Imagine that you are waiting for marks from exam. Lecturer is going to publish them on his website, but you don’t know when.
I’ve created following script, because I don’t like pressing F5 for hours 
You have to provide address of website, and if website changes, script will open firefox and show notification.
1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 | #!/bin/sh # Wojtek Jamrozy www.wojtekrj.net if [ $# != 1 ]; then echo "usage: $0 <url of website> " exit 1 fi hash=`wget -q -O - $1 | md5sum` while [ 1 ]; do if [ "`wget -q -O - $1 | md5sum`" != "$hash" ]; then firefox $1 notify-send "Change on the website $1" exit 0 fi echo "Nothing has changed" sleep 120 done |
