Short and sweet command. This command is also useful for other information such as what IP address a particular user logged in from, how long had they been logged in, what shell do they use.
Thanks for the submit! My alternative produces summaries only for directories. The original post additionally lists all files in the current directory. Sometimes the files, they just clutter up the output. Once the big directory is located, *then* worry about which file(s) are consuming so much space.
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.

A slightly shorter version. Also doesn't put a return character at the end of the password
If you know the URL of a file on a SharePoint server, it's just a matter of logging in with your AD credentials to get the file with cURL
-d Draw the filename at the top-left of the image

This command will show images in subdirectories as well.
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).
sudo apt-get install libnotify-bin
simple function i found somewhere to open vim help page from the shell

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.
