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/

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.

create and md5 sum of your password

create and md5 sum of your password without it showing up in your terminal or history.

Afterwards we overwrite the $p variable (thx to bazzargh)


There is 1 alternative - vote for the best!

Terminal - Alternatives

If you can do better, submit your command here.

What others think

Using a plain MD5 sum without salt to store passwords is not safe for any application which needs a password.

I used this after a user db has been attacked to check whether or not my password was among others in a dump of md5 sums.

While the password doesn't show up directly in your history, that command does, and p still holds your password. You should add ;p="" at the end of the command. If you wanted to hide the command from your history entirely, export HISTCONTROL=ignorespace and add a space to the start of the command

Comment by bazzargh 148 weeks and 5 days ago

alternatively one can substitute md5sum with opennssl

read -s p && echo -n $p |openssl md5;p=""
