Mac OS X for Unix Geeks

Using CVS

When you register with Apple, you choose a username and password. You’ll need to use that username and password when you log into CVS. The first step is setting your CVSROOT environment variable. Under tcsh, issue this command:

setenv CVSROOT :pserver:[e-mail]:/cvs/Darwin

Under bash or zsh, use this command:

export CVSROOT=:pserver:[e-mail]:/cvs/Darwin

Replace username with your username. After you set this environment variable, you can log into CVS with cvs login:

                  % cvs login
(Logging in to [e-mail])
CVS password: ********

Checking out sources

To check out the source code for a module, use the checkout command:

                     cvs -z3 checkout [-r 
                     VERSION] modulename

The -z3 option tells CVS to use compression when transferring files.

Updating sources

To bring a module into sync with the latest changes to the repository, use the update command:

                     cvs -z3 update -P -d 
                     modulename

The -d option tells CVS to pick up any directories that were recently added, and -P tells CVS to prune any directories that were recently removed.

Tip

If you use modulename with the update command, you need to be in the same directory where you originally issued the checkout command. This will be the parent directory of the module’s top-level source directory. If you don’t specify a modulename, CVS will update only the files in and below your current working directory.
