sort -R randomize the list. head -n1 takes the first.

Access a random news web page on the internet. The Links browser can of course be replaced by Firefox or any modern graphical web browser.

I tried a few curses based mp3 players for playing back choir practice songs for my wife. Unfortunately none of the ones I tried were capable of scrubbing a track. Firefox saves the day.

Just feed classical duckduckgo request replacing the "!" for the bang by a "-" (ie. "ddg -gi mickey mouse") and the result will be opened in w3m (think of installing w3m-img for image support in xterm or tty) To put it in the .bashrc, remove the "\" that escapes the "!".

also use: update-alternatives --config gnome-www-browser

More compact and direct.

KISS To get a random xkcd comic: xdg-open http://dynamic.xkcd.com/random/comic/

This includes a title attribute so you can see the file name by hovering over an image. Also will hoover up any image format - jpg, gif and png.

My take on the original: even though I like the other's use of -exec echo, sed just feels more natural. This should also be slightly easier to improve. I expanded this into a script as an exercise, which took about 35 minutes (had to look up some docs): http://bitbucket.org/kniht/nonsense/src/7c1b46488dfc/commandlinefu/quick_image_gallery.py

Setting: You have a lot of jpg files in a directory. Maybe your public_html folder which is readable on the net because of Apache's mod_userdir. All those files from the current folder will be dropped into a file called gallery.html as image tags that can be viewed within a web browser locally or or over the Internet. Original: find . -iname "*.jpg" -exec echo "<img src=\"{}\">" >> gallery.html \;

Continue with: killall -CONT -m firefox Suspends all Firefox Threads. Results in Zero CPU load. Useful when having 100+ Tabs open and you temporarily need the power elsewhere. Be careful - might produce RACE CONDITIONS or LOCKUPS in other processes or FF itself. matching is case sensitive.
