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.

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.

UpGuard checks and validates configurations for every major OS, network device, and cloud provider.

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.

This counts the number of httpd processes running.


There are 9 alternatives - vote for the best!

Know a better way?

If you can do better, submit your command here.

What others think

Actually, that line would count the number of httpd processes running... plus one.

To count foo processes reliably, try

pgrep foo | wc -l

FWIW, if you *need* to use grep, you can also avoid the spurious line using

ps aux | grep foo | grep -v grep | wc -l

'ps aux | grep [f]oo' is better and shorter than 'ps aux | grep foo | grep -v grep'
