how to reset terminal?
 

After i'm running a program in C, my terminal show some wied characters and it hangs up.
I know there was a key combination to reset it in cases like this, but i can't remeber it and couldn't find it on google either. Anyone knows ?

Thanks !

Type in the "reset" command. If this is a terminal program like konsole, you can resize it a bit then to get rid of the weird characters.

Interrupt using Ctrl + C, then stty sane

solved it, thank you!
