commandlinefu.com is the place to record those command-line gems that you return to again and again.

Delete that bloated snippets file you've been using and share your personal repository with the world. That way others can gain from your CLI wisdom and you from theirs too. All commands can be commented on, discussed and voted up or down.

Follow the Tweets.

Every new command is wrapped in a tweet and posted to Twitter. Following the stream is a great way of staying abreast of the latest commands. For the more discerning, there are Twitter accounts for commands that get a minimum of 3 and 10 votes - that way only the great commands get tweeted.

outputs a f=220Hz guitar string sound (fifth string A)

needs ALSA

pronounce(){ xidel "http://www.m-w.com/dictionary/$*" -f "replace(css('.au')[1][email protected],\".*'([^']+)', *'([^']+)'.*\", '/audio.php?file=\$1&word=\$2')" -f 'css("embed")[1][email protected]' --download - | aplay -q;}

Functions: aplay

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][email protected],\".*'([^']+)', *'([^']+)'.*\", '/audio.php?file=\$1&word=\$2')" -e 'css("embed")[1][email protected]') | aplay -q;}

Xidel is not a standard cli tool and has to be downloaded from xidel.sourceforge.net

Outputs pseudo-random sounds to speakers (stereo mode because of -c 2) when there are any kind of network activity.

Record off the microphone on a remote computer and listen to it live through your speakers locally.

pronounce(){ wget -qO- $(wget -qO- "http://www.m-w.com/dictionary/$@" | grep 'return au' | sed -r "s|.*return au\('([^']*)', '([^'])[^']*'\).*|http://cougar.eb.com/soundc11/\2/\1|") | aplay -q; }

The original was a little bit too complicated for me. This one does not use any variables.

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.)
