* only show syntax errors

* Add support for ss

Added runtime fallback to ss when netstat is unavailable, with a clear failure when neither exists.

* Fix shell injection risk

apply fixes (safe open, strict/warnings, key whitelist, error handling).

* Update query_unix_partitions.pl

* Update unix_users.pl

add use strict/warnings  to flag issues
add better error handling
