I know about the Linux clear command, but it just moves the previous output from the visible part of terminal window (KDE Konsole). I can still scroll up and see all previous text. Is there similar command that can erase entire content of a terminal window? (Something like clc in matlab.)

true, sorry for that – sivic Aug 9 '11 at 3:29
@wesley not a dupe. – xenoterracide♦ Aug 9 '11 at 4:12
@rozcietrzewiacz: Close but I don't actually think this is a duplicate. The answer is the same, but not the need. – Caleb Aug 9 '11 at 20:01

I'm sure you could make a command with dbus. But there is a shortcut for clear scrollback and reset by default. Ctrl + shift + x.

Yes! Finally an superb answer. Thanks! – sivic Aug 9 '11 at 4:53
Does "Ctrl + shift + x" work only in konsole? – rozcietrzewiacz Aug 9 '11 at 8:11

I don't know. I don't use anything else – xenoterracide♦ Aug 9 '11 at 15:36

reset is enough. No need to explicitly clear scrollback with it.

reset is not working in Konsole – sivic Aug 9 '11 at 17:45

The RIS sequence (\ec) indeed doesn't clear history (Bug 171598), but in KDE 4 there's another sequence that does specifically clear history: \e[3J -- Bug 158235.
