INSTALL(1)                   BSD Reference 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

     -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. Failure to change ownership or
                modes does not make the operation unsuccessful.

     -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 execs 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.

     Upon successful completion a value of 0 is returned. Otherwise, a value
     >0 is returned.


     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.


     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 ab-
