Subversion. It’s not Git. And now you need to use it and you accidentally added something you didnt mean to but you caught yourself before commit, right? Right? There’s a fix for that. Here is a tasty bit of BASH from Krishnan Cheanni. Read more at his blog: here.
If you do not want to add a certain file to your subversion repository, but it is already marked to be committed (by an already issued svn add command) you can just type:
svn revert file.ext
to undo the add command.
If you remember to do it before the corresponding svn commit, doing this helps keeping the repository to a decent size. If you already commited the changes, you can remove it using svn delete (and an extra –force argument, if needed), but the space is wasted.
