install [-bCcDdFpSs] [-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:

suffix
Use suffix as the backup suffix if -b is given.
Backup any existing files before overwriting them by renaming them to file.old. See -B for specifying a different backup suffix.
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.
Copy the file. This is actually the default. The -c option is only included for backwards compatibility.
Create all leading components of the target before installing into it.
Create directories. Missing parent directories are created as required. This option cannot be used with the -B, -b, -C, -c, -f, -p, or -s options.
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.
flags
Specify the target's file flags. (See chflags(1) for a list of possible flags and their meanings.)
group
Specify a group. A numeric GID is allowed.
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.
owner
Specify an owner. A numeric UID is allowed.
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.
Safe copy. This option has no effect and is supported only for compatibility. When installing a file, a temporary file is created and written first in the destination directory, then atomically renamed. This avoids both race conditions and the destruction of existing files in case of write failures.
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.

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

INS@XXXXXXXXXX
Temporary files created in the target directory by mkstemp(3).

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, -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.
