Reverting Changes in SVN

undo local changes in all files

$ svn revert -R .

undo local changes in a specific file

Useful, for example, if you want a clean, atomic commit but there's a file whose differences from last revision amount to an extra blank line (or something unimportant like that which isn't a real change and might mislead people who work with you).

$ svn revert your-file-name.txt

W.I.P.: This is an unfinished work in progress.
