Opps one point I forgot if you are going to use it use the -q (quiet only outputs if a problem) and then copy these files (from a known good source) into a hidden directory. egrep, find, head, id, ls, netstat, ps, strings, sed, uname awk cut echo and ps and use the -p option to tell it to use only these files. That way it doesn't use ones that may be compromised already.
