1.3.4 Viewing differences

You do not remember modifying ‘driver.c’, so you want to see what has happened to that file.

 
$ cd tc
$ cvs diff driver.c

This command runs diff to compare the version of ‘driver.c’ that you checked out with your working copy. When you see the output you remember that you added a command line option that enabled the optimization pass. You check it in, and release the module.

 
$ cvs commit -m "Added an optimization pass" driver.c
Checking in driver.c;
/usr/local/cvsroot/tc/driver.c,v  <--  driver.c
new revision: 1.2; previous revision: 1.1
done
$ cd ..
$ cvs release -d tc
? tc
