Yes, it should be -mtime
30 if you want exactly 30 days
+30 for 30 days and older
-30 for 30 days and younger

You can skip the single quotes. {} means substitute what the find
command found in earlier part, into the -exec section.

\; is the end of your -exec option. So, you could have another
option after that (ie: ... -exec rm -f {} \; -print)
However, this is a dangerous command. Run the following first to
see what it does. If you like the output, run it with 'rm -f'
instead of 'ls -l'
find /some/path -type f -mtime +30 -exec ls -l {} \;
