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.

There's a little difference between these 2:

# cat /etc/*issue

Welcome to SUSE Linux Enterprise Server 10 SP2 (x86_64) - Kernel \r (\l).

# uname -a

Linux ticket #1 SMP Fri Jan 16 14:59:01 UTC 2009 x86_64 x86_64 x86_64 GNU/Linux

lsb_release -d

That only works if you have LSB installed. My distro didn't install it, I had to add it later.

I only get this:

cat /etc/*issue

Debian GNU/Linux 5.0 \n \l

That's what you are supposed to get. I work for a hosting company and do lots of VPS support.

cat /etc/issue

makes quick work of trying to figure out what type of guest image you are dropping into.
