Linux users rely on community support. Often asked to post some command line returns they copy-paste the returns without question. I do the same. The Fedora ABRT tool got me thinking (it warns about debug logs containing sensitive security or privacy information) - are there certain bits of information people should delete when posting terminal returns online?

What comes to my mind:
user names
MAC address
partition identification numbers - GUUID (if GPT is used)
partition labels

Public IP address / IP address, Hostname, SSH key, Passwords ...

Other private / sensitive info that could be visible as a result of some command output (web browser history, identity card number, bank account number ....)

In general, sensitive can be everything that contains your own specific data / information (e.g. what is specific just for you). Information common to all of us (e.g. we all have the same on our systems) are probably not so dangerous but it all depends on the level of actual security paranoia :-)
