Shadow file help
As a part of linux hardening

In shadow file all Application accounts which are not locked must contain only an asterisk “*” in the Passwd field.

But how would i do it by using command?

Is there any way other than modifying shadow file to accomplish this task?

This statement is ambiguous and makes no sense. When there is a password in the Shadow File the password field in the Password File is an asterisk.

Normally it is achieved by:

passwd -l username

And in this forum, I found a script to automate:
