I think this makes a bit more sense. I think the original reasoning for -x/--cksum was to match -x/--device in dbgrbyd.py, but that flag no longer exists. This could go all the way back to matching --xsum at some point, but I'm not sure. Common hash related utils, sha256sum, md5sum, etc, use -c/--check to validate their hash, so that's sort of prior art?
