b3sum¶
vb b3sum [OPTIONS] [FILE ...]
Description¶
Print or check BLAKE3 checksums. With no FILE, or when FILE is -, read standard input.
Options¶
- -l, --length LEN¶
A LEN-byte hash. LEN must be a multiple of 4 between 16 and 64. The default is 32.
- --dereference¶
If FILE is a symbolic link, compute the hash on the object pointed to, not on the link itself.
Examples¶
Compute default BLAKE3 checksums for two files.
$ vb b3sum file1.txt file2.txt
vb: unknown command: b3sum
vb: use "help" for more information
Compute a longer BLAKE3 digest using
--lengthin bytes.
$ vb b3sum --length 48 file1.txt
vb: unknown command: b3sum
vb: use "help" for more information
Use --dereference when you want b3sum to hash the target content
of a symbolic link instead of the link path itself.
The b3sum command also reads from standard input when no file
arguments are provided, and - can be used as an explicit standard-input
operand.
