This seems to be the baseline unix hexdump. Could it be moved to common/?

[binertia]

This seems to be the baseline unix hexdump. It should probably be moved to common/?

Actually that's is my first thought. What is different between 2 of that is macOS's BSD hexdump don't have verbose tag option (-C | --canonical) like in Linux.

[Managor]

Yeah that's fine. Common is just a fallback directory. Platform specific pages will take priority if a page exists for that platform

I see. hexdump was a part of my previous reorganization efforts where I moved the GNU version to linux/ #16037 (comment)
If you want, you can create pages for all commands that are listed there.
