asterisk users - Sep 2009 - running a asterisk -rx command in bash backgroun

Hello!

I have a very simple bash script:

#!/bin/bash
asterisk -rx "sip show peers" > /var/log/devices

When I run it in bash shell, everything works fine, but if I
background it (by adding & or using bg), nothing appears in the
/var/log/devices file.

Any reason for this behavior or help would be great!

Thanks,
Elliot

Even though it doesn't need it, it seems to be expecting keyboard input, 
so it stalls. Odd, but I'm sure there's a reason for it.

Try this:

   rasterisk -x 'sip show peers' > /var/log/devices < /dev/null
&

You may now have lots of processes stuck, waiting, so best run

   ps ax | fgrep asterisk

to check.
