+# b3sum
+
+> Command line utility for calculating BLAKE3 hashes.
+> It is similar to Coreutils tools like b2sum or md5sum.
+> More information: <https://github.com/BLAKE3-team/BLAKE3/tree/master/b3sum>.
+
+- Calculate the BLAKE3 checksum for a file:
+
+`b3sum {{path/to/file}}`
+
+- Calculate BLAKE3 checksums for multiple files:
+
+`b3sum {{path/to/file1}} {{path/to/file2}}`
+
+- Calculate the BLAKE3 checksum from `stdin`:
+
+`{{some_command}} | b3sum`
+
+- Create a file of BLAKE3 checksums:
+
+`b3sum {{path/to/file}} > {{path/to/file.b3}}`
+
+- Read and verify a file of BLAKE3 checksums:
+
+`b3sum --check {{path/to/file.b3}}`
