multitail/ssh leaves processes hanging around after exit

Question

I'm using multitail via SSH to filter log output on a number of servers like so:

multitail -L "ssh foo.bar.com tail -n 0 -q -F /var/log/out.log | grep match" 

This works great, however when multitail exits multiple processes are left hanging around -- three to be exact: bash, tail, and grep.

How can I force multitail (or more likely ssh) to terminate child processes and exit?

You need to use the -t option with ssh. See the following link:
