Spy audio, it only records if detects a sound or noise
It find out the mic recording level at the moment of run the command and if a noise level is higher it starts to record an mp3 file. The resulting file will have only the sounds not the silences.

Prevent overwriting file when using redirection
If you set noclobber to on, bash won't allow redirection to overwrite existing files . $ set -o noclobber command turn the option on (default it s off ) . You can still append information but not overwrite the file .to turn it back off use : $ set +o noclobber . I use it because i overwrite a file by accident , after thought , content of the file was very important , creating a one more file mean nothing for my hard disk (we are not anymore on the 64 k memory time) , but content of file is far much important . What we call exeprience :(

Download an entire static website to your local machine
Very nice command when you want to download a site locally to your machine, including images, css and javascript

View facebook friend list [hidden or not hidden]
There's no need to be logged in facebook. I could do more JSON filtering but you get the idea... Replace u=4 (Mark Zuckerberg, Facebook creator) with desired uid. Hidden or not hidden... Scary, don't you?

Fetch every font from dafont.com to current folder
Requires aria2c but could just as easily wget or anything else. A great way to build up a nice font collection for Gimp without having to waste a lot of time. :-)

Retry the previous command until it exits successfully

tail: watch a filelog
-f file(s) to be monitorized -n number of last line to be printed on the screen in this example, the content of two files are displayed

preserve disk; keep OS clean
if you use disk-based swap then it can defeat the purpose of this function.

Easily find latex package documentation
If the pdf/dvi/etc documentation for a latex package is already part of your local texmf tree, then texdoc will find and display it for you. If the documentation is not available on your system, it will bring up the package's webpage at CTAN to help you investigate.
