Hi

copy the box1 /etc/passwd file to /etc/passwd_box1.And then ftp that file to box 2 and then use diff command

diff /etc/passwd /etc/passwd_box1

Hi

If you did that then you got the difference between these files and the users.

Hi Fizan,

If you want to compare the password file try this. First take the login names from server1 using this command.

#cat /etc/passwd |cut -d: -f1 > /tmp/logins

Copy the /tmp/logins file to server2 then run these commands.

# for i in `cat /tmp/logins`
> do
> grep $i /etc/passwd > /dev/null
> if [ $? -eq 0 ]
> then
> echo "$i account is exist on the server2"
> else
> echo "$i account does not exist on the server2"
> fi
> done

It will give you the output like which account exist on the server2 and which account does not exist.

Hope it helps you

You can get the two files and sort them. Then use comm(1) to select which:
comm -23 pwd.1 pwd.2 # users on 1 and not 2
comm -13 pwd.1 pwd.2 # users on 2 and not 3
