Make sure a script is run in a terminal.

If your script needs to be run in a terminal, this line at the top will stop it running if you absent-mindedly double-click the icon, perhaps intending to edit it. (Of course this won't help with scripts that run in the background.)

Pronounce an English word using Merriam-Webster.com

Updated to the new version of the MW webpage (seems MW does not use cougar anymore, so the other commands do not work nowadays), and using Xidel to parse the page with a html parser instead regex. Example usage: pronounce onomatopoetic I'm not sure how well Xidel works with binary streams (although it seems to work great in tests), so using wget to download the actual wav file might be safer, i.e.: pronounce(){ wget -qO- $(xidel "http://www.m-w.com/dictionary/$*" -f "replace(css('.au')[1]/@onclick,\".*'([^']+)', *'([^']+)'.*\", '/audio.php?file=\$1&word=\$2')" -e 'css("embed")[1]/@src') | aplay -q;} Xidel is not a standard cli tool and has to be downloaded from xidel.sourceforge.net

tcpdump from src to dst

Redirect tar extract to another directory

The command extracting the tar contents into particular directory ...

dd with progress bar

piping through 'pv' shows a simple progress/speed bar for dd. This is a replacement for my otherwise favorite 'while :;do killall -USR1 dd;sleep 1;done'

What is my public IP-address?

Very effective, use only DNS protocol. The @ part is optional if you already set opendns servers as default ns servers.

Find files and calculate size of result in shell

Use find's internal stat to get the file size then let the shell add up the numbers.

dump 1KB of data from ram to file

Delete Empty Directories

Deletes empty directories and prints an error if directory is not empty.
