First I would leave off the last upslash in the search directory spec.
Second I would put the \ escape character in front of the * wildcard character.
Third, your time spec of -30 may be off by one. I believe that it will show the files modified in the last 29 days. Test it out and see. You may have to use -31 to get the files modified in the last 30 days. For example, my .bashrc was modified 11 days ago.
# ls -lah .bashrc
-rw-rw---- 1 root root 81 2009-05-04 17:15 .bashrc
# find -mtime -12 -name .bashrc
# find -mtime -11 -name .bashrc
Notice that .bashrc is not listed when I specified -11 as the time spec.
AND, I'm not using root to write this. I had a terminal window logged on as root so I used that to do my examples. I'm using a normal user account to do my regular work.
