       shed (Simple Hex	EDitor)

       shed [OPTIONS] [FILE]

       A simple	hex editor with	a pico-style interface.

       Each  line  of  the  shed display represents one	byte of	the file. Each
       lines consists of the offset of that byte from the start	of  the	 file,
       the  ascii  value  of  the  byte,  and then the byte's value in various
       bases. All values are unsigned.

       When a command asks you for input, entering  a  zero-length  string  or
       pressing	 ^C will cancel	the command.  When searching, entering a zero-
       length string will use the previous search word,	if one exists.

       Note that there is no save key. This is because the file	is not	loaded
       into memory, so when you	edit it	the change is made directly to disk.

       -r / --readonly
	      open FILE	read only

       -s / --start=OFFSET
	      position cursor to offset

       -H / --hex
	      start in hex mode	(hex offsets etc.)

       -L / --length=LENGTH
	      set  length  of  file  to	LENGTH.	Useful for special files where
	      shed cannot obtain the length with stat.

       -h / --help
	      show help	and exit

       -v / --version
	      show version and exit

       arrow keys
	      move cursor around

       pgup / ^Y
	      cursor up	16 pgdown / ^V cursor down 16

       home / ^A
	      start of line (ascii column)

       end / ^E
	      end of line (binary column)

       space / e
	      edit value at cursor. You	are asked to enter the	new  value  in
	      the  format  of the current column the cursor is in - eg.	if you
	      are in the hex column, it	will ask for the new value in hex.

       1 / 2 / 4
	      set size of cursor in bytes, in the hex/dec/oct columns (and bi-
	      nary if in traditional mode).

       ` (backtick)
	      toggle  the endianness of	multi-byte values (when	cursor size is
	      2	or 4)

       s / w / ^w / f /	F3
	      search. Search string is asked for in the	format of the  current
	      cursor column.  In ascii,	just enter the string in ascii.	In the
	      others, enter the	values	seperated by spaces.  eg to search for
	      ABC  from	the decimal column you would enter "65 66 67" (without
	      the quotes).

       ^f / ^b
	      search shortcut for forwards/backwards respectivly.

       r / n / F3
	      repeat previous search

       t      toggle whether offset numbers and	cursor position	etc are	in dec
	      or hex.

       b      toggle  binary  mode  column  behaviour (bit edit	mode vs	tradi-

       d      dump to file.

       j      jump to byte. enter a byte number, or 'top'  or  'end'.  Can  be
	      suffixed with K, M or G.

       a      change  the mode of the ascii column (printable only/c-style ex-
	      tended chars/'man	ascii' descriptions)

       p      toggle 'preview' mode.

       x / ^x exit
