Setting the acpi wakeuptime manually via script
There are problems with setting the wakeuptime of my pc via the buildin mythtv functionality. I really don't know why. If set the wakeuptime manually in acpi, it works. So I made this script, which runs every five minutes (see Cron):
It comes in two parts
set_wakeuptime_via_mythshutdown.sh
Extracts the string for the next wakeuptime out of the mythshutdown command:
#!/bin/bash
echo "MYTH WAKEUP ----------------------------------"
SHUTDOWN="$(mythshutdown -t -v timestamp | grep "wakeup time given" | cut -d " " -f 8 | sed -e 's/T/ /')"
echo $SHUTDOWN
/root/bin/set_wakeuptime.sh "$(date --date "${SHUTDOWN}" '+%s')"
echo "RTC ----------------------------------"
cat /proc/driver/rtc
echo "WAKEALARM ----------------------------------"
cat /sys/class/rtc/rtc0/wakealarm
set_wakeuptime.sh
#!/bin/bash #$1 is the first argument to the script. It is the time in seconds since 1970 #this is defined in mythtv-setup with the time_t argument echo 0 > /sys/class/rtc/rtc0/wakealarm #this clears your alarm. echo "$1" > /sys/class/rtc/rtc0/wakealarm #this writes your alarm. echo "$(cat /proc/driver/rtc)"
Mythtv shutdown check script
As my mythtv box is not only for using mythtv, but also for browsing in the internet, playing music via rhythmbox, I also have to check, if these programs are actually running or not. It also checks for ANY logged in Users EXCEPT the one using the actual mythtv box (:0). So if you are logged in, and don't use any of the listed programs, the box will shutdown.
#!/bin/bash
#
# MythShutdownCheck
#
# checks to see if any other user is
# logged in before idle shutdown
#
# returns "1" if yes, stopping shutdown
# returns "0" if ok to shutdown
#
reset() {
echo Resetting mythtv shutdown timer. Going on ...
exit 1
}
ready() {
echo System ready for shutdown.
exit 0
}
echo This is script $0.
echo ... checking users logged in.
if last | grep still | grep -v ":0" # check for active *ANY* login?
then
echo ... some users are logged in ... continuing.
reset
else
echo ... checking for tv_grab_de_prisma process
if ps x -u mythtv | grep -v grep | grep tvm2xml_auto.sh
then
echo tvm2xml_auto process is still running ... continuing.
