I will enable it again when the project library will be shellchecked https://github.com/koalaman/shellcheck/wiki/SC1091 Refactor password policy check with one check by feature Previous file will now only look for bad passwords in /etc/shadow I added two checks that look for the compliant configuration lines in conf files /etc/logins.defs and /etc/pam.d/common-passwords FIX: merge chained sed and fix regex FIX: update regex to capture more output FIX: fix pattern to ignore commented lines, add apply Also add tests to ensure that commented lines are not detected as valid configuration CHORE: cleanup test situation with file and users removal IMP: add case insensitive option when looking for patterns in files CHORE: removed duplicated line in test file
