Subversion Commit Fails – directory is already locked

I issued the subversion command-line command from windows dos prompt:

svn commit {path} -m ‘automated server backup’

to which subversion responsed:

Commit Failed
Working copy {path} locked
{Path} is already locked
run ‘svn cleanup’ to rmove locks

I tried svn cleanup and it didn’t help.  After a lot of trial and error, I changed the single quotes to double quotes in the -m paramaters.  Voila.  Subversion was ready to do my bidding.

svn commit {path} -m “automated server backup”
