Launch a command at the end of Linux startup

Instead of running mplayer directly from your start up, I would write a script and run that instead.

Your script would eventually just run the same mplayer command you have given, but before hand you could check that your wifi connection is up and working (maybe by pinging your router), this gives your script control. It could wait until the connection comes up, and then start mplayer.

If you put start the script in something like rc.local, then it will start once on start-up. if you start it from your profile, then it will be started when you login.

Here's an example script which waits until it successfully pings an IP address before starting mplayer.

#!/bin/bash

RouterIP="128.0.0.1"
TimeOut=2
WaitTime=8


echo "Waiting for network connection"
while ! ping -q -c 1 -w $TimeOut $RouterIP > /dev/null
do
  echo Timeout, waiting $WaitTime seconds
  sleep $WaitTime
  echo "Waiting for network connection"
done

mplayer blah blah

You can change the ip address to your routers internal port and correct the mplayer line.

Name it startRadio and make it executable then test it.

`./startRadio

Add it to whichever startup script you want, but redirect stdout and stderr to /dev/null and start it as a background process.

eg.

/path/to/your/script/startRadio >/dev/null 2>&1 &
