[arm-allstar] Power fail script

[David McGough]

Luc,

Make sure the script is set executable once you've copied into the 
destination folder....Like this from a bash prompt:


chmod 755 etc/asterisk/local/check_power_fail.sh

...Then, try to run it.

OK, I paste your script into /etc/asterisk/local/power_fail_check.sh
subsequently how to make it run?

I even made a reboot, and I have an error message? bash: /etc/asterisk/local/check_power_fail.sh: No such file or directory
this commende I use the line 9-Start Bash shell interface

how to start?

Thank you

We could put that out as a script for all and in that case it would get over written in the /usr/local/sbin directory.  That is true of any script you modify. You just need to call it with the full path - /etc/asterisk/local/check_power_fail.sh
