# uu-cksum(1)

Print CRC and size for each file

## NAME

cksum - Print CRC and size for each file

## SYNOPSIS

**cksum** \[OPTIONS\] \[FILE\]...

## 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

  - •

    sha2

  - •

    sha3

  - •

    blake2b

  - •

    sm3

  - •

    sha224

  - •

    sha256

  - •

    sha384

  - •

    sha512

  - •

    blake3

  - •

    shake128

  - •

    shake256

- **--untagged**

  create a reversed style checksum, without digest type

- **--tag**

  create a BSD style checksum (default)

- **-l**, **--length**

  digest length in bits; must not exceed the max size and must be a multiple of 8 for blake2b; must be 224, 256, 384, or 512 for sha2 or sha3

- **--raw**

  emit a raw binary digest, not hexadecimal

- **-c**, **--check**

  read checksums from the FILEs and check them

- **-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

- **--strict**

  exit non-zero for improperly formatted checksum lines

- **--base64**

  emit base64-encoded digests, not hexadecimal

- **-z**, **--zero**

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

- **--debug**

  print CPU hardware capability detection info used by cksum

- **-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\
   \- sha2: equivalent to sha{224,256,384,512}sum\
   \- sha3: only available through cksum\
   \- blake2b: equivalent to b2sum\
   \- sm3: only available through cksum
