Checking if the user exists in several systems

[johnson8582]

Hello,

In my network I have several (approximately 100) systems. I want to check if one user (for example johnson) exists in all the 100 systems. I cant login to each system and check it manually.

Is there any automated process which can simplify this task? Or is there any shell script I can run?

Please suggest me a solution for this.

Thanks,
~Johnson

could you modify johnson's login details so that, whenever johnson
logs in, an email is sent to you?

I can't login to each system and modify the profile. If I can login to each system and modify the profile, I wouldn't have raised my question here.

I want to simplify the task of manually logging into each system and checking for the existence of one user, by writing any shell script.

Hope, you understand the problem now.

Thanks,
