svc

SVC(1)							      General Commands Manual							    SVC(1)

NAME

       svc, ci, co, svclog - shell version control system

SYNOPSIS

       ci [-lu] file
       co [-l] [-r rev] file
       svclog file

OPTIONS

       -l     For ci, checkin, checkout again, and lock file

       -l     For co, checkout file and then lock the archive

       -u     After checking in, do not delete the file

       -r     Check out revision rev instead most recent revision

EXAMPLES

       ci -u file	   # Check in file

       co -l file	   # Check out file and lock archive

       co -r 2 file	   # Check out version 2

DESCRIPTION

       Svc  is the Shell Version Control system, patterned on RCS.  It maintains a sequence of versions in archive files, so that new versions can
       be checked in (added to the archive), and old versions can be checked out (made available).  To create an archive for  file,  check  it	in
       with  the  -u flag.  This action will prompt for a log message and then create an archive called file,S in the current directory, or in the
       subdirectory SVC if it exists.  The file will not be deleted, but will be made unwritable.

       To update the file, check it out with the -l flag.  Then modify it, and check it back in, giving a new message when prompted.   After  this
       process	has  been repeated many times, the archive will contain the entire history.  Any version can be checked out using the -r flag.	To
       get a printout of the history, use svclog.
