I’ve been using Linux for decades and, although the command line is second nature to me, I still opt to use GUI tools because they tend to be far more efficient than their terminal-based counterparts.

If you’re tired of having to jump through hoops to open files with sudo privileges in the GNOME File Manager, Jack Wallen has just the trick you need. Not all Linux file managers are created equal.

There's a lot to learn about image files on the command line, from verifying file format to finding out where and when photos were taken and maybe even getting an unusual view of what they look like.
