I'm trying to make a service in Automator to run a program on my usb key (to run as a right click service).
This is the bash shell script I need to run
diskutil unmount /Volumes/KINGSTON
fatsort -f -oa /dev/disk1s1
The two paths /Volumes/KINGSTON and /dev/disk1s1 should be treated as variables, being evaluated by Automator.
I get the first one with "Get selected Finder elements" and I put on the shell script as $1
I.E.
diskutil unmount $1
But I don't know how to get the /dev path
