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

     install -- install binaries

     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 ...

     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-

     -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

     -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

     -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.

     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.

     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.

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

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

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

     The install utility appeared in 4.2BSD.

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

     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.
