run-shell error on while-loop

[C***@thekyel.com]

I've got a weird issue where running a script with "run-shell" acts differently than running it from my actual shell.

bind-key -n "M-B" run-shell "/bin/bash /usr/bin/test.sh"
#!/bin/bash
lockfile="/tmp/.tmux.lock"
touch "${lockfile}"
tmux choose-buffer "paste-buffer -b '%%' ; run-shell \"rm ${lockfile}\""
while [ -f "${lockfile}" ]
do
sleep 1
done
touch "/tmp/.paste.done"

If I run the script from my shell, it works fine. The lock-file gets created, and then removed. The "/tmp/.paste.done" file is also created.

If, however, I run the script using my key-binding above, I get an error on line 4.
The paste-buffer will paste, but the lock-file is never removed.

One weird thing I've figured out, is that if I remove the while-loop on lines 5-8, the script works no matter how I call it.

Any other thoughts/ideas on how to troubleshoot or debug this?

Your choose-buffer commands will run in the same session as your key
binding but that session's command queue is blocked waiting for the
first run-shell to exit. Bind the key to run-shell -b instead.

tmux 1.9

Hey! works like magic. I guess I thought that if I ran it in the background, that I'd never see the choose-buffer.
Thanks!
