B2SUM(1)                         User Commands                        B2SUM(1)
NAME
       b2sum - compute and check BLAKE2 message digest
SYNOPSIS
       b2sum [OPTION]... [FILE]...
DESCRIPTION
       Print or check BLAKE2 (512-bit) checksums.
       With no FILE, or when FILE is -, read standard input.
       -b, --binary
              read in binary mode
       -c, --check
              read BLAKE2 sums from the FILEs and check them
       -l, --length
              digest  length  in  bits;  must  not  exceed the maximum for the
              blake2 algorithm and must be a multiple of 8
       --tag  create a BSD-style checksum
       -t, --text
              read in text mode (default)
       -z, --zero
              end each output line with NUL, not  newline,  and  disable  file
              name escaping
   The following five options are useful only when verifying checksums:
       --ignore-missing
              don't fail or report status for missing files
       --quiet
              don't print OK for each successfully verified file
       --status
              don't output anything, status code shows success
       --strict
              exit non-zero for improperly formatted checksum lines
       -w, --warn
              warn about improperly formatted checksum lines
       --help display this help and exit
       --version
              output version information and exit
       The  sums  are  computed  as described in RFC 7693.  When checking, the
       input should be a former output of this program.  The default  mode  is
       to  print  a  line with checksum, a space, a character indicating input
       mode ('*' for binary, ' ' for text or where binary  is  insignificant),
       and name for each FILE.
       Note:  There  is no difference between binary mode and text mode on GNU
       systems.
