Smile Legacy Account in /etc/passwd, /etc/shadow and/or /etc/group


Verify no legacy '+' entries exist in passwd, shadow, and group files Verify no legacy '+' entries exist in passwd, shadow, and group files

I have this command for this but it is not giving any kind of out put
grep ^+: /etc/passwd /etc/shadow /etc/group

i am runing "echo $?" then it is giving "1" it means their is not legacy account.
but i wan to see the out put for this i am sending you the script if legacy account is their so how can i delet it?

#!/bin/bash
#This script will give the information of legacy account.

LG=`grep '^+:' /etc/passwd /etc/shadow /etc/group`
val=$?

if [ $val -eq 0 ]
then

echo $LG

else

echo "Their is no Legacy Account"

fi

I believe the problem is that you won't (or shouldn't) have permission to read /etc/shadow, so grep will return 2, not 0. I think you're after something like:

Code:
LG=$(grep '^+:' /etc/passwd) #if they're in passwd, they're a user
if [$? -eq 0]; then 
    #We've found a user
    echo "We've found the user '+'!"
    sudo userdel '+'
    echo "Deleted."
else
    echo "Couldn't find the user '+'."
fi

I don't know - '+' isn't a valid name for a user, anyway.

The 'userdel' command in the code I posted already does this - it should remove them from /etc/{group,passwd,shadow}

If you consider the problem solved, please click 'SOLVED' at the top of the page
