How can I clear the scrollback buffer in konsole from bash?

Question

I'm a heavy bash user and konsole is my preferred environment. I know I can use the keyboard command ctrl+shift+x to clear the scrollback buffer, but there's certain points in my scripts where I would like that to occur. How can I clear konsole's scrollback buffer using the command line, bash, or any other shell?

This will do it:

echo -e "\e[3J"

Found here. Works in regular xterm too.

didn't work for me on SUSE in a xterm with bash shell. – djangofan Mar 19 '11 at 20:00

I liked echo -ne "\e[3J" better as it avoids printed line-break. – Patrick B. Mar 22 '12 at 12:01

@PatricB.: true, though in this context, I'm expecting him to incorporate it into a script – retracile Mar 22 '12 at 16:26
@PatrickB. Thanks for the reminder on the -n. :) – Joshua K Jan 21 '13 at 20:53

@SandeepDatta: It works with konsole 4.14.3 on Fedora 20; it doesn't clear the screen--it clears the scrollback buffer. – retracile Apr 10 '15 at 18:36

As an extension to this answer, I aliased this to the clear command (`alias clear="clear && echo -e '\e[3J' && clear"`) so my screen actually clears now. – BrockLee Sep 25 '15 at 15:21
