I'm currently writing a simple bash script for recording a streaming radio stream. The logistics of getting into work and getting set up mean that I miss about 30 minutes of my favourite breakfast show, so I'm writing this script with the intention of putting it on a cron schedule on my work machine to start recording about 15 minutes before I get to work.
The following excerpt from the script does not work:
echo ${FILEFULLPATH} | xargs -t screen -dmS ${STATION_NAME}Stream mplayer ${STATION_URL} -dumpstream -dumpfile
However, running the xargs -t output works perfectly - screen -ls shows the screen and screen -r shows that the command is indeed running. This is that output command:
screen -dmS RadioXStream mplayer http://radiostream.net/ -dumpstream -dumpfile ~/radio/radiostream_06102015-1316.mp3
I've used set -x and everything looks fine. When I run screen -ls after running the script, the screen that is supposed to have created does not exist.
I based this command on an earlier script I wrote for a Minecraft server, with the only main difference being that I use xargs here for the filepath, as it was wrapping a relative directory in quotes, e.g '~/radio/file.mp3'
