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,…):

Log scaled histogram so that you can see large files even if there is a single HUGE file in the directory. Also makes sure the histogram is fullscreen for best chance of readable file names.
Will track your mouse and save it to a file.
You can use gnuplot to graph it:
gnuplot -persist <(echo "unset key;unset border;unset yzeroaxis;unset xtics;unset ytics;unset ztics;plot './mouse-tracking' with points lt 1 pt 6 ps variable")
draw `vmstat ` data using gnuplot
This will log your internet download speed.
You can run
gnuplot -persist <(echo "plot 'bps' with lines")
to get a graph of it.
I've been auto-generating some complex GnuPlots; with multiplots the first plot of each group needs to be a 'plot' whereas the others need to be 'replots' to allow overplotting/autoscaling/etc to work properly.
This is used to replace only the first instance of 'replot'.
Useful when you've produced a large file of numbers, and want to quickly see the distribution. The value of y halfway along the x axis is the median. Simple!
Just create the listOfNumbers.txt file with a number on each line to try it out.
