Print CRC and size for each file

NAME

cksum - Print CRC and size for each file

SYNOPSIS

cksum [-a|--algorithm] [--untagged] [--tag] [-l|--length] [--raw] [--strict] [-c|--check] [--base64] [-w|--warn] [--status] [--quiet] [--ignore-missing] [-z|--zero] [-h|--help] [-V|--version] [file]

DESCRIPTION

Print CRC and size for each file

OPTIONS

-a, --algorithm=ALGORITHM

select the digest type to use. See DIGEST below

[possible values: sysv, bsd, crc, crc32b, md5, sha1, sha3, sha224, sha256, sha384, sha512, blake2b, blake3, sm3, shake128, shake256]

--untagged

create a reversed style checksum, without digest type

--tag

create a BSD style checksum, undo --untagged (default)

-l, --length

digest length in bits; must not exceed the max for the blake2 algorithm and must be a multiple of 8

--raw

emit a raw binary digest, not hexadecimal

--strict

exit non-zero for improperly formatted checksum lines

-c, --check

read hashsums from the FILEs and check them

--base64

emit a base64 digest, not hexadecimal

-w, --warn

warn about improperly formatted checksum lines

--status

don't output anything, status code shows success

--quiet

don't print OK for each successfully verified file

--ignore-missing

don't fail or report status for missing files

-z, --zero

end each output line with NUL, not newline,
and disable file name escaping

-h, --help

Print help

-V, --version

Print version

EXTRA

DIGEST determines the digest algorithm and default output format:

- sysv: (equivalent to sum -s) - bsd: (equivalent to sum -r) - crc: (equivalent to cksum) - crc32b: (only available through cksum) - md5: (equivalent to md5sum) - sha1: (equivalent to sha1sum) - sha224: (equivalent to sha224sum) - sha256: (equivalent to sha256sum) - sha384: (equivalent to sha384sum) - sha512: (equivalent to sha512sum) - blake2b: (equivalent to b2sum) - sm3: (only available through cksum)

VERSION

v0.0.30

History

--base64 since Debian 13 (Trixie); --raw since Debian 13 (Trixie); -V since Debian 13 (Trixie); -h since Debian 13 (Trixie).

--debug until Debian 12 (Bookworm).
