CHECKDIGITS(1) User Contributed Perl Documentation CHECKDIGITS(1)NAME
checkdigits - check or generate check digits
VERSION
This document describes checkdigits version 0.0.1
SYNOPSIS
checkdigits [Options] command [[number] ...]
options:
-algorithm alg - use this algorithm
commands:
check - check validity of number containing checkdigit
checkdigit - return checkdigit belonging to number
complete - return number completed with checkdigit
list_algorithms - list all known algorithms
describe - describe the given algorithms
DESCRIPTION
This is a command line program that may be used to compute any
checkdigit known by the perl module Algorithm::CheckDigits.
OPTIONS AND COMMANDS
Options
-algorithm alg
Compute checkdigits according to algorithm alg. Instead of providing
the algorithm with this option, you may choose to rename the program to
the name of the algorithm or to "checkdigits-" followed by the name of
the algorithm.
You must provide the algorithm with any of these means or the program
will not compute any checkdigit.
Commands
check
checkdigit
complete
When called with this command, the program will take the number compute
the appropriate checkdigits and return the complete number with
checkdigits.
describe
Called with this command, the program will list the algorithm handles
given on the command line with a short description or the word
"unknown" for any unknown algorithm. See command list_algorithms for a
list of known algorithms.
list_algorithms
Called with this command, the program will list all known algorithms
together with a short description and then exit.
DIAGNOSTICSCONFIGURATION AND ENVIRONMENT
At the moment the program doesn't recognise any environment variables.
The algorithm to use may be predefined by renaming the program to the
name of the algorithm or to "checkdigits-" followed by the name of the
algorithm.
