easiest way to undo one file change in svn -

let's have following situation:

myrepo/   foo.txt   bar.txt   baz.txt   quux.txt   bingo.txt

in rev 419, changed foo.txt, bar.txt, , bingo.txt.

now discover error , keep foo.txt rev 418, leave changes in bar.txt , bingo.txt rev 419 intact, can commit rev 420 foo.txt same rev 418.

how can minimum of hassle?

this how, have rolled changes of previous commit.

the reverse merge : svn --revision (version revert):(version below it) <. or filename>

svn merge --revision 419:418 foo.txt svn commit -m "reverting commit ver:419 foo.txt"
