Take a screenshot and upload to imageshack.us, then copy the link to clipboard. Allow one argument, use s for selection, a integer for amount of seconds to wait. (Can't do both)

screenshot.sh

#!/bin/bash
rm screenshot.png -f
if [ $# -ne 0 ]
	then
	if [ "X$1" = "Xs" ]
		then
			scrot screenshot.png -s
		else
			scrot screenshot.png -d $1
		fi
	else
		scrot screenshot.png
	fi
curl -H Expect: -F fileupload="@screenshot.png" -F xml=yes -# "http://www.imageshack.us/index.php" | grep image_link | grep -o  http[^\<]* | xclip -selection clipboard
