Nice one. Can you explain the start of the perl regexp ? :


And at the end, the ( ) are not needed IMHO.

Cheers, sputnick.

Hi Sputnik, that's a positive lookbehind assertion. The regex only matches "/dyn/str_..." if it's preceded by a double quote character.

By the way, wizel, that regex can be made shorter. This is what I would use:

display http://dilbert.com$(curl -s dilbert.com|grep -Po '(?<=")/dyn/str_strip(/0+){4}/.*strip.gif')

thanks sightmillion, your're right.

I was wondering what the Dilber site used to tag/identify the strip.

So I opted for the "safest" approach, but thing your proposal works OK.

Comment by wizel 311 weeks and 3 days ago

Thanks eightmillion.

The website made changes.

I have successfully tested :

display http://www.dilbert.com/$(curl -s dilbert.com | grep -Po '(?<=")/dyn/str_strip(/0+){4}/.*strip.[^\.]+\.gif')
Comment by sputnick 311 weeks and 3 days ago

Another way :

display http://dilbert.com$(curl -s dilbert.com|grep -Po '"\K/dyn/str_strip(/0+){4}/.*strip.[^\.]*\.gif')
Comment by sputnick 311 weeks and 3 days ago

sputnick, I've corrected with you version and added your name in the comments.

If you don't feel OK, pls let me know.

Comment by wizel 311 weeks and 2 days ago

And for your crontab :

30 08 * * 1-5 DISPLAY=:0 display http://dilbert.com$(curl -s dilbert.com | grep -Po '"\K/dyn/str_strip(/0+){4}/.*strip.[^\.]*\.gif')

Like mine, you will have monday to friday the image shown on your desktop at 08:30 AM

Comment by sputnick 311 weeks and 1 day ago

Here's one for Doonesbury. The regex is easier for this site:

display -title 'Doonesbury' $(curl -s http://www.doonesbury.com/strip/dailydose/index.html | grep -Eow -m 1 'http://images.ucomics.com/comics/db/[0-9]{4}/db[0-9]{6}\.gif')

The grep -w and -m 1 options are unnecessary but I thought might make it a bit more robust.

Comment by johnraff 310 weeks and 6 days ago

This works on OSX

open $(curl -s dilbert.com | grep -o 'http://dilbert.com/dyn/.*strip.gif')
