I have this code:
if [ -f "/mnt/usb/test/linuxConfig.json" ]
then
echo "usb på plats"
What I want is when the file is found ( aka the usb is mounted) to set a variable as true.
I want to write a script that checks if the the usb is mounted and in case is not to try to mount it and if it fails to reboot the pi.
I need the variable to be true or false since I want to use a sleep command as well.
I don't really see where you want to use that variable as you could easily do everything you might want to do in the correct if-then-else branch:
if [ -f "my/file" ]; then
echo 'Filen finns tillgänglig / the file is available'
else
echo 'Filen är inte där / the file is not there'
mount /mnt/something || { sleep 120; reboot; }
# or ... || shutdown -r +2 'Rebooting due to failed mount'
fi
To use a "boolean" variable:
found=0
[ -f "my/file" ] || found=1
if (( !found )); then
# file was not found
else
# file was found
fi
You can use any nonempty value as "true":
if [ -f /mnt/ust/test/linuxConfig.json ] ; then
var=1
fi
if [ "$var" ] ; then
echo Var is true
else
echo Var is false
fi
