Don't clear screen on mosh connection

[josharian]

Feature request: It'd be nice if the mosh client didn't clear the screen when establishing a connection, or if there was at least an option to disable that behavior. Frequently there's useful context up there I want to have available once I've connected.

Thanks for an awesome tool. :)

Unfortunately we need to know what's in every cell of the screen for mosh to work (just like GNU screen and tmux), so we do have to initialize the terminal to a known state on startup. (And there's no way to sniff out what's already there...)

Sorry!

Bummer.

I wonder if there's a workaround. Would it work to just echo $LINES newlines? The screen would then be clear (and thus in a known state), but the scrollback would be preserved...

Possibly -- you might try that yourself now with a --client= argument to
mosh. (Can be whatever you want followed by "; mosh-client".) That might
meet your needs.

Cheers,
Keith

Good call! Works beautifully. For future spelunkers, here's a little script that works:

#!/bin/bash
for f in `seq 1 $LINES`; do echo; done
exec mosh-client $@

Not all shells set LINES automatically. Better is this:

#!/bin/sh
for f in $(seq 1 $(tput li)); do echo; done
exec mosh-client $@
