How to list pathname of all files using adb
i found a workaround resolution of mounting the device using adbfs-rootless.

The process is simple.  Install the package which is easily build-ed with the two packages from normal distro repositories(the the package's readme):

$ sudo apt-get install libfuse-dev android-tools-adb


then mount with:

$ adbfs ~/mnt


Once mounted the find command from the PC can be used to process the files.
