How do I completely clear a terminal window [duplicate]
Solution 1:
If you type reset it'll totally reinitialize your terminal instead of clearing your screen. You can setup a keyboard shortcut for that.
printf "\033c" also work well and takes less time.
You can alias it by alias cls='printf "\033c"' too. Now when you type cls terminal should get cleared.
