INSTALL(1)                  General Commands Manual                 INSTALL(1)


     install - install binaries


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


     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

     -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 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 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.


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


     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.


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


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


     The install utility appeared in 4.2BSD.


     The -C, -p, and -S flags are non-standard and should not relied upon for

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