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

    @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
