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.

What others think

Not bad, but I can shorten it (by 24 characters). Replace the grep -v with sed 1d. Then combine that, the whitespace sed and the main sed into one BIG command:

ps -o etime `pidof firefox` | sed '1d;s/\s*//g;s/\(.*\)-\(.*\):\(.*\):\(.*\)/\1d \2h/;s/\(.*\):\(.*\):\(.*\)/\1h \2m/;s/\(.*\):\(.*\)/\1m \2s/'

with "=" ps rename header but if empty ps not show header line:

ps -o etime= `pidof firefox` | sed 's/\s*//g;s/\(.*\)-\(.*\):\(.*\):\(.*\)/\1d \2h/;s/\(.*\):\(.*\):\(.*\)/\1h \2m/;s/\(.*\):\(.*\)/\1m \2s/'
