Simple start/stop shell-script

Nothing fancy but maybe useful for someone.

#!/bin/bash

   if [ -z $PID ]; then
      echo "Subsonic is not running."
      exit 1
   else
      echo -n "Stopping Subsonic.."

Here's one that can start/stop/restart/status without using terminal commands. Requires the zenity package, which I think is fairly common.

I haven't figured out a good way to get a sudo prompt if needed, although another script could ask for sudo password and then pass it to this script as described at http://techrepublic.com.com/5208-12853- ... ID=2541628

         kill $PID; sleep 1
         get_pid

      echo "# Subsonic stopped."; sleep 1

I haven't figured out a good way to get a sudo prompt if needed

How about gksu / gksudo?

I updated my script recently (using the PID file now and fixed some other quirks), I'll post it soon.

[WannaBeGeekster]

I would still be curious to see the changes you have made? Did you just re-edit your last post and I didn't notice?

Thanks!

To future Googlers, I found this form looking for a simple way to manually start and stop the Subsonic service on Linux. The easiest way I found to do that is:

sudo service subsonic restart
sudo service subsonic start
sudo service subsonic stop
sudo service subsonic status


This works like a charm on my 32-bit Ubuntu 11.10, hope it helps.

[ytechie]

Yup. That is how I run my subsonic services.

This future Googler thanks you in the past!
