3.2. Committing your changes

When you have checked that the compiler is still compilable you decide to make a new version of backend.c.

$ cvs commit backend.c

cvs starts an editor, to allow you to enter a log message. You type in ``Added an optimization pass.'', save the temporary file, and exit the editor.

The environment variable $CVSEDITOR determines which editor is started. If $CVSEDITOR is not set, then if the environment variable $EDITOR is set, it will be used. If both $CVSEDITOR and $EDITOR are not set then the editor defaults to vi. If you want to avoid the overhead of starting an editor you can specify the log message on the command line using the `-m' flag instead, like this:

$ cvs commit -m "Added an optimization pass" backend.c
