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 don't change the modification time of the tar-
	     get.  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 doesn't 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
	     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.

DIAGNOSTICS

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

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 conjuction with the -s option, temporary files named
	       INS@XXXX, where XXXX is decided by mkstemp(3), are created in
	       the target directory.

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.
