When doing qemu dev, I frequently run it in a tmux, and start it with
'-nographic' which gets you a single stream with both serial and monitor in it;
alternatively you can get one pane with the serial output and one with the
monitor, that takes a little more setup;
anyway, then I can do :
tmux -L $SESS send-keys -t srcqemu "cd /mnt" enter
and have a wait function that waits until a string is displayed:
# pane string command
function waitstr {
PANE=$1
STR=$2
CMD="$3"
until [ -n "$(tmux -L $SESS capture-pane -p -t $PANE | grep "$STR" )" ]; do
$CMD
sleep 1
done;
}
so do:
waitstr srcqemu "root@localhost" "sleep 1"
it feels like it should be fairly easy to wrap some of those for tests.
(Beware the 'send-keys' command is a bit touchy about what strings it takes,
but it has some flags to help).
