[lithium@ph33r lithium]$ ls /etc/shadow*
[lithium@ph33r lithium]$ ls /etc/passwd*
/etc/passwd /etc/passwd- /etc/passwd.lock
what is the purpose of the shadow- and the passwd- and passwd.lock files? The data in them differs slightly from the shadow and passwd files (and passwd.lock is just a number). Can i delete these safely.
i've looked through google and read the shadow password howto.
