A.16.2 rdiff examples

Suppose you receive mail from foo@example.net asking for an update from release 1.2 to 1.4 of the tc compiler. You have no such patches on hand, but with CVS that can easily be fixed with a command such as this:

$ cvs rdiff -c -r FOO1_2 -r FOO1_4 tc | \
> Mail -s 'The patches you asked for' foo@example.net

Suppose you have made release 1.3, and forked a branch called ‘R_1_3fix’ for bug fixes. ‘R_1_3_1’ corresponds to release 1.3.1, which was made some time ago. Now, you want to see how much development has been done on the branch. This command can be used:

$ cvs patch -s -r R_1_3_1 -r R_1_3fix module-name
cvs rdiff: Diffing module-name
