not the best, uses 4 pipes!

previous version leaves lots of blank lines

Case Insensitive! and Works even if the "<title>...</title>" spans over multiple line.

Simple! :-)

Grab a list of MP3s (with full path) out of Firefox's cache

Ever gone to a site that has an MP3 embedded into a pesky flash player, but no download link? Well, this one-liner will yank the *full path* of those tunes straight out of FF's cache in a clean list.

Shorter and Intuitive version of the command submitted by (TuxOtaku)

Interfaces like lo can be omitted from the beginning, there are probably better ways of doing this, i'm a noob at awk.

Ever gone to a site that has an MP3 embedded into a pesky flash player, but no download link? Well, this one-liner will yank the names of those tunes straight out of FF's cache in a nice, easy to read list. What you do with them after that is *ahem* no concern of mine. ;)

Yet another x11grab using ffmpeg. I also added mic input to the capturing video stream using alsa. Yet I need to find out how to capture audio which is currently playing.

This makes an alias for a command named 'busy'. The 'busy' command opens a random file in /usr/include to a random line with vim. Drop this in your .bash_aliases and make sure that file is initialized in your .bashrc.

Computes a columns average in a file. Input parameters = column number and optional pattern.

This version prints current votes and commands for a user. Pass the user as an argument. While this technically "fits" as a one liner, it really is easier to look at as a shell script with extra whitespace. :)

(Apparently it is too long so I put it in sample output, I hope that is OK.)

Run the long command (or put it in your .bashrc) in sample output then run:

Voila! Your contacts' emails will appear.

Facebook seems to have gotten rid of the picture encoding of emails and replaced it with a text based version making it easy to scrape!

Needs curl to run and it was made pretty quickly so there might be bugs.

You set the file/dirname transfer variable, in the end point you set the path destination, this command uses pipe view to show progress, compress the file outut and takes account to change the ssh cipher. Support dirnames with spaces.

Merged ideas and comments by http://www.commandlinefu.com/commands/view/4379/copy-working-directory-and-compress-it-on-the-fly-while-showing-progress and http://www.commandlinefu.com/commands/view/3177/move-a-lot-of-files-over-ssh

Just refining last proposal for this check, showing awk power to make more complex math (instead /1024/1024, 2^20). We don't need declare variable before run lsof, because $(command) returns his output. Also, awk can perform filtering by regexp instead to call grep. I changed the 0.0000xxxx messy output, with a more readable form purging all fractional numbers and files less than 1 MB.

Although Exim will purge frozen (undeliverable) messages over time, the command "exim -Mrm #id#" where #id# is a particular message ID will purge a message immediately. Being lazy, I don't want to type the command for each frozen message, so I wrote the one-liner to do it for me.

What happens here is we tell tar to create "-c" an archive of all files in current dir "." (recursively) and output the data to stdout "-f -". Next we specify the size "-s" to pv of all files in current dir. The "du -sb . | awk ?{print $1}?" returns number of bytes in current dir, and it gets fed as "-s" parameter to pv. Next we gzip the whole content and output the result to out.tgz file. This way "pv" knows how much data is still left to be processed and shows us that it will take yet another 4 mins 49 secs to finish.

Only need to install Image Magick package.

Display a xkcd comic with its title and save it in /tmp directory

If you prefer to view the newest xkcd, use this command:

I wasn't sure how to display the image, so I thought I'd try xml for a different twist.
