A while back, on an old installation, I had installed a package that allowed me to view and delete metadata from images. I'm fairly certain the syntax was as follows
To display the metadata in an image
mat -d <name of image>
To clear metadata from an image
mat -c <name of image>
I have reinstalled my computer, but I can't seem to remember what the package name is. I'm aware that there are alternatives (exiftool or something), but it's really bothering me that I can't remember what it was called. If anyone knows what package I'm talking about, I'd greatly appreciate it!
