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

Functions: bash sed wget

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'`

Splitting on tags in awk is a handy way to parse html.

Ever wanted to stream your favorite podcast across the network, well now you can.

FOR /f %%g in ('echo %1 ^| iconv -f gbk -t utf-8') DO curl -x proxy:port -u user:pass -d status=%%g -d source="cURL" http://twitter.com/statuses/update.xml

User: MeaCulpa
Functions: iconv

Aside from curl one will need iconv windows binary since windows lacks a native utf-8 cli interface. In my case I need a proxy in China and iconv to convert gbk status string into utf-8. GnuWin32 is a good choice with loads of coreutils natively ported to Windows

"FOR /f" is the solution to pass iconv output to curl.

Instead of having someone else read you the Digg headlines, Have OSX do it. Requires Curl+Sed+Say. This could probably be easily modified to use espeak for Linux.

User: rkulla
Tags: git curl github

In this example we search for 'vim' but vim doesn't have a project on github right now. That's ok, this command still searches for every project that has 'vim' in their description (forks, plugins, etc). To get XML or JSON output just replace 'yaml' in the url with 'xml' or 'json'.

curl http://github.com/api/v1/yaml/git

User: rkulla
Tags: git curl github

In this example 'git' is the user name and the output format is YAML but you can change this to XML or JSON, eg: curl http://github.com/api/v1/json/usernamehere

There's another version on here that uses GET but some people don't have lwp-request, so here's an alternative. It's also a little shorter and should work with most youtube URLs since it truncates at the first &
