Yeah, exactly like that. At minimum, they need to be able to search the first two digits and at max the whole thing. Searching only the first digit would be the equivalent of not using -v.

All software versions start with two digits, followed by a .
The place after .contains a single digit of 0-9
After that the next character is either R or S
After R or S it seems the next digit could be 0-9 or double digit like 11 followed by a . then a single digit 0-9

I don't want to limit any of the engineers from being able to search a full version, because I don't know how specific of a version someone might want to search for. I do know at minimum, they have to use -vfollowed by two digits.

If whatever they search for doesn't exist, a simple "No match found" message will suffice.

Ex:

Code:

cver -c -v 14
No match found

Whatever they do search that exists shows everything up to what they searched and includes anything that may be after it.

Ex:

Code:

cver -c -v 12.3
[12.3R6.6] device1-r0.cpe.domain.net
[12.3R6.6] device2-r0.cpe.domain.net
[12.3R7.7] device3-r1.cpe.domain.net
...

I hope that answers your questions.

NAME

       CheckDigits::M07_001 - compute check digits modulo 7 method 1

SYNOPSIS

	 use Algorithm::CheckDigits;

	 $m001 = CheckDigits('m001');

	 if ($m001->is_valid('1234567892')) {
	       # do something
	 }

	 $cn = $m001->complete('123456789');	# $cn = '1234567892'

	 $cd = $m001->checkdigit('1234567892'); # $cd = '2'

	 $bn = $m001->basenumber('1234567892'); # $bn = '123456789'

DESCRIPTION

   ALGORITHM
       1.  All digits are added.

       2.  All digits at even positions are added.

       3.  The sum of step 1 and 2 is taken modulo 7.

       4.  This is the check digit.

   METHODS
       is_valid($number)
	   Returns true only if $number consists solely of numbers and the last digit is a valid check digit according to the algorithm given
	   above.

	   Returns false otherwise,

       complete($number)
	   The check digit for $number is computed and concatenated to the end of $number.

	   Returns the complete number with check digit or undef if $number does not consist solely of digits.

       basenumber($number)
	   Returns the basenumber of $number if $number has a valid check digit.

	   Return undef otherwise.

       checkdigit($number)
	   Returns the check digit belonging to $number or undef if $number does not consist solely of digits.

   EXPORT
       None by default.
