NAME
  install - Installs a command

SYNOPSIS

  install [-sS] [-c targetdir] [-g group] [-m mode] [-u owner] \
  file [searchdir ...]

  install [-osS] [-f targetdir] [-g group] [-m mode] [-u owner] \
  file [searchdir ...]

  install [-g group] [-iosS] [-m mode] [-n targetdir] [-u owner] \
  file [searchdir ...]

  install [-g group] [-MosS] [-m mode] [-u owner] file [searchdir ...]

  The install command installs file in a specific place within a file system.
  It is most often used in makefiles.

FLAGS

  -c targetdir
      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 flag can
      be used alone or with the -g, -m, -s, -S, or -u flags.

  -f targetdir
      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 flag can be used alone or with the
      -g, -m, -o, -s, -S, or -u flags.

  -g group
      Specifies a group other than bin for the destination file.

  -i  Ignores the default directory search list.  Searches for the file to be
      installed only in the directories specified on the command line (sear-
      chdir ...).  This flag cannot be used with the -c, -f, or -M flags.

  -M  Moves file to targetdir instead of copying it.  This flag cannot be
      used with the -c, -f, -i, or -n flags.

  -m mode
      Specifies a mode other than 755 for the destination file.

  -n targetdir
      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 flag cannot be used with the -c, -f, or -M flags.

  -o  Saves the old copy of file by renaming it OLDfile and leaving it in the
      directory where it was found.  This flag cannot be used with the -c
      flag.

  -u owner
      Specifies an owner other than bin for the destination file.

  -s  Suppresses the display of all but error messages.

  -S  Causes the binary to be stripped after installation; see strip(1).

DESCRIPTION

  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 indicat-
  ing 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.

EXAMPLES

   1.  To replace a command that already exists in one of the default direc-
       tories, 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.

   2.  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.

   3.  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.

   4.  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.

   5.  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.

   6.  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
       flag).  The messages that tell where the new command was installed are
       suppressed (a result of the -s flag).
