When the script is run via cronjob I get the following error(s):

/usr/share/plex-shutdown/plex-shutdown.sh: line 30: ( - )/10: syntax error: operand expected (error token is ")/10")

 + counter=0
 + pending=false
 ++ cat /proc/net/dev
 ++ grep
 ++ awk '{print $2}'
 Usage: grep [OPTION]... PATTERNS [FILE]...
 Try 'grep --help' for more information.
 + upload1=
 + sleep 10s
 ++ cat /proc/net/dev
 ++ grep
 ++ awk '{print $2}'
 Usage: grep [OPTION]... PATTERNS [FILE]...

 + upload2=

I even switch to bash, but only way to get the script working, was to replace $interface by eth0.
The initialisation of $interface is working properly.

++ cat /proc/net/dev
++ grep eth0
++ awk '{print $2}'

My guess is, that somehow the context is lost in the the $() construct. Strangely only when using cron.
