fsdiff is a very simple tool used to compare recursively the filesystem directory and file structure.
It does not only perform a quick (shallow) comparison using os.stat (stat system call), it also compares
the contents of the files.
In case they differ, it displays a brief summary report. It is also installed as a Python packaged, so it can be used likewise.
Example run:
sudo fsdiff rootfs bootfs
For a more detailed investigation a deep checking tool like diffoscope or Beyond Compare, may be used.
To install you need to run pip3 install fsdiff, with either super
user privileges or with the --user flag.
Note: Python 3.x is required, a few new language features are used, like subprocess.run method as well as the cache
clearing from the directory compare library. It also needs to be run with super user privileges.
