svn revert — Undo all local edits.
Reverts any local changes to a file or directory and resolves any conflicted states. svn revert will revert not only the contents of an item in your working copy, but also any property changes. Finally, you can use it to undo any scheduling operations that you may have performed (e.g., files scheduled for addition or deletion can be “unscheduled”).
Discard changes to a file:
$ svn revert foo.c Reverted foo.c
If you want to revert a whole directory of files,
$ svn revert --depth=infinity . Reverted newdir/afile Reverted foo.c Reverted bar.txt
Lastly, you can undo any scheduling operations:
$ svn add mistake.txt whoops A mistake.txt A whoops A whoops/oopsie.c $ svn revert mistake.txt whoops Reverted mistake.txt Reverted whoops $ svn status ? mistake.txt ? whoops
svn revert is inherently dangerous, since its entire purpose is to throw away data—namely, your uncommitted changes. Once you've reverted, Subversion provides no way to get back those uncommitted changes.
If you provide no targets to svn revert, it will do nothing. To protect you from accidentally losing changes in your working copy, svn revert requires you to explicitly provide at least one target.
