Question

Actually very new user to bash.and I am logging into server using

ssh [e-mail]

and now I have to write script which will ensure that only ‘sam’ user can be logged in.

Can anybody help me out of this problem?

Answer 1

I’m not sure what exactly and where you’re trying to do, but maybe you’re talking about

[[ "$(id -un)" = "sam" ]] || { echo "Oh NO! You're a stranger!" ; exit 1; }

But generally, ssh has its own means of authentication.
