[OT] need crontab help

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



Hi all,

There is a java app that writes directly to the pulseaudio MASTER channel at full volume twice a day. I'm pretty sure the neighbors hear it. My idea is to use crontab to run at 12:59 Monday-Friday. It waits 59 seconds, mutes the audio, waits 6 more seconds and unmutes the audio. From the command line it works. I can't make it work using crontab. It does show up in the syslog.

This is in my /etc/crontab (all on one line)

59 12  *  * 1-5 root test -x /usr/local/bin/mute && \
( \
   /bin/sleep 59 ; \
   /usr/local/bin/mute ; \
   /bin/sleep 6 ; \
   /usr/local/bin/unmute \
)

This is /usr/local/bin/mute and unmute:

sink=$(pactl info | grep "Default Sink" | cut -d' ' -f3)
pactl set-sink-mute "$sink" 1 (unmute uses 0)


Anybody explain why this doesn't do what I intend?

Thanks,
Mike Wright
