See my edit, apparently shasum's -c can read from stdin so you could simplify your scriptlet even further :)

Indeed,

      echo '98ea6e4f216f2fb4b69fff9b3a44842c38686ca685f3f55dc48c5d3fb1107be4  some_file' | sha256sum -c
also works (with and without passing `-n` to echo, because the `-c` option ensures the file is checked without even noticing any new line). Thanks :)
