Thanks, nixcraft: Use the shasum command … Side note: this requires lang/perl5.36. openssl(1) is integral to FreeBSD. Example usage: root@macbookpro:/tmp # openssl sha512 ./FreeBSD-14.1-RELEASE-amd64-bootonly.iso.xz SHA2-512(./FreeBSD-14.1-RELEASE-amd64-bootonly.iso.xz)= 0dae82f0d98897dd56657e76aab2d4d3ea3e688f696ed5830de43b122116d6233c64cb357660143e1d439ee2bc0d4c90894b49c13648752206702049792ae798 root@macbookpro:/tmp ..read more

Consider a set of four processes with estimated execution times of 2, 3, 4, and 5 seconds. Each process has two successive executions separated by an input/output operation cycle. The scheduling of the processes is FIFO. Knowing that the response times after the second execution, relative to moment 0, are 30, 28, 20, and 25 seconds, specify the durations of the input/output operations for two of these processes. (a) 7 and 13 seconds (b) 17 and 14 seconds (c) 5 and 17 seconds (d) 9 and 15 seconds ..read more

I had to alter your suggested solution as find ~ in your suggestion find ~ -type f -not -readable doesnt work and throws an error. The correction I posted, perfectly found the files with read errors, so it works great for me. It was such a minor change to your solution that I did not bother to mention it ..read more

Keep in mind that this command (find . -type f -not -readable) really finds files that you cannot read (i.e., you lack read permission), not just files with read errors (i.e., disk errors).
