[SOLVED] /etc/passwd and /etc/passwd-

[curiousgirl]

I was looking around the files in /etc/ to see what they were and what they said, then I noticed there was two files called passwd, which confused me a lot for a second then I noticed one of them was actually passwd-.

I compared them and they only differed by one line:
< games:36:35:added by portage for gemrb:/usr/games:/bin/bash, which was in passwd but not passwd-.

Should these files both exist? If yes, why, what does having both do? If no, then its safe to say I can just delete passwd-?

Thanks muchly for your help.

Files whose names end in ~ are backups of old versions. Most Linux editors follow this convention. If there is a second edit, this backup file gets overwritten.

If you change a system configuration yourself, it's a good idea to save the original under a separate name so as to keep it permanently.

Ah, that's very useful.
