SCCS(1)			  BSD General Commands Manual		       SCCS(1)

NAME
     sccs — front end for the SCCS subsystem

SYNOPSIS
     sccs [-r] [-d path] [-p path] command [flags] [file ...]

DESCRIPTION
     Sccs is a front end to the SCCS programs that helps them mesh more
     cleanly with the rest of UNIX.  It also includes the capability to run
     “set user id” to another user to provide additional protection.

     Basically, sccs runs the command with the specified flags and args.  Each
     argument is normally modified to be prepended with “SCCS/s.”.

     Flags to be interpreted by the sccs program must be before the command
     argument.	Flags to be passed to the actual SCCS program must come after
     the command argument.  These flags are specific to the command and are
     discussed in the documentation for that command.

     Besides the usual SCCS commands, several “pseudo-commands” can be issued.
     These are:

     edit     Equivalent to “get -e”.

     delget   Perform a delta on the named files and then get new versions.
	      The new versions will have id keywords expanded, and will not be
	      editable.	 The -m, -p, -r, -s, and -y flags will be passed to
	      delta, and the -b, -c, -e, -i, -k, -l, -s, and -x flags will be
	      passed to get.

     deledit  Equivalent to delget except that the get phase includes the -e
	      flag.  This option is useful for making a checkpoint of your
	      current editing phase.  The same flags will be passed to delta
	      as described above, and all the flags listed for above except -e
	      and -k are passed to edit.

     create   Creates an SCCS file , taking the initial contents from the file
	      of the same name.	 Any flags to admin are accepted.  If the cre‐
	      ation is successful, the files are renamed with a comma on the
	      front.  These should be removed when you are convinced that the
	      SCCS files have been created successfully.

     fix      Must be followed by a -r flag.  This command essentially removes
	      the named delta, but leaves you with a copy of the delta with
	      the changes that were in it.  It is useful for fixing small com‐
	      piler bugs, etc.	Since it doesn't leave audit trails, it should
	      be used carefully.

     clean    This routine removes everything from the current directory that
	      can be recreated from SCCS files.	 It will not remove any files
	      being edited.  If the -b flag is given, branches are ignored in
	      the determination of whether they are being edited; this is dan‐
	      gerous if you are keeping the branches in the same directory.

     unedit   This is the opposite of an edit or a “get -e”.  It should be
	      used with extreme caution, since any changes you made since the
	      get will be irretrievably lost.

     info     Gives a listing of all files being edited.  If the -b flag is
	      given, branches (i.e., SID´s with two or fewer components) are
	      ignored.	If the -u flag is given (with an optional argument)
	      then only files being edited by you (or the named user) are
	      listed.

     check    Like info except that nothing is printed if nothing is being
	      edited, and a non-zero exit status is returned if anything is
	      being edited.  The intent is to have this included in an install
	      entry in a makefile to insure that everything is included into
	      the SCCS file before a version is installed.

     tell     Gives a newline-separated list of the files being edited on the
	      standard output.	Takes the -b and -u flags like info and check.

     diffs    Gives a diff listing between the current version of the pro‐
	      gram(s) you have out for editing and the versions in SCCS for‐
	      mat.  The -r, -c, -i, -x, and -t flags are passed to
	      get; the -l, -s, -e, -f, -h, and -b options are passed to
	      diff.  The -C flag is passed to diff as -c.

     print    This command prints out verbose information about the named
	      files.

     -r	      Runs sccs as the real user rather than as whatever effective
	      user sccs is “set user id” to.

     -d	      Specifies a root directory for the SCCS files.  The default is
	      the current directory.  If environment variable PROJECT is set,
	      it will be used to determine the -d flag.

     -p	      Defines the pathname of the directory in which the SCCS files
	      will be found; “SCCS” is the default.  The -p flag differs from
	      the -d flag in that the -d argument is prepended to the entire
	      pathname and the -p argument is inserted before the final compo‐
	      nent of the pathname.  For example, “sccs -d/x -py get a/b” will
	      convert to “get /x/a/y/s.b”.  The intent here is to create
	      aliases such as “alias syssccs sccs -d/usr/src” which will be
	      used as “syssccs get cmd/who.c”.

	      Certain commands (such as admin) cannot be run “set user id” by
	      all users, since this would allow anyone to change the autho‐
	      rizations.  These commands are always run as the real user.

EXAMPLES
     To get a file for editing, edit it, and produce a new delta:

	   sccs get -e file.c
	   ex file.c
	   sccs delta file.c

     To get a file from another directory:

	   sccs -p/usr/src/sccs/s. get cc.c

     or

	   sccs get /usr/src/sccs/s.cc.c

     To make a delta of a large number of files in the current directory:

	   sccs delta *.c

     To get a list of files being edited that are not on branches:

	   sccs info -b

     To delta everything being edited by you:

	   sccs delta `sccs tell -u`

     In a makefile, to get source files from an SCCS file if it does not
     already exist:

	   SRCS = <list of source files>
	   $(SRCS):
		sccs get $(REL) $@

ENVIRONMENT
     PROJECT	   The PROJECT environment variable is checked by the -d flag.
		   If it begins with a slash, it is taken directly; otherwise,
		   the home directory of a user of that name is examined for a
		   subdirectory “src” or “source”.  If such a directory is
		   found, it is used.

HISTORY
     The sccs command appeared in 4.3BSD.

BUGS
     It should be able to take directory arguments on pseudo-commands like the
     SCCS commands do.
