Psst. Open beta.

Wow, didn't really expect you to read this far down. The latest iteration of the site is in open beta. It's a gentle open beta-- not in prime-time just yet. It's being hosted over at UpGuard (link) and you are more than welcome to give it a shot. Couple things:

  • » The open beta is running a copy of the database that will not carry over to the final version. Don't post anything you don't mind losing.
  • » If you wish to use your user account, you will probably need to reset your password.
Your feedback is appreciated via the form on the beta page. Thanks! -Jon & CLFU Team

View the newest xkcd comic.

View the newest xkcd comic.

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)';}

Alternatives

There are 2 alternatives - vote for the best!

Terminal - Alternatives
eog `curl -s http://xkcd.com/ | sed -n 's/<h3>Image URL.*: \(.*\)<\/h3>/\1/p'`
wget `lynx --dump http://xkcd.com/|grep png`
curl -s 'xkcd.com' | awk -F\" '/^<img/{printf("<?xml version=\"1.0\"?>\n<xkcd>\n<item>\n <title>%s</title>\n <comment>%s</comment>\n <image>%s</image>\n</item>\n</xkcd>\n", $6, $4, $2)}'

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

xkcd() { wget -qO- http://xkcd.com/ | 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.

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

Know a better way?

If you can do better, submit your command here.

What others think

How do you execute it? I got this error:

local: 1: ?>: bad variable name

when I executed it like this:

local f=$(curl -s http://xkcd.com/);display $(echo "$f"|grep -Po '(?<=")http://imgs.xkcd.com/comics/[^"]+(png|jpg)');echo "$f"|awk '/<img src="http:\/\/imgs\.xkcd\.com\/comics\/.*?" title=.*/{gsub(/^.*title=.|".*?$/,"");print}';
Comment by andresmh 366 weeks and 4 days ago

You execute it by pasting in the command as is on the command line (which defines a function called xkcd). Then you use it by simply writing "xkcd" on the command line.

Comment by anders 366 weeks and 4 days ago

aha! thanks! :) how do you set it so it's always available, perhaps with a keyboard shortcut

Comment by andresmh 366 weeks and 4 days ago

You can make it always available by pasting it in your .bashrc file.

Comment by eightmillion 366 weeks and 4 days ago

Remember this does not work on ZSH for some reason.

Comment by matthewbauer 366 weeks and 3 days ago

Zsh doesn't allow declaring a variable local and assigning it at the same time, whereas bash does. This function can be made to work with zsh by separating the declaration and assignment like this:

xkcd(){ local f;f=$(curl -s http://xkcd.com/);display $(echo "$f"|grep -Po '(?<=")http://imgs.xkcd.com/comics/[^"]+(png|jpg)');echo "$f"|awk '/<img src="http:\/\/imgs\.xkcd\.com\/comics\/.*?" title=.*/{gsub(/^.*title=.|".*?$/,"");print}';}

And the same for the random version:

xkcdrandom(){ local f;f=$(wget -q http://dynamic.xkcd.com/comic/random/ -O -);display $(echo "$f"|grep -Po '(?<=")http://imgs.xkcd.com/comics/[^"]+(png|jpg)');echo "$f"|awk '/<img src="http:\/\/imgs\.xkcd\.com\/comics\/.*?" title=.*/{gsub(/^.*title=.|".*?$/,"");print}';}

lynx --dump --source http://www.xkcd.com | grep `lynx --dump http://www.xkcd.com | egrep '(png|jpg)' | awk ' { print $0 } '

Comment by solarislackware 365 weeks and 5 days ago

Debian doesn't compile grep with the '-P' option; I've altered your command to use 'pcregrep' instead, which will work (I did have to use apt-get to install pcregrep).

xkcd(){ wget -qO- http://xkcd.com/|tee >(feh $(pcregrep -oo '(?<=")http://imgs[^/]+/comics/[^"]+\.\w{3}'))|pcregrep -o '(?<=(\w{3})" title=").*(?=" alt)';}
Comment by bartonski 357 weeks and 3 days ago

Thanks bartoniski. I usually try to include a version that doesn't use Perl compatible regexs, but didn't for this command. Grep's about the first thing I replace when I install Debian.

Comment by eightmillion 357 weeks and 3 days ago

A version that works in zsh and takes args for numbered comic, random comic, or leave blank for newest comic:

xkcd() { local comic="$1"; local xkcdurl; if [[ $comic == "random" ]]; then xkcdurl="http://dynamic.xkcd.com/comic/random/"; else xkcdurl="http://xkcd.com/${comic// /+}"; fi; wget -qO- ${xkcdurl}|tee >(feh $(grep -Po '(?<=")http://imgs[^/]+/comics/[^"]+\.\w{3}'))|grep -Po '(?<=(\w{3})" title=").*(?=" alt)';}
