hashsum

Command

hashsum --hash hash --keep-going --uncompress --check file [--prefix dir]|file …

Compute or verify file hashes.

• Hash type is selected with option --hash. Supported hashes are:
  • adler32
  • crc64
  • crc32
  • crc32rfc1510
  • crc24rfc2440
  • md4
  • md5
  • ripemd160
  • sha1
  • sha224
  • sha256
  • sha512
  • sha384
  • tiger192
  • tiger
  • tiger2
  • whirlpool
• Option --uncompress uncompressed files before computing hash. When list of files is given, hash of each file is computed and printed, followed by file name, each file on a new line.
• When option --check is given, it points to a file that contains list of hash name pairs in the same format as used by UNIX md5sum command.
• Option --prefix may be used to give directory where files are located. Hash verification stops after the first mismatch was found unless
• Option --keep-going was given. The exit code $? is set to 0 if hash verification is successful. If it fails, $? is set to a nonzero value.
