What's this?

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.

Universal configuration monitoring and system of record for IT.

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.

Shows users and 'virtual users' on your a unix-type system


There are 4 alternatives - vote for the best!

Terminal - Alternatives
ps -eo user | sort -u

User: dfaulkner
Functions: ps sort

Shows a list of users that currently running processes are executing as.

YMMV regarding ps and it's many variants. For example, you might need:

ps -axgu | cut -f1 -d' ' | sort -u
ps -axgu | cut -f1 -d' ' | sort -u
sudo lsof|sed 's/ */ /g'|cut -f3 -d' '|sort -u

User: binaryten
Functions: cut sed sort sudo

Most systems (at least my macbook) have system users defined, such as _www and using "users" for example will not list them. This command allows you to see who the 'virtual' users are on your system.

Know a better way?

If you can do better, submit your command here.

What others think

This is typical case of "awk abuse" ... It's rather a job for cut(1):

cut -d: -f1 /etc/passwd | sort
