Suppose while viewing the output of svn diff you determine that all the changes you made to a particular file are mistakes. Maybe you shouldn't have changed the file at all, or perhaps it would be easier to make different changes starting from scratch.
This is a perfect opportunity to use svn revert:
$ svn revert README Reverted 'README'
Subversion reverts the file to its pre-modified state by
overwriting it with the cached “pristine” copy
from the .svn area. But also note that
svn revert can undo
any scheduled operations—for
example, you might decide that you don't want to add a new
file after all:
$ svn status foo ? foo $ svn add foo A foo $ svn revert foo Reverted 'foo' $ svn status foo ? foo
svn revertITEM has exactly the same
effect as deleting ITEM from
your working copy and then running svn update -r
BASE ITEM. However,
if you're reverting a file, svn revert
has one very noticeable difference—it doesn't have
to communicate with the repository to restore your
file.
Or perhaps you mistakenly removed a file from version control:
$ svn status README
README
$ svn delete README
D README
$ svn revert README
Reverted 'README'
$ svn status README
README
