install copies files while setting their permission modes and, if
possible, their owner and group.
In the first of these invocation forms, the source file is copied to the
dest target file. In the second, each of the source files are
copied to the destination directory. In the last, each directory
(and any missing parent directories) is created.
install is similar to cp, but allows you to control the attributes
of destination files. It is typically used in Makefiles to copy programs into
their destination directories. It refuses to copy files onto themselves.
Ignored; for compatibility with old Unix versions of
Create each given directory and any missing parent
directories, setting the owner, group and mode as given on the command
line or to the defaults. It also gives any parent directories it creates
those attributes. (This is different from the SunOS 4.x install,
which gives directories that it creates the default attributes.)
Create all leading components of the dest except the
last, then copy source to dest. This option is useful in the
first format in the synopsis, above. (New in fileutils-4.0.)
-g group, --group=group
Set the group ownership of installed files or directories
to group. The default is the process's current group. group
may be either a group name or a numeric group id.
-m mode, --mode=mode
Set the permissions for the installed file or directory to
mode, which can be either an octal number, or a symbolic mode as in
chmod, with 0 as the point of departure. The default mode is 0755 -
read, write, and execute for the owner, and read and execute for group and
-o owner, --owner=owner
If install has appropriate privileges (is run as
root), set the ownership of installed files or directories to
owner. The default is `root'. owner may be either a user
name or a numeric user ID.
Strip the symbol tables from installed binary
The GNU versions of programs like cp, mv, ln,
install and patch will make a backup of files about to be
overwritten, changed or destroyed if that is desired. That backup files are
desired is indicated by the -b option. How they should be named is specified
by the -V option. In case the name of the backup file is given by the name of
the file extended by a suffix, this suffix is specified by the -S option.
Make backups of files that are about to be overwritten or
-S SUFFIX, --suffix=SUFFIX
Append SUFFIX to each backup file made. If this
option is not specified, the value of the SIMPLE_BACKUP_SUFFIX
environment variable is used. And if SIMPLE_BACKUP_SUFFIX is not
set, the default is `~'.
Specify how backup files are named. The
METHOD argument can be `numbered' (or `t'), `existing' (or `nil'), or
`never' (or `simple'). If this option is not specified, the value of the
VERSION_CONTROL environment variable is used. And if
VERSION_CONTROL is not set, the default backup type is `existing'.
This option corresponds to the Emacs variable `version-control'. The valid
METHODs are (unique abbreviations are accepted):
Always make numbered backups.
Make numbered backups of files that already have them,
simple backups of the others.
