With Bash CtrlL will clear the screen but not scrollback buffer. In the past I have worked around this by using:
tput reset
However I have noticed that this command will not clear the scrollback buffer with Zsh. So, how is it done?

It's remotely possible that there's a bash alias for `tput` (though the bash style tends to be hard-coded escape sequences). Perhaps the `TERM` (and corresponding *reset* differ: some use the hard-reset, some don't). – Thomas Dickey May 03 '19 at 23:13

Works for me, but this depends on the terminal. Which terminal emulator are you using? Do you have the same problem in other terminal emulators? Are you using an interface such as screen or tmux? Do you, at any point (e.g. in your zsh configuration, or in your `.profile`, or in your terminal configuration, or anywhere else), change the value of the `TERM` environment variable? – Gilles 'SO- stop being evil' May 04 '19 at 23:21

function clear-scrollback-buffer {
# Behavior of clear:
# 1. clear scrollback if E3 cap is supported (terminal, platform specific)
# 2. then clear visible screen
# For some terminal 'e[3J' need to be sent explicitly to clear scrollback
clear && printf '\e[3J'

zle && zle .reset-prompt && zle -R
}
zle -N clear-scrollback-buffer
bindkey '^L' clear-scrollback-buffer
clear and zle .reset-prompt && zle -R are added to make sure it works for multiline prompts, which is important.

That's for iterm2, while OP is asking about VTE (the two do not behave the same). – Thomas Dickey Jul 20 '19 at 15:17

@ThomasDickey Yes, you're right. The sequence code is for xterm, not VTE. I missed it. – Simba Jul 20 '19 at 15:42
