6.4 b2sum
: Print or check BLAKE2 digests
b2sum
computes a 512-bit checksum for each specified
file
. The same usage and options as the md5sum
command are supported. See md5sum invocation.
In addition b2sum
supports the following options.
- ‘
-l
’
‘--length
’ Change (shorten) the default digest length. This is specified in bits and thus must be a multiple of 8. This option is ignored when
--check
is specified, as the length is automatically determined when checking.
