very nice and funny..Thank u for made this easter happy!
Please don’t mention Ubuntu or other distro names unless the feature is specific to that particular distro. It confuses less experienced users. I think Gnome is available on at least a couple of Distros! ;^)
“# aptitude -v -v -v -v -v moo”
Can also be written as:
“# aptitude -vvvvv moo”
This applies to a basic series of command line options in most Linux applications. There are exceptions such as options that require additional parameters.
Thanks for the list! I hope there are more!
hey dude,nice i like the fish
Good one!!!!
Very cool. Thanks!
the fish gets annoying after a while, how do you make it go away?
Please advice how to kill the fish.
You can kill the fish by doing this from the terminal:
killall gnome-panel
But please, let the fish live. It is easter 😉
“Please advice how to kill the fish.”
“Catch” the fish! Just click on the fish and they “swim” off the screen! Nice!
to kill the fish just wait for 5 mins automatically it will disapperies other wise just try to click on the fish.. it will go away…….. 🙂
Oh no, please, don’t kill the fish, let it live! ))
