Users who have never changed their password from /etc/shadow.
Hello,

I have to do a script which returns users who have never changed their password from /etc/shadow.
Here is what have I done and I'm not sure if it's ok.
I tried to return just users who doesn;t have password set or are locked.
Can be there other kind of user who never changed the password?

Code:
#!/bin/sh -x
USRFILE="/etc/shadow"

for i in `grep -v '^+' $USRFILE | cut -d: -f1,2`
do
  userpname=`echo $i|cut -d: -f1`
  password=`echo $i|cut -d: -f2`
  if [ "x$password" -eq "x*LK*" ] || [ "x$passwd" -eq "xNP" ]
  then
    if [ "$RESULT" = "PASS" ]
      then
        RESULT="FAIL"
        REASON="Users who have changed their password were found"
      fi
      echo "$userpname user in “/etc/shadow” without changed password." 
  fi
done


thanks and regards,
catalint

See the "logins" command (specifically -xto options). All the information is there (albeit with American dates).

By the way. NP means "no password" which is a security risk. This is different from having a last changed date of "000000".
