Mausberry Shutdown Script Doesn't Save Metadata

lostless

@cyperghost getting all philosophical on me? Lets not derail to far, but i think i clearly under stand the difference between obsession and passion. Obsession is passion gone too far, when there is no need to keep going. When all is lost, yet you continue. When the path has reached its end and you gone over the cliff. I think I'm done.................. :/

cyperghost

@lostless You're right. You may help us in outfinding the best sleeptimer :) That's your passion :) you can also use floating number like 2.5 to pause

You guys are awesome. I haven't tried 1.5b (adding proper exit out of the loop) on my own system yet, but it sounds like you got it working. I hate not being home today to participate more. :) Thanks everybody! When I get a chance, I will put it into place and report back my own findings.

bug report

Our method to kill the command placed on the 4th line of /dev/shm/runcommand.info fails to kill ScummVM emulator. This is why:

[prompt]$ sed -n 4p /dev/shm/runcommand.info
bash /home/meleu/RetroPie/roms/scummvm/+Start\ ScummVM.sh "ft"

Then our approach kills bash processes.

I'm currently trying to find a strong solution. Will post it soon...

Can you guys test this one? Let's call it v1.7:

#!/bin/bash -x
# Before using this script you need to install inotify-tools:
#
#    sudo apt-get install inotify-tools
#
# I'm just trying to help with the script logic here.
# I DON'T HAVE A MAUSBERRY AND DIDN'T TEST THE GPIO STUFF HERE!

I did a trick for debugging, then if this script doesn't work, please perform this command:

grep 'rc\.local' /var/log/syslog > debug.log

It creates a file named debug.log paste its conten in ghostbin.com or something similar.

lostless

@meleu still did not work. I did the grep thing and can't find the syslog directory to find debug.log. also i don't have the /sys/class/gpio/gpio$GPIOpin1 directory. not sure if thats useful, but trying to help.

meleu

@lostless please, paste here the output of these commands:

ls -l /var/log/syslog

and

ls -lah /sys/class/gpio/*

first

-rw-r----- 1 root adm 2281836 Jul 29 03:38 /var/log/syslog

second

@lostless

now these:

cd
grep rc.local /var/log/syslog* > debug.log
ls -l debug.log

lostless

-rw-r--r-- 1 pi pi 16656 Jul 29 03:44 debug.log

i found a debug.log in the home (~) directory

meleu

@lostless open this file on your Windows (I'm assuming you're using Windows), select all text and paste on ghostbin.com

lostless

@meleu nope mac. I can boot into windows if need be.

meleu

@lostless nop, I just need you to copy the entire file

lostless

@meleu
its just

/var/log/syslog:Jul 23 06:28:29 genepi systemd[1]: Starting /etc/rc.local Compatibility...
/var/log/syslog:Jul 23 06:28:29 genepi systemd[1]: Started /etc/rc.local Compatibility.

over and over with different dates and times. nothing else.

meleu

@lostless now I need you to do the same thing for /etc/rc.local and /etc/switch.sh (the last one is supposed to be my v1.7 script, but please, paste it on ghostbin so I can really check if everything is fine)

lostless

/etc/rc.local
https://ghostbin.com/paste/goucc

/switch.sh
https://ghostbin.com/paste/5agap

meleu

@lostless

ls -l /etc/switch.sh

lostless

@meleu said in Mausberry Shutdown Script Doesn't Save Metadata:

ls -l /etc/switch.sh

-rwxrwxrwx 1 root root 1889 Jul 29 02:42 /etc/switch.sh

meleu

@lostless
damn! I'm not getting what's wrong! Let's try this:

sudo bash -x /etc/switch.sh & 2> /home/pi/script-debug.txt

And then press the f%#&ing button. Pretty please... :)

It should turn off your pi...

@meleu aaaaaaaaaaaaaannnnnnnddddd...................

...........NO GOOD. >:( sorry man.
