commandlinefu.com is the place to record those command-line gems that you return to again and again.

Delete that bloated snippets file you've been using and share your personal repository with the world. That way others can gain from your CLI wisdom and you from theirs too. All commands can be commented on, discussed and voted up or down.

Stay in the loop…

Follow the Tweets.

Every new command is wrapped in a tweet and posted to Twitter. Following the stream is a great way of staying abreast of the latest commands. For the more discerning, there are Twitter accounts for commands that get a minimum of 3 and 10 votes - that way only the great commands get tweeted.

Psst. Open beta.

Wow, didn't really expect you to read this far down. The latest iteration of the site is in open beta. It's a gentle open beta-- not in prime-time just yet. It's being hosted over at UpGuard (link) and you are more than welcome to give it a shot. Couple things:

  • » The open beta is running a copy of the database that will not carry over to the final version. Don't post anything you don't mind losing.
  • » If you wish to use your user account, you will probably need to reset your password.
Your feedback is appreciated via the form on the beta page. Thanks! -Jon & CLFU Team

List all groups and the user names that were in each group

Terminal - List all groups and the user names that were in each group
for u in `cut -f1 -d: /etc/passwd`; do echo -n $u:; groups $u; done | sort

User: hemanth
Functions: echo groups
List all groups and the user names that were in each group

"cut" the user names from /etc/passwd and then running a loop over them.


There is 1 alternative - vote for the best!

Terminal - Alternatives
groups $(cut -f1 -d":" /etc/passwd) | sort

What others think

Glad you're enjoying our blog. In future, however, it would be nice if you gave some attribution when you're posting our content here on commandlinefu. This one is from http://blog.commandlinekungfu.com/2009/06/episode-44-users-groups-part-ii.html

By the way, this command lists all groups that each user is a member of, not the users in each group. For the latter answer, see http://blog.commandlinekungfu.com/2009/06/episode-43-users-groups.html

it's shorter in my fedora:

for u in `cut -f1 -d: /etc/passwd`; do groups $u; done | sort
