Synopsis

                  ci [options] files
               

Check in revisions. ci stores the contents of the specified working files into their corresponding RCS files. Normally, ci deletes the working file after storing it. If no RCS file exists, then the working file is an initial revision. In this case, the RCS file is created and you are prompted to enter a description of the file. If the RCS file exists, ci increments the revision number and prompts you to enter a message that logs the changes made. If a working file is checked in without changes, the file reverts to the previous revision.

The mutually exclusive options -u, -l, and -r are the most common. Use -u to keep a read-only copy of the working file (for example, so that the file can be compiled or searched). Use -l to update a revision and then immediately check it out again with a lock. This allows you to save intermediate changes but continue editing (for example, during a long editing session). Use -r to check in a file with a different release number. ci accepts the standard options -q, -V, -x, and -z.
