In regular expressions the asterisk is not a wildcard in the same way as in
DOS/Windows.  Instead, it is read as "zero or more of the previous
character or symbol."  So what you probably want is ".*".  The dot "." is a
one-character-width wildcard, which is why it needs to be escaped if you
want to match a literal dot.  So ".*" means zero or more of any character.

Also, a regular expression match is applied only when the match string
STARTS with a percent.

Here, you are asking to match zero or more slash characters before a ".sql".

Doesn't start with percent.

Again, ".*" rather than "*".

Try this:


FILE %/Volumes/MySQL_Backups/mysql_backup_.*\.sql red mtime<86400

This should go red if the matching file is older than 1 day.
