Check These Out

Random quote from Borat -- no html parsing

Turns out smacie.com has a text file containing every single one of the borat quotes, each one on a newline. This makes it very convenient, as this can be done without any sed-parsing, and uses less bandwitdth! Note that borate quotes are quite offensive, much more so than "fortunes-off"!

list files recursively by size

Update your journal

prerequisite: $ mkdir ~/journal

Stream YouTube URL directly to mplayer.

List and delete files older than one year

Check if the files in current directory has the RPATH variable defined

Using gentoo prefix portage I got in a situation where some packages did not contain the needed RPATH variable. This command helped me to find out which ones I should recompile

Create and access directory at the same time

Create and access directory (edited)

Which processes are listening on a specific port (e.g. port 80)

swap out "80" for your port of interest. Can use port number or named ports e.g. "http"

exec chmod to subfiles

Using `-exec cmd {} +` causes find to build the command using all matching filenames before execution, rather than once per file.
