INSTALL(1) General Commands Manual INSTALL(1)
install - install binaries
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:
-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
-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
-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
-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
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, -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
