MD5SUM(1) MD5SUM(1) md5sum - compute and check MD5 message digest md5sum []... []... Print or check MD5 (128-bit) checksums. Legacy interface to the cksum utility. , -, . -b, --binary -c, --check --tag -t, --text () -z, --zero , : --ignore-missing --quiet --status , --strict - -w, --warn --help --version The sums are computed as described in RFC 1321. 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. . Do not use the MD5 algorithm for security related purposes. Instead, use an SHA-2, SHA-3, or BLAKE2 algorithm, implemented in the cksum(1) program. , . : bug-coreutils@gnu.org coreutils : : Copyright (C) 2026 Free Software Foundation, Inc. 3+: 3 . : . , . cksum(1) ,,info '(coreutils) md5sum invocation'" ; 3 . . , - TODO <>. coreutils 9.11 2026 MD5SUM(1)
