I’m looking for a command line tool to check if files are the same or not, I know there are “fc
” and “comp
” but I’m not sure which is better or if they are safe or not.
I have different files in different formats (txt, kdbx, keyx, png, rar) so I want a tool that can check all formats even KeePass database (kdbx). I’m also thinking about hash comparison (checksum), but I’m new to these things.
My goal is to use that command line before backing up to ssd, I want to avoid unnecessary writes by skipping similar files, because Robocopy/fastcopy/terracopy can’t do that, they only check date and size and timestamp.
