hashsum 1.4.1

用法

usage: hashsum [-h] [-a] [--tag] [-b | -t] [-c | -l] [--quiet]
               [--status] [--strict] [-w] [-m] [--version]
               [FILE [FILE ...]]

Compute and check message digest with different hash algorithms.
The sums are computed as described in [1].
When checking, the input should be a former output of this program.
The default mode is to print a line with checksum, a character
indicating input mode ('*' for binary, space for text), and name
for each FILE.

positional arguments:
  FILE                  name of file to process. If not specified,
                        or set to -, data are read form the
                        standard input

optional arguments:
  -h, --help            show this help message and exit
  -a , --algorithm      specify the hashing algorithm
                        (default: 'md5')
  --tag                 create a BSD-style checksum
  -b, --binary          read input data in binary mode
  -t, --text            read input data in text mode (default)
  -c, --check           read checksum(s) form FILE and check them
  -l, --list-algorithms
                        list available hashing algorithms
  -m, --multi-thread    perform I/O and hash computation in separate threads
                        (default=False). Can speed-up computation on large
                        files while it is not recommended for small files.
  --version             show program's version number and exit

check:
  Options that are useful only when verifying checksums

  --quiet               don't print OK for each successfully
                        verified file
  --status              don't output anything, status code shows
                        success
  --strict              exit non-zero for improperly formatted
                        checksum lines
  -w, --warn            warn about improperly formatted checksum
                        lines
