[Solved] in havoc terminal emulator: yes causes broken pipes

Hi patrikg. Yes, I have done an internet search.
Hi jazzbiker. I don't have coreutils loaded. The only  yes  on my system is the busybox applet.

curaga:
That stackoverflow link does look like the most likely explanation. IOW, it's a bug in those two terminals, havoc and weston terminal.

Darn. In that case, I created this trivial wrapper script for yes, which does away with the errors when using tce-load:

--- Code: ---#!/bin/sh
exec /usr/bin/yes "$@" 2>/dev/null
--- End code ---
But that doesn't solve scripts where yes is needed multiple times in same pipeline. Even with the wrapper script, something like this:

--- Code: ---yes "password" | bcrypt somefile
--- End code ---
seems to enter an endless loop, driving CPU usage way up. Workaround for this situation is this kludge:

--- Code: ---i=1
while true; do
echo "password"
[ $i -eq 2 ] && break
i=$(( $i + 1 ))
done | bcrypt somefile

--- End code ---
If I figure out how to properly fix the bug in the terminal emulators, I'll post it here.

Juanito:
Why not file a bug report against weston or havoc?

What if you do it like this:

--- Code: ---echo -e  "password\npassword" | bcrypt somefile
--- End code ---
