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.

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,…):

replace the "-" by the character you wish. If you have multiple extentions, like jpef, jpg and JPG you could use
mmv "*-*.*" "#1.#3"
If you do not have shuf or an -R option in sort, you can fall back on awk. This provides maximum portability IMO. The command first collects words from the dictionary that match the criteria - in this case: lower case words with no punctuation that are 4 to 8 characters long. It then prints 4 random entries. I decided to print each word on a separate line to improve readability.
The command was too long for the command box, so here it is:
echo $(( `wget -qO - http://i18n.counter.li.org/ | grep 'users registered' | sed 's/.*\<font size=7\>//g' | tr '\>' ' ' | sed 's/<br.*//g' | tr ' ' '\0'` + `curl --silent http://www.dudalibre.com/gnulinuxcounter?lang=en | grep users | head -2 | tail -1 | sed 's/.*<strong>//g' | sed 's/<\/strong>.*//g'` ))
This took me about an hour to do. It uses wget and curl because, dudalibre.com blocks wget, and wget worked nicely for me.
Grabs the current weather in your area (or their best guess of your area). Change the query to your zip code/location (e.g. google.com/search?q=weather+jakarta,+india) to get weather somewhere else. change google.com to google.ca or google.co.uk for metric.

This is an "argument calculator" funktion. The precision is set to 4 and you can use dot (.) or comma (,) as decimal mark (which is great for german users with a comma on the numpad).
view is the command: vi -r which opens a file in read-only mode. The + character jumps to the bottom of the logfile where the most relevant information starts. Other aliases can be created for commonly viewed logfiles.

The large context number (-C 1000) is a bit of a hack, but in most of my use cases, it makes sure I'll see the whole log output.
I needed to get a feel for how "old" different websites were, based on their directories.
