SVN commands

Check out the file
svn co https://victorio.uit.no/langtech/trunk main --username
... where you have replaced with the username you have aquired from the admin. This will enable you to check in your work. If you don't have a user name or just want to browse our code, just skip the username.
Update your working copy
svn up
Scedule a file for addition
svn add filename
Scedule a file for deletion
svn delete filename
You may also copy and move files and directories with these two commands, but read about them in the svn book first:
svn copy filename
svn move filename
Examine your changes
svn status
Examine the file history
svn log FILE
Change the commit message for a specific revision
svn propedit svn:log --revprop -r REV FILE
This will bring up the existing log text for the specified revision in your default editor (typically Emacs), where you can edit and change it as you want. This is useful if you accidentally committed some changes with an empty or uninformative log message.
Compare your modified file to the version in the repository
svn diff FILE
Compare some earlier versions, say here versions 123 and 120
svn diff -r 123:120 FILE
Undo your local changes (ie revert to the repository status)
svn revert FILE
Resolve Conflicts (Merge Others' Changes)
svn update
svn resolved
Commit your changes
svn ci -m "Your description of the changes here." FILE
(Note that the above changes, add, delete, copy, move, must all be committed by ci in order to take effect)
