SHA1SUM(1) SHA1SUM(1) sha1sum - compute and check SHA1 message digest sha1sum []... []... ,,SHA1" (160-) . , -, . -b, --binary -c, --check read checksums from the FILEs and check them --tag -t, --text () -z, --zero , : --ignore-missing --quiet --status , --strict - -w, --warn --help --version The sums are computed as described in FIPS-180-1. 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. There is no difference between binary mode and text mode on GNU systems. Do not use the SHA-1 algorithm for security related purposes. Instead, use an SHA-2 algorithm, implemented in the programs sha224sum(1), sha256sum(1), sha384sum(1), sha512sum(1), or the BLAKE2 algorithm, implemented in b2sum(1) , . coreutils: Copyright (C) 2024 Free Software Foundation, Inc. 3+: 3 . : . , . cksum(1) ,,info '(coreutils) sha1sum invocation'" ; 3 . . , - TODO <>. coreutils 9.5 2024 SHA1SUM(1)
