Hyphen is missing in formation of CMD in mmin parameter

In formation of command a hyphen is missing ; that causes the cmd to always return zero . in mmin we need to provide (-) to ruun the command properly.

Expected :$CMD = “/bin/find ” . $pattern . ” -type f -mmin ” . -$mmin . ” 2>/dev/null| /usr/bin/wc -l”;

Otherwise the plugin is excellent and runs great.
