Script to retrieve users from couple linux virtual machines

amdjml · 03-07-2014, 11:39 AM

Hi there linux community,

At home, I have setup a esxi server on an old desktop of mine. I have then installed about 5 virtual machines, which is a combination of debian and ubuntu and each box has about 3-7 users.

My question is, how can I write a script/a command that will go through my network, find these linux servers and extract the usernames from each and report it back to me?

Is this something can be easily achieved or do I need to know scripting in details?

Any help is much appreciated.

Your question seems to answer itself. If you want to write a script, you would very obviously need to know HOW to write scripts. You would need to ssh to each system, and probably use cat to look at the /etc/passwd file.

There are MANY easily-found scripting tutorials, and scripts already exist to list users...a Google search can turn up lots. Come back and post what you've written/tried, and where you're stuck. But this isn't the place to come and have people write scripts for you.

Thank you for your comment. Perhaps my comment was a bit vague, I was not expecting anyone to write the script for me, but rather point me to a direction and the logic behind doing something like that. I will look into your suggestion.
