2.1 Telling CVS where your repository is

There are several ways to tell CVS where to find the repository. You can name the repository on the command line explicitly, with the -d (for "directory") option:

cvs -d /usr/local/cvsroot checkout yoyodyne/tc

Or you can set the $CVSROOT environment variable to an absolute path to the root of the repository, /usr/local/cvsroot in this example. To set $CVSROOT, csh and tcsh users should have this line in their .cshrc or .tcshrc files:

setenv CVSROOT /usr/local/cvsroot

sh and bash users should instead have these lines in their .profile or .bashrc:

export CVSROOT

A repository specified with -d will override the $CVSROOT environment variable. Once you’ve checked a working copy out from the repository, it will remember where its repository is (the information is recorded in the CVS/Root file in the working copy).

The -d option and the CVS/Root file both override the $CVSROOT environment variable. If -d option differs from CVS/Root, the former is used. Of course, for proper operation they should be two ways of referring to the same repository.
