In this video I cover Linux file system hierarchy. The somewhat loosely followed systems give some standardization to Linux distributions.
Lets look at $ man hier.
You will notice / root which is a must, proc which is a pseudo file systems and some things missing like /dev/shm or shared memory system which is a tmpfs
In this video I use Linux and ImageMagic to strip the location, camera information and other metadata from a jpg image file.
First we look at the image exif and other metadata with strings and identify
Next we strip the date with mogrify strip and diff the identify -verbose between the new and a backup.
Finally I go over mogrify -strip -auto-orient which will keep the proper photo geometry and orientation and we diff the strip difference.
