B2SUM(1) B2SUM(1) b2sum - compute and check BLAKE2 message digest b2sum []... []... Print or check BLAKE2b (512-bit) checksums. , -, . . -b, --binary -c, --check read checksums from the FILEs and check them -l, --length=BITS digest length in bits; must not exceed the max for the blake2 algorithm and must be a multiple of 8 --tag -t, --text () -z, --zero , : --ignore-missing --quiet --status , --strict - -w, --warn --help --version 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. : . . coreutils: Copyright (C) 2023 Free Software Foundation, Inc. 3+: 3 . : . , . cksum(1) ,,info '(coreutils) b2sum invocation'" ; 3 . . , - TODO <>. coreutils 9.4 2024 B2SUM(1)
