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.

Just a simple way without the need of additional tools. Of course, replace eth0 with your IF.

Newer versions of the flashplayer browser plugin delete the tmp flash video immediately after opening a filehandle to prevent the user from "exporting" the video by simply copying the /tmp/FlashXYZ file. This command searches such deleted flash videos and creates symbolic links to the opened filehandle with the same name as the deleted file.

This allows you to play your flash-videos (from e.g. youtube) with e.g. mplayer or copy the buffered video if you want to keep it.

countbraces () { COUNT_OPENING=$(echo $1 | grep -o "(" | wc -l); COUNT_CLOSING=$(echo $1 | grep -o ")" | wc -l); echo Opening: $COUNT_OPENING; echo Closing: $COUNT_CLOSING; }

This function counts the opening and closing braces in a string. This is useful if you have eg long boolean expressions with many braces and you simply want to check if you didn't forget to close one.

Sometimes you need a simple server which listens on a port and prints out received data.

Example: Consider you want to know, which data is posted by a homepage to a remote script without analysing the html code! A simple way to do this is to save the page to your computer, substitude all action="address" with action="localhost:portnumber", run 'ncat -l portnumber' and open the edited page with your browser. If you then submit the form, ncat will print out the http-protocol with all the posted data.
