The install command installs file in a specific place
within a file system. It is most often used in makefiles.
Installs file in targetdir only if there is not already a
copy there. If there is a copy of file in targetdir, the
command issues a message to that effect and exits without
overwriting the file. This option can be used alone or
with the -g, -m, -s, -S, or -u options. Forces installation
of file in targetdir even if a copy already exists
there. If there is already a copy of file in targetdir,
the command sets the new copy's mode and owner to those of
the old copy. If there is not already a copy of file in
targetdir, the command sets the mode to 755 and the owner
to bin. This option can be used alone or with the -g, -m,
-o, -s, -S, or -u options. Specifies a group other than
bin for the destination file. Ignores the default directory
search list. Searches for the file to be installed
only in the directories specified on the command line
(searchdir ...). This option cannot be used with the -c,
-f, or -M options. Moves file to targetdir instead of
copying it. This option cannot be used with the -c, -f,
-i, or -n options. Specifies a mode other than 755 for
the destination file. Installs file in targetdir if there
is no copy in any of the searched directories (searchdir
...). Sets the mode of the file to 755 and the owner to
bin. This option cannot be used with the -c, -f, or -M
options. Saves the old copy of file by renaming it OLDfile
and leaving it in the directory where it was found.
This option cannot be used with the -c option. Specifies
an owner other than bin for the destination file. Suppresses
the display of all but error messages. Causes the
binary to be stripped after installation; see strip(1).
The install command copies (or moves) file into the appropriate
directory, retaining the owner and permissions of
the existing copy, if any. A newly created file has permission
code 755, owner bin, and group bin. The install
command writes a message telling you which files it is
replacing or creating and where they are going.
If you supply no options or search directories (searchdir
...), the install command searches the /bin, /usr/bin,
/etc, /lib, and /usr/lib directories in that order for a
file with the same name as file. The command overwrites
the first matching file with file and issues a message
indicating that it has done so. If no match is found, the
command tells you and exits without taking further action.
If any search directories (searchdir ...) are specified
on the command line, the install command searches them
before it searches the default directories.
To replace a command that already exists in one of the
default directories, enter: install fixit
This replaces the file fixit if it is found in the
/bin, /usr/bin, /etc, /lib, or /usr/lib directory.
Otherwise, the file fixit is not installed. For
example, if /usr/bin/fixit exists, then this file
is replaced by a copy of the file fixit in the current
directory. To replace a command that already
exists in a specified or default directory while
preserving the old version, enter: install -o
fixit /etc /usr/games
This replaces the file fixit if it is found in the
/etc or /usr/games directory, or in one of the
default directories. Otherwise, the file fixit is
not installed. If the file is replaced, the old
version is preserved by renaming it OLDfixit in the
directory in which it was found. To replace a command
that already exists in a specified directory,
enter: install -i fixit /u/judith/bin /u/bernice/bin
/usr/games
This replaces the file fixit if it is found in the
/u/judith/bin, /u/bernice/bin, or /usr/games directory.
Otherwise, the file is not installed. To
replace a command found in a default directory, or
install it in a specified directory if it is not
found, enter: install -n /usr/bin fixit
This replaces the file fixit if it is found in one
of the default directories. If the file is not
found, it is installed as /usr/bin/fixit. To
install a new command, enter: install -c /usr/bin
fixit
This creates a new command by installing a copy of
the fixit file as /usr/bin/fixit, but only if this
file does not already exist. To install a command
in a specified directory whether or not it already
exists, enter: install -f /usr/bin -o -s fixit
This forces the fixit file to be installed as
/usr/bin/fixit whether or not /usr/bin/fixit
already exists. The old version, if any, is preserved
by renaming it to /usr/bin/OLDfixit (a
result of the -o option). The messages that tell
where the new command was installed are suppressed
(a result of the -s option).
