Calculate BLAKE2 cryptographic checksums. More information: https://www.gnu.org/software/coreutils/b2sum.
- Calculate the BLAKE2 checksum for one or more files:
b2sum {{path/to/file1 path/to/file2 ...}}
- Calculate and save the list of BLAKE2 checksums to a file:
b2sum {{path/to/file1 path/to/file2 ...}} > {{path/to/file.b2}}
- Calculate a BLAKE2 checksum from
stdin
:
{{command}} | b2sum
- Read a file of BLAKE2 sums and filenames and verify all files have matching checksums:
b2sum --check {{path/to/file.b2}}
- Only show a message for missing files or when verification fails:
b2sum --check --quiet {{path/to/file.b2}}
- Only show a message when verification fails, ignoring missing files:
b2sum --ignore-missing --check --quiet {{path/to/file.b2}}
