SYNOPSIS

12         checkdigits [Options] command [[number] ...]
13
14         options:
15
16          -algorithm alg - use this algorithm
17
18         commands:
19
20          check           - check validity of number containing checkdigit
21          checkdigit      - return checkdigit belonging to number
22          complete        - return number completed with checkdigit
23          list_algorithms - list all known algorithms
24          describe        - describe the given algorithms
25

DESCRIPTION

27       This is a command line program that may be used to compute any
28       checkdigit known by the perl module Algorithm::CheckDigits.
29

OPTIONS AND COMMANDS

31   Options
32       -algorithm alg
33
34       Compute checkdigits according to algorithm alg. Instead of providing
35       the algorithm with this option, you may choose to rename the program to
36       the name of the algorithm or to "checkdigits-" followed by the name of
37       the algorithm.
38
39       You must provide the algorithm with any of these means or the program
40       will not compute any checkdigit.
41
42   Commands
43       check
44
45       checkdigit
46
47       complete
48
49       When called with this command, the program will take the number compute
50       the appropriate checkdigits and return the complete number with
51       checkdigits.
52
53       describe
54
55       Called with this command, the program will list the algorithm handles
56       given on the command line with a short description or the word
57       "unknown" for any unknown algorithm. See command list_algorithms for a
58       list of known algorithms.
59
60       list_algorithms
61
62       Called with this command, the program will list all known algorithms
63       together with a short description and then exit.
64

DIAGNOSTICS

CONFIGURATION AND ENVIRONMENT
67       At the moment the program doesn't recognise any environment variables.
68
69       The algorithm to use may be predefined by renaming the program to the
70       name of the algorithm or to "checkdigits-" followed by the name of the
71       algorithm.
