INSTALL(1)                  General Commands Manual                 INSTALL(1)


NAME

     install - install binaries


SYNOPSIS

     install [-bCcDdFpSs] [-B suffix] [-f flags] [-g group] [-m mode]
             [-o owner] source ... target ...


DESCRIPTION

     The source file(s) are copied to the target file or directory.  If the
     target file already exists, it is either renamed to file.old if the -b
     option is given or overwritten if permissions allow.  An alternate backup
     suffix may be specified via the -B option's argument.  If the -d option
     is given, target directories are created, and no files are copied.

     The options are as follows:

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

     -b         Backup any existing files before overwriting them by renaming
                them to file.old.  See -B for specifying a different backup
                suffix.

     -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 target.

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

     -D         Create all leading components of the target before installing
                into it.

     -d         Create directories.  Missing parent directories are created as
                required.  This option cannot be used with the -B, -b, -C, -c,
                -f, -p, -S, or -s options.

     -F         Flush the file's contents to disk.  When copying a file, use
                the fsync(2) function to synchronize the installed file's
                contents with the on-disk version.

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

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

     -m mode    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 owner   Specify an owner.  A numeric UID is allowed.

     -p         Preserve the modification time.  Copy the file, as if the -C
                (compare and copy) option is specified, except if the target
                file doesn't already exist or is different, then preserve the
                modification time of the 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 /usr/bin/strip to strip binaries so
                that install can be portable over a large number of systems
                and binary types.  If the environment variable STRIP is set,
                it is used instead.

     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

     STRIP  For an alternate strip(1) program to run.  Default is
            /usr/bin/strip.


FILES

     INS@XXXXXXXXXX  If either -S option is specified, or the -C or -p option
                     is used in conjunction with the -s option, temporary
                     files named INS@XXXXXXXXXX, where XXXXXXXXXX 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.


SEE ALSO

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


HISTORY

     The install utility appeared in 4.2BSD.


CAVEATS

     The -C, -D, -F, -p, and -S flags are non-standard and should not be
     relied upon for portability.

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