Terminal command not showing output, but it did previously

Symptoms

You are executing a command in Terminal that is not showing any output such as:

[09:32:52 root@myserver ~]cPs# /scripts/check_cpanel_rpms 

[09:51:23 root@myserver ~]cPs# 

Description 

This is expected behaviour The check_cpanel_rpms script is written in such a way that it shows output only if there is an error, otherwise it just exits without printing any output.

Workaround

If a command gives a different or no output then something changed, in the above example the check_cpanel_rpms script does not give any output because all cPanel packages are correctly installed right now.
