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/
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.
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.
Use your favourite RSS aggregator to stay in touch with the latest commands. There are feeds mirroring the 3 Twitter streams as well as for virtually every other subset (users, tags, functions,…):

This is useful to set the DOIT_SERVER for the doit remote execution agent ( http://www.chiark.greenend.org.uk/~sgtatham/doit/ )
export DOIT_HOST=$(who -m | sed 's/.*(\(.*\)).*/\1/')
Note that SSH_CLIENT variable can be lost if you use su or sudo (if set to reset vars)
Telnet will make a tcp connection to a remote ip/port to test connectivity. If it times out, it's not reaching the host (maybe the firewall is blocking it). If connection is refused, it's reaching the host, but either the service is not listening on that port, or it's locked.
If you need to create a profile and are already running Firefox, you don't need to close it to do it. Also, if you don't know the exact name of the profile, this would allow you to pick from a list.
Use this command to see logs update in real time
I think this is the cleanest way of getting the current working directory of a script. It also works on osx, Linux, and probably bsd as well..
