I have a bunch of pendrives with live Linux ISOs loaded onto them and I would like to check one if it is persistent. Rebooting is not an option right now (system rescue).

Is there a simple command or utility to check if the current pendrive Linux installation is persistent on the pendrive?

On the drive, look for the file casper-rw. That is the persistence file for Ubuntu drives.
