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.

    I liked echo -ne "\e[3J" better as it avoids printed line-break.

    @PatricB.: true, though in this context, I'm expecting him to incorporate it into a script

    @SandeepDatta: It works with konsole 4.14.3 on Fedora 20; it doesn't clear the screen--it clears the scrollback buffer.

    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.
