Know a better way?

If you can do better, submit your command here.

What others think

Maybe anyone could make it "remember" the consoles contents? Should try to open a new shell or somewhat like this?

This leaves the terminal in the color of the last emitted character after you do ^C

@nkoehring: I do not understand. Maybe you need just run `reset`?

@TheGuyOfDoom: Just type `reset` afret ^C.

@nkoehring: Now I get it. It can be done with `screendump` but needs root permission to run it and I am not sure how to run it on ptsX - it is easy on ttyX.

Tou can use sth like:

TEMP_FILE=`tempfile` ; sudo screendump > $TEMPFILE ; screensaver ;

# after ^C



It can be done in script with `trap`. You can make function:

function restore_screen() {




and trap SIGINT liki this:

trap restore_screen SIGINT

If you will do that in script it will restore your tty after ^C.

If you run screen, you could put that into an idle command, and also make it run it in a new screen so that it doesn't mess up your old terminal.


idle 300 eval "screen screensaver" "idle 0"

My .screenrc has this:

idle 300 eval "screen ncmatrix -f -o -u 10" "idle 0"
