What's the difference between the "group" and "group-" file?
I know what the /etc/group file is for, but I'm also seeing a /etc/group- file. What's the difference between the two?
The same group names and ids appear in both files. Only the last column (users) is different.
I'm running ubuntu 11.04
Though I cannot find any information in manual pages, I suppose it is a backup copy, as it is documented for /etc/shadow- in shadow manual page:
/etc/shadow-
Backup file for /etc/shadow.
