Clear scroll back buffer in zsh

In bash you can use ctrl + L to clear the scroll back in the terminal. However in zsh, it doesn't work. So here is a workaround. You can use a control sequence to clear it, and set an alias for that. 


Open your  .zshrc file in the editor.

$ vim ~/.zshrc

And add this to the file.

alias cls='printf "\ec\e[3J"'

Save and reload the terminal: or

    $ source ~/.zshrc


Now when you run the command 'cls', it should clear your terminal with its scroll back buffer. Hope it helps.
