Random Cyanide and Happiness comics from explosm.net. I use this command http://www.commandlinefu.com/commands/view/3477/random-xkcd-comic and update it for explosm.net

--edit : modification for *.jpeg files + guest authors

KISS

To get a random xkcd comic:

xdg-open http://dynamic.xkcd.com/random/comic/
xkcd() { wget -qO- http://xkcd.com/ | sed -n 's#^<img src="\(http://imgs.[^"]\+\)"\s\+title="\(.\+\?\)"\salt.\+$#eog "\1"\necho '"'\2'#p" | bash ; }

This function displays the latest comic from xkcd.com. One of the best things about xkcd is the title text when you hover over the comic, so this function also displays that after you close the comic.

To get a random xkcd comic use the following:

xkcdrandom() { wget -qO- http://dynamic.xkcd.com/comic/random | sed -n 's#^<img src="\(http://imgs.[^"]\+\)"\s\+title="\(.\+\?\)"\salt.\+$#eog "\1"\necho '"'\2'#p" | bash; }

These are just a bit shorter than the ones eigthmillion wrote, however his version didn't work as expected on my laptop for some reason (I got the title-tag first), so these build a command which is executed by bash.

eog `curl 'http://xkcd.com/' | awk -F "ng): |</h" '/embedding/{print $2}'`
gwenview `wget -O - http://xkcd.com/ | grep 'png' | grep '<img src="http://imgs.xkcd.com/comics/' | sed s/title=\".*//g | sed 's/.png\"/.png/g' | sed 's/<img src=\"//g'`

Output the html from xkcd's index.html, filter out the html tags, and then view it in gwenview.

(echo "plot '-' with lines"; for x in $(seq 1 100); do curl -s "http://ajax.googleapis.com/ajax/services/search/web?v=1.0&q=$(echo $x bottles of beer on the wall|sed 's/ /%20/g')"|sed 's/.*"estimatedResultCount":"\([^"]*\)".*/\1\n/';done)|gnuplot -persist

Will create a graph of the results for "x bottles of beer on the wall".

Requires Gnuplot.

Inspired by an xkcd comic: http://xkcd.com/715/

For sample output see: http://tr.im/xbottlesofbeer

Add an alias to your .bashrc that allows you to issue the command xkcd to view (with gwenview) the newest xkcd comic... I know there are thousands of them out there but this one is at least replete with installer and also uses a more concise syntax... plus, gwenview shows you the downloading progress as it downloads the comic and gives you a more full featured viewing experience.

wget -q http://dynamic.xkcd.com/comic/random/ -O-| sed -n '/<img src="http:\/\/imgs.xkcd.com\/comics/{s/.*\(http:.*\)" t.*/\1/;p}' | awk '{system ("wget -q " $1 " -O- | display -title $(basename " $1") -write /tmp/$(basename " $1")");}'

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:

wget -q http://xkcd.com/ -O-| sed -n '/<img src="http:\/\/imgs.xkcd.com\/comics/{s/.*\(http:.*\)" t.*/\1/;p}' | awk '{system ("wget -q " $1 " -O- | display -title $(basename " $1") -write /tmp/$(basename " $1")");}'

Bulk downloads the comic strip JPG files for the adult cartoon Savitabhabhi, storing each set in it's own folder. Requires manual removal of "non-image" files that maybe created because each series may differ in length. The command can be easily adapted for UNIX flavours. You need to have cURL in your path.

Requires display.

Corrected version thanks to sputnick and eightmillion user.

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

lynx --dump --source http://www.xkcd.com | grep `lynx --dump http://www.xkcd.com | egrep '(png|jpg)'` | grep title | cut -d = -f2,3 | cut -d '"' -f2,4 | sed -e 's/"/|/g' | awk -F"|" ' { system("display " $1);system("echo "$2); } '

Same thing just a different way to get there. You will need lynx

This function displays the latest comic from xkcd.com. One of the best things about xkcd is the title text when you hover over the comic, so this function also displays that after you close the comic.

To get a random xkcd comic, I also use the following:

xkcdrandom(){ wget -qO- dynamic.xkcd.com/comic/random|tee >(feh $(grep -Po '(?<=")http://imgs[^/]+/comics/[^"]+\.\w{3}'))|grep -Po '(?<=(\w{3})" title=").*(?=" alt)';}
