Run the built in PHP-server in current folder
You must have PHP 5.4.0 or later to be able to run the built in server. This web server is designed for developmental purposes only, and should not be used in production. URI requests are served from the current working directory where PHP was started, unless the -t option is used to specify an explicit document root. If a URI request does not specify a file, then either index.php or index.html in the given directory are returned. If neither file exists, then a 404 response code is returned. If a PHP file is given on the command line when the web server is started it is treated as a "router" script. The script is run at the start of each HTTP request. If this script returns FALSE, then the requested resource is returned as-is. Otherwise the script's output is returned to the browser. Standard MIME types are returned for files with extensions: .css, .gif, .htm, .html, .jpe, .jpeg, .jpg, .js, .png, .svg, and .txt. The .htm and .svg extensions are recognized from PHP 5.4.4 onwards.

play high-res video files on a slow processor
Certain codecs in high res don't play so well on my Dell Mini 9. Using this command, I can play just about anything and it keeps the sound in sync to boot!

List top 10 files in filesystem or mount point bigger than 200MB
Specify the size in bytes using the 'c' option for the -size flag. The + sign reads as "bigger than". Then execute du on the list; sort in reverse mode and show the first 10 occurrences.

a shell function to print a ruler the width of the terminal window.
A similar version for Bash that doesn't require cut and shortens the function in a few places. And it uses local variables. (similar to a version by eightmillion in a comment on the another version)

slow down CPU and IO for process and its offsprings.

Tail a log-file over the network
This one is tried and tested for Ubuntu 12.04. Works great for tailing any file over http.

Use top to monitor only all processes with the same name fragment 'foo'
top accecpts a comma separated list of PIDs.

Duplicate installed packages from one machine to the other (RPM-based systems)

clear screen, keep prompt at eye-level (faster than clear(1), tput cl, etc.)
this leaves the cursor at the bottom of the terminal screen, where your eyes are. ctrl-l moves it to the top, forcing you to look up.

Replace 'csv_file.csv' with your filename.
