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.

If you have a new feature suggestion or find a bug, please get in touch via http://commandlinefu.uservoice.com/

Get involved!

You can sign-in using OpenID credentials, or register a traditional username and password.

First-time OpenID users will be automatically assigned a username which can be changed after signing in.

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.

force change password for all user

Terminal - force change password for all user

User: romulusnr
Functions: cut getent passwd xargs
force change password for all user

Alternately for those without getent or only want to work on local users it's even easier:

cut -d: -f1 /etc/passwd|xargs -n1 passwd -e

Note that not all implementations of passwd support -e. On RH it would be passwd -x0 (?) and on Solaris it would be passwd -f.


There are 3 alternatives - vote for the best!

Terminal - Alternatives
while IFS=: read u x; do passwd -e "$u"; done < /etc/passwd

User: cfajohnson
Functions: passwd read

This assumes that te original's 'passwd -e' forces a user to change password; it doesn't in the versions I have.

for i in `cat /etc/passwd | awk -F : '{ print $1 }';`; do passwd -e $i; done

Know a better way?
