if an image is smaller than the specified thumbnail
	     size, it will not be enlarged.  If	this option is set, the	image
	     will be scaled up to fit the thumbnail size.  Aspect ratio	will
	     be	maintained unless --ignore-aspect is specified.

     -E, --thumb-height	pixels
	     Set thumbnail height.

     -y, --thumb-width pixels
	     Set thumbnail width.

     -J, --thumb-redraw	n
	     Only relevant for --thumbnails: Redraw thumbnail window every n
	     images.  In feh <=	1.5, the thumbnail image used to be redrawn
	     after every computed thumbnail (so, it updated immediately).
	     However, since the	redrawing takes	quite long (especially for
	     thumbnail mode on a large filelist), this turned out to be	a ma-
	     jor performance penalty.  As a workaround,	the thumbnail image is
	     redrawn every 10th	image now by default. Set n = 1	to get the old
	     behaviour,	n = 0 will only	redraw once all	thumbnails are loaded.

     -@, --title-font font
	     Set font to print a title on the index, if	no font	is specified,
	     no	title will be printed.

     feh can also be used as a background setter.  Unless you pass the
     --no-fehbg	option,	it will	write a	script to set the current background
     to	~/.fehbg.  So to have your background restored every time you start X,
     you can add "sh ~/.fehbg &" to your X startup script (such	as
     ~/.xinitrc).  As of feh 2.13, this	script is executable, so "~/.fehbg &"
     will work as well.

     For the --bg-center and --bg-max options, you can use the --geometry op-
     tion to specify an	offset from one	side of	the screen instead of center-
     ing the image.  Positive values will offset from the left/top side, nega-
     tive values from the bottom/right.	 +0 and	-0 are both valid and distinct

     Note that all options except --bg-tile support Xinerama.  For instance,
     if	you have multiple screens connected and	use e.g.  --bg-center, feh
     will center or appropriately offset the image on each screen.  You	may
     even specify more than one	file, in that case, the	first file is set on
     screen 0, the second on screen 1, and so on.

     Use --no-xinerama to treat	the whole X display as one screen when setting
     wallpapers. You may also use --xinerama-index to use feh as a background
     setter for	a specific screen.

	     Center the	file on	the background.	 If it is too small, it	will
	     be	surrounded by a	black border

	     Like --bg-scale, but preserves aspect ratio by zooming the	image
	     until it fits.  Either a horizontal or a vertical part of the im-
	     age will be cut off

	     Like --bg-fill, but scale the image to the	maximum	size that fits
	     the screen	with black borders on one side.

	     Fit the file into the background without repeating	it, cutting
	     off stuff or using	borders.  But the aspect ratio is not pre-
	     served either

     %h	     Image height

     %l	     Total number of files in filelist

     %L	     Temporary copy of filelist. Multiple uses of %L within the	same
	     format string will	return the same	copy.

     %m	     Current mode

     %n	     Image name

     %%	     A literal %

     feh has three config files: themes	for theme definitions, keys for	key
     bindings and buttons for mouse button bindings.  It will try to read them
     from $XDG_CONFIG_HOME/feh/, which (when XDG_CONFIG_HOME is	unset) de-
     faults to ~/.config/feh/.	If the files are not found in that directory,
     it	will also try /etc/feh/.

     All config	files treat lines starting with	a "#" character	as comments.
     Note that mid-line	comments are not supported.

     .config/feh/themes	allows the naming of option groups, called themes.

     It	takes entries of the form "theme options ...", where theme is the name
     of	the entry and options are the options which will be applied when the
     theme is used.  Note that the options are not parsed by any shell.	There-
     fore, filename expansion ("*.jpg" and similar) is not supported. Quoting
     with both single and double quotes	works, though.

     An	example	entry would be "imagemap -rVq --thumb-width 40 --thumb-height
     30	--index-info '%n\n%wx%h'".

     You can use this theme in two ways.  Either call "feh -Timagemap *.jpg",
     or	create a symbolic link to feh with the name of the theme you want it
     to	use.  For the example above, this would	be "ln -s `which feh `
     ~/bin/imagemap".  Now just	run "imagemap *.jpg" to	use these options.

     Note that you can split a theme over several lines	by placing a backslash
     at	the end	of an unfinished line.

     Command line options always override theme	options.

     .config/feh/keys defines key bindings.  It	has entries of the form
     "action [key1 [key2 [key3]]]".

     Each key is an X11	keysym name as shown by	xev(1),	like "Delete".	It may
     optionally	start with modifiers for things	like Control, in which case
     key looks like mod-keysym (for example "C-Delete" for Ctrl+Delete or
     "C-1-Delete" for Ctrl+Alt+Delete)

     Available modifiers are C for Control, S for Shift	and 1, 4 for Mod1 and
     Mod4.  To match an	uppercase letter like "S" instead of "s", the Shift
     modifier is not required.

     Specifying	an action without any keys unbinds it (i.e. the	default	bind-
     ings are removed).

     Note: Do not use the same keybinding for multiple actions.	When binding
     an	action to a new	key (or	mouse button), make sure to unbind it from its
     previous action, if present.  feh does not	check for conflicting bind-
     ings, so their behaviour is undefined.

     For a list	of the action names, see KEYS.

     In	an image window, the following keys may	be used	(The strings in
     [square brackets] are the config action names):

     a [toggle_actions]
	     Toggle actions display (see --draw-actions)

     A [toggle_aliasing]
	     Enable/Disable anti-aliasing

     c [toggle_caption]
	     Caption entry mode.  If --caption-path has	been specified,	then
	     this enables caption editing.  The	caption	at the bottom of the
	     screen will turn yellow and can be	edited.	 Hit return to confirm
	     and save the caption, or escape to	cancel editing.	 Note that you
	     can insert	an actual newline into the caption using

     d [toggle_filenames]
	     Toggle filename display (see --draw-filename)

     e [toggle_exif]
	     (only if compiled with exif=1) Toggle EXIF	tag display

     f [save_filelist]
	     Save the current filelist as "feh_PID_ID_filelist"

     h [toggle_pause]
	     Pause/Continue the	slideshow.  When it is paused, it will not au-
	     tomatically change	slides based on	--slideshow-delay.

     i [toggle_info]
	     Toggle info display (see --info)

     k [toggle_keep_vp]
	     Toggle zoom and viewport keeping. When enabled, feh will keep
	     zoom and X, Y offset when switching images.

     m [toggle_menu]
	     Show menu.	 Use the arrow keys and	return to select items,
	     <escape> to close the menu.

     n,	<Space>, <Right> [next_img]
	     Show next image. Selects the next image in	thumbnail mode.

     o [toggle_pointer]
	     Toggle pointer visibility

     p,	<Backspace>, <Left> [prev_img]
	     Show previous image. Selects the previous image in	thumbnail

     q,	<Escape> [quit]
	     Quit feh

     r [reload_image]
	     Reload current image.  Useful for webcams

     s [save_image]
	     Save the current image as "feh_PID_ID_FILENAME"

     v [toggle_fullscreen]
	     Toggle fullscreen

     w [size_to_image]
	     Change window size	to fit current image size (plus/minus zoom, if
	     set).  In scale-down and fixed-geometry mode, this	also updates
	     the window	size limits.

     x [close]
	     Close current window

     z [jump_random]
	     Jump to a random position in the current filelist

     [,	] [prev_dir, next_dir]
	     Jump to the first image of	the previous or	next sequence of im-
	     ages sharing a directory name in the current filelist.  Use
	     --sort dirname if you would like to ensure	that all images	in a
	     directory are grouped together.

     <,	> [orient_3, orient_1]
	     In	place editing -	rotate the image 90 degrees (counter)clock-
	     wise.  The	rotation is lossless, but may create artifacts in some
	     image corners when	used with JPEG images.	Rotating in the	re-
	     verse direction will make them go away.  See jpegtran(1) for more
	     about lossless JPEG rotation.  Note: feh assumes that this	fea-
	     ture is used to normalize image orientation. For JPEG images, it
	     will unconditionally set the EXIF orientation tag to 1 ("0,0 is
	     top left")	after every rotation. See jpegexiforient(1) for	de-
	     tails on how to change this flag.

     _ [flip]
	     In	place editing -	vertical flip

     | [mirror]
	     In	place editing -	horizontal flip

     0 .. 9 [action_0 .. action_9]
	     Execute the corresponding action (0 = --action, 1 = --action1

     <Return> [action_0]
	     Run the command defined by	--action

     <home> [jump_first]
	     Show first	image

     <end> [jump_last]
	     Show last image

     <page up> [jump_fwd]
	     Go	forward	~5% of the filelist

     <page down> [jump_back]
	     Go	backward ~5% of	the filelist

     + [reload_plus]
	     Increase reload delay by 1	second

     - [reload_minus]
	     Decrease reload delay by 1	second

     <delete> [remove]
	     Remove current file from filelist

     <CTRL+delete> [delete]
	     Remove current file from filelist and delete it

     <keypad left>, <Ctrl+Left>	[scroll_left]
	     Scroll to the left

     <keypad right>, <Ctrl+Right> [scroll_right]
	     Scroll to the right

     <keypad up>, <Ctrl+Up> [scroll_up]
	     Scroll up

     <keypad down>, <Ctrl+Down>	[scroll_down]
	     Scroll down.  Note	that the scroll	keys work without anti-alias-
	     ing for performance reasons, hit the render key after scrolling
	     to	antialias the image.

     <Alt+Left [scroll_left_page]>
	     Scroll to the left	by one page

     <Alt+Right	[scroll_right_page]>
	     Scroll to the right by one	page

     <Alt+Up [scroll_up_page]>
	     Scroll up by one page

     <Alt+Down [scroll_down_page]>
	     Scroll down by one	page

     R,	<keypad	begin> [render]
	     Antialias the image.  Opens the currently selected	image in
	     thumbnail mode.

     <keypad +>, <Up> [zoom_in]
	     Zoom in

     <keypad ->, <Down>	[zoom_out]
	     Zoom out

     *,	<keypad	*> [zoom_default]
	     Zoom to 100%

     /,	<keypad	/> [zoom_fit]
	     Zoom to fit the window size

     ! [zoom_fill]
	     Zoom to fill the window size like --bg-fill

     The following keys	bindings are used for the feh menu:

     <Escape> [menu_close]
	     Close the menu

     <Up> [menu_up]
	     Highlight previous	menu item

     <Down> [menu_down]
	     Highlight next menu item

     <Left> [menu_parent]
	     Highlight parent menu item

     <Right> [menu_child]
	     Highlight child menu item

     <Return>, <Space> [menu_select]
	     Select highlighted	menu item

     .config/feh/buttons.  This	works like the keys config file: the entries
     are of the	form "action [binding]".

     Each binding is a button number.  It may optionally start with modifiers
     for things	like Control, in which case binding looks like mod-button (for
     example C-1 for Ctrl + Left button).

     Note: Do not use the same button for multiple actions.  feh does not
     check for conflicting bindings, so	their behaviour	is undefined.  Either
     unbind the	unwanted action, or bind it to another unused button.  The or-
     der in which you bind / unbind does not matter, though.

     For the available modifiers, see KEYS CONFIGURATION SYNTAX.

     In	an image window, the following buttons may be used (The	strings	in
     [square brackets] are the config action names).  Additionally, all	ac-
     tions specified in	the KEYS section can also be bound to a	button.

     unbound [reload]
	     Reload current image

     1 <left mouse button> [pan]
	     pan the current image

     2 <middle mouse button> [zoom]
	     Zoom the current image

     3 <right mouse button> [toggle_menu]
	     Toggle menu

     4 <mousewheel down> [prev_img]
	     Show previous image

     5 <mousewheel up> [next_img]
	     Show next image

     Ctrl+1 [blur]
	     Blur current image

     Ctrl+2 [rotate]
	     Rotate current image

     unbound [zoom_in]
	     Zoom in

     unbound [zoom_out]
	     Zoom out

     Default Bindings: When viewing an image, mouse button 1 pans the image
     (moves it around) or, when	only clicked, moves to the next	image
     (slideshow	mode only).  Quick drags with less than	2px of movement	per
     axis will be treated as clicks to aid graphics tablet users.  Mouse but-
     ton 2 zooms (click	and drag left->right to	zoom in, right->left to	zoom
     out, click	once to	restore	zoom to	100%) and mouse	button 3 opens the

     CTRL+Button 1 blurs or sharpens the image (drag left to blur, right to
     sharpen); CTRL+Button 2 rotates the image around the center point.

     A note about pan and zoom modes: In pan mode, if you reach	a window bor-
     der but haven't yet panned	to the end of the image, feh will warp your
     cursor to the opposite border so you can continue panning.

     When clicking the zoom button and immediately releasing it, the image
     will be back at 100% zoom.	 When clicking it and moving the mouse while
     holding the button	down, the zoom will be continued at the	previous zoom
     level.  The zoom will always happen so that the pixel on which you	en-
     tered the zoom mode remains stationary.  So, to enlarge a specific	part
     of	an image, click	the zoom button	on that	part.

     In	slideshow mode,	feh handles the	following signals:

	     Switch to next image

	     Switch to previous	image

     Here are some examples of useful option combinations. See also:

     feh /opt/images
	     Show all images in	/opt/images

     feh -r /opt/images
	     Recursively show all images found in /opt/images and subdirecto-

     feh -rSfilename /opt/images
	     Same as above, but	sort by	filename. By default, feh will show
	     files in the order	it finds them on the hard disk,	which is usu-
	     ally somewhat random.

     feh -t -Sfilename -E 128 -y 128 -W	1024 /opt/images
	     Show 128x128 pixel	thumbnails, limit window width to 1024 pixels.

     feh -t -Sfilename -E 128 -y 128 -W	1024 -P	-C
	     /usr/share/fonts/truetype/ttf-dejavu/ -e DejaVuSans/8 /opt/images
	     Same as above, but	enable thumbnail caching in ~/.thumbnails and
	     use a smaller font.

     feh -irFarial/14 -O index.jpg /opt/images
	     Make an index print of /opt/images	and all	directories below it,
	     using 14 point Arial to write the image info under	each thumb-
	     nail.  Save the image as index.jpg	and don't display it, just
	     exit.  Note that this even	works without a	running	X server

     feh --unloadable -r /opt/images
	     Print all unloadable images in /opt/images, recursively

     feh -f by_width -S	width --reverse	--list .
	     Write a list of all images	in the directory to by_width, sorted
	     by	width (widest images first)

     feh -w /opt/images/holidays
	     Open each image in	/opt/images/holidays in	its own	window

     feh -FD5 -Sname /opt/images/presentation
	     Show the images in	.../presentation, sorted by name, in
	     fullscreen, automatically change to the next image	after 5	sec-

     feh -rSwidth -A "mv %F ~/images/%N" /opt/images
	     View all images in	/opt/images and	below, sorted by width,	move
	     an	image to ~/image/image_name when enter is pressed

     feh --start-at ./foo.jpg .
	     View all images in	the current directory, starting	with foo.jpg.
	     All other images are still	in the slideshow and can be viewed

     feh --start-at foo.jpg *
	     Same as above

     feh --info	"exifgrep '(Model|DateTimeOriginal|FNumber|ISO|Flash)' %F |
	     cut -d . -f 4-" .
	     Show some EXIF information, extracted by exifprobe/exifgrep

     feh --action 'rm %F' -rl --max-dim	1000x800
	     Recursively remove	all images with	dimensions below or equal to
	     1000x800 pixels from the current directory.

     feh requires the jpegtran and jpegexiforient binaries (usually
     distributed in "libjpeg-progs" or similar)	for lossless rotation.

     To	view images from URLs such as http://, you need	feh compiled with
     libcurl support (enabled by default).  See	the VERSION section.

     On	systems	with Imlib2 >= 1.4.7 and giflib	>= 5.1.2, feh may be unable to
     load gif images. For affected mips, mipsel	and arm	devices, gif support
     is	completely broken, while on x86	/ x86_64 gifs can usually only be
     loaded if they are	the first image	in the filelist.  This appears to be
     an	Imlib2 and/or giflib bug introduced in giflib 5.1.2.  See
     <>	for details.
     Workaround: Use --magick-timeout 5	(or some other positive	value) to load
     gifs with imagemagick instead, or downgrade giflib	to 5.1.1.

     Thumbnail mode is somewhat	inefficient, and because of that not nearly as
     fast as it	could be.

     --scale-down does not take	window decorations into	account	and may	there-
     fore make the window slightly too large.

     If	you find a bug,	please report it to <> or via
     <>.  You are also	welcome	to direct any
     feh-related comments/questions/...	to #feh	on

     Please include the	feh version <the output	of "feh	--version">, steps to
     reproduce the bug and, if necessary, images to reproduce it.

     Plans for the following releases:
