INSTALL(1)		FreeBSD	General	Commands Manual		    INSTALL(1)

NAME
     install --	install	binaries

SYNOPSIS
     install [-bCcMpSsv] [-B suffix] [-f flags]	[-g group] [-m mode]
	     [-o owner]	file1 file2
     install [-bCcMpSsv] [-B suffix] [-f flags]	[-g group] [-m mode]
	     [-o owner]	file1 ... fileN	directory
     install -d	[-v] [-g group]	[-m mode] [-o owner] directory ...

DESCRIPTION
     The file(s) are copied to the target file or directory.  If the destina-
     tion is a directory, then the file	is copied into directory with its
     original filename.	 If the	target file already exists, it is either
     renamed to	file.old if the	-b option is given or overwritten if permis-
     sions allow.  An alternate	backup suffix may be specified via the -B
     option's argument.

     The options are as	follows:

     -b	     Back up any existing files	before overwriting them	by renaming
	     them to file.old.	See -B for specifying a	different backup suf-
	     fix.

     -B	suffix
	     Use suffix	as the backup suffix if	-b is given.

     -C	     Copy the file.  If	the target file	already	exists and the files
	     are the same, then	do not change the modification time of the
	     target.  If the target's file flags and mode need not to be
	     changed, the target's inode change	time is	also unchanged.

     -c	     Copy the file.  This is actually the default.  The	-c option is
	     only included for backwards compatibility.

     -d	     Create directories.  Missing parent directories are created as
	     required.

     -f	     Specify the target's file flags; see chflags(1) for a list	of
	     possible flags and	their meanings.

     -g	     Specify a group.  A numeric GID is	allowed.

     -M	     Disable all use of	mmap(2).

     -m	     Specify an	alternate mode.	 The default mode is set to rwxr-xr-x
	     (0755).  The specified mode may be	either an octal	or symbolic
	     value; see	chmod(1) for a description of possible mode values.

     -o	     Specify an	owner.	A numeric UID is allowed.

     -p	     Preserve the access and modification times.  Copy the file, as if
	     the -C (compare and copy) option is specified, except if the tar-
	     get file does not already exist or	is different, then preserve
	     the access	and modification times of the source file.

     -S	     Safe copy.	 Normally, install unlinks an existing target before
	     installing	the new	file.  With the	-S flag	a temporary file is
	     used and then renamed to be the target.  The reason this is safer
	     is	that if	the copy or rename fails, the existing target is left
	     untouched.

     -s	     install exec's the	command	strip(1) to strip binaries so that
	     install can be portable over a large number of systems and	binary
	     types.  See below for how install can be instructed to use
	     another program to	strip binaries.

     -v	     Cause install to be verbose, showing files	as they	are installed
	     or	backed up.

     By	default, install preserves all file flags, with	the exception of the
     ``nodump''	flag.

     The install utility attempts to prevent moving a file onto	itself.

     Installing	/dev/null creates an empty file.

ENVIRONMENT
     The install utility checks	for the	presence of the	STRIPBIN environment
     variable and if present, uses the assigned	value as the program to	run if
     and when the -s option has	been specified.

FILES
     INS@XXXX  If either -S option is specified, or the	-C or -p option	is
	       used in conjunction with	the -s option, temporary files named
	       INS@XXXX, where XXXX is decided by mkstemp(3), are created in
	       the target directory.

EXIT STATUS
     The install utility exits 0 on success, and >0 if an error	occurs.

COMPATIBILITY
     Historically install moved	files by default.  The default was changed to
     copy in FreeBSD 4.4.

SEE ALSO
     chflags(1), chgrp(1), chmod(1), cp(1), mv(1), strip(1), mmap(2), chown(8)

HISTORY
     The install utility appeared in 4.2BSD.

BUGS
     Temporary files may be left in the	target directory if install exits
     abnormally.

     File flags	cannot be set by fchflags(2) over a NFS	file system.  Other
     file systems do not have a	concept	of flags.  The install utility will
     only warn when flags could	not be set on a	file system that does not sup-
     port them.

     The install utility with -v falsely says a	file is	copied when -C snaps
     hard links.
