Calculate BLAKE2 cryptographic checksums. More information: <https://www.gnu.org/software/coreutils/b2sum>.
-
Calculate the BLAKE2 checksum for a file:
b2sum path/to/file
-
Calculate BLAKE2 checksums for multiple files:
b2sum path/to/file1 path/to/file2
-
Calculate the BLAKE2 checksum from stdin:
some_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 for files for which verification fails, ignoring missing files:
b2sum --ignore-missing --check --quiet path/to/file.b2
