SVN: How to ignore a modified file on commit? [duplicate]

Question

I edited some files in svn, like this:

$svn st
M  a
M  b
...

Now, I want to commit my changes to svn, for some reason, I don't want to commit file b, is there any quick way or command to ignore the modified file b?

Finally, I use @yzucker Solution 1, cp, revert and commit. Changelists is too heavy, thank you all.

Answer 1

You can use the Changelist Feature of newer Subverion clients as shown in this short example session:

$ svn st
M       a
M       b

$ svn cl task1 a
$ svn cl task2 b

$ svn st
--- Changelist 'task1':
M       a
--- Changelist 'task2':
M       b

$ svn ci --cl task1 -m "checking in only task 1 stuff"
Sending        a
Committed revision 11.

Answer 2

Alas, the commit many files with some annoying changes ignored problem.

Solution 1: copy, revert and commit

$cp b /tmp/
$svn revert b
$svn commit -m 'commit message'
$mv /tmp/b ./

Solution 2: copy, commit, reverse the effect of b, recommit b

$cp b /tmp/
$svn commit -m 'commit message'
$svn merge -c -{new revision} b
$svn commit b -m 'revert message for b'
$cp /tmp/b ./b

The second approach is less preferable since you introduce broken code in svn.
