DRG CVS HOWTO: One Page Reference

• To checkout a fresh local copy of the DRG source tree:
  cvs -d /projects/drg/CVSROOT checkout drg

  The source tree will be in drg/ off of the current directory.

• To update your local copy from the lastest changes in the repository:
  cd ~/drg; cvs update -Pd

  You will see a list of all the modified files with code letters indicating their status:
  U,P - updated R - locally removed M - locally modified A - locally added C - conflict ? - not in CVS

• To commit your changes to the repository:
  cd ~/drg; cvs commit

  It will pull up an emacs buffer for you to type up a log entry. If you made some changes that you don't like, rm the file, then update into the directory to replace with a repository copy. You should commit only working versions and do so every time you have made useful changes.

• To add a file to the repository:
  cvs add filename

  The file won't actually be added until you commit your changes as above. Do not add object files (only source files).

• To remove a file from the repository:
  rm filename
cvs remove filename

  The file won't actually be removed until you commit your changes as above. The file must be deleted first, or cvs remove won't work. Do this with care. Make sure the file is not needed anymore. It is possible to undo this through CVS, but it is a pain in the ass.

• To get the status of a local file:
  cvs status -v filename

  This will print out the current status of the file, including whether it's been locally modified. You can do this for whole directories too.

• To remove a local copy of the source tree:
  One generally keeps a checked out directory around and simply runs CVS update to retrieve new changes. If you don't need it anymore, just rm -r the directory. Make sure you have committed any changes you want to keep, and don't have any other useful files there!
