Dear Maintainer, I'm trying to work out if a file has changed. The cksum command has a -c option to check that a previously computed checksum is still valid. This does not work with the default algorithm (crc). >From the manual page: "When checking, the input should be a former output of this program" I tried with the following command: $ cksum 20250429_211958724_iOS.jpg |cksum -c With the result: cksum: 'standard input': no properly formatted checksum lines found This invocation should result in an OK message, as is seen if I use the md5 algorithm: $ cksum -a md5 20250429_211958724_iOS.jpg |cksum -c 20250429_211958724_iOS.jpg: OK The info page at https://www.gnu.org/software/coreutils/manual/html_node/cksum-common-options.html specifically states "the default output format" is a supported input format for cksum -c, (as well as the tagged output format which is used when md5 is selected.) This may be an upstream bug (I haven't checked,) but if not it should be fixed (or a note made in the manual page that debian's version lacks the feature.) I also checked this with testing (coreutils 9.7-3), the same bug exists there.
