Using filename to determine a prefix that needs to be added to string column on file?
Possible filenames:

CDD_Whatever.txt
DDD_Whatever.txt

If the file prefix = CDD, I'd like to prefix every person ID (second column in my examples below) on the file with "c-"

If the file prefix = DDD, I'd like to prefix ever person ID with "d-"

Input:
Quote:
01|5284338|Person 1|SAT Mail|75
Desired Output:
Quote:
02|c-5284338|Person 1|SAT Mail|75
Any help would be appreciated

Mail::SPF::Mech::MX(3)					User Contributed Perl Documentation				    Mail::SPF::Mech::MX(3)

NAME

       Mail::SPF::Mech::MX - SPF record "mx" mechanism class

DESCRIPTION

       An object of class Mail::SPF::Mech::MX represents an SPF record mechanism of type "mx".

   Constructors
       The following constructors are provided:

       new(%options): returns Mail::SPF::Mech::MX
	   Creates a new SPF record "mx" mechanism object.

	   %options is a list of key/value pairs representing any of the following options:

	   qualifier
	   domain_spec
	   ipv4_prefix_length
	   ipv6_prefix_length
	       See "new" in Mail::SPF::Mech.

       new_from_string($text, %options): returns Mail::SPF::Mech::MX; throws Mail::SPF::ENothingToParse, Mail::SPF::EInvalidMech
	   Creates a new SPF record "mx" mechanism object by parsing the string and any options given.

   Class methods
       The following class methods are provided:

       default_qualifier
       default_ipv4_prefix_length
       default_ipv6_prefix_length
       qualifier_pattern
	   See "Class methods" in Mail::SPF::Mech.

       name: returns string
	   Returns 'mx'.

       name_pattern: returns Regexp
	   Returns a regular expression that matches a mechanism name of 'mx'.

   Instance methods
       The following instance methods are provided:

       text
       qualifier
       params
       stringify
       domain
       match_in_domain
	   See "Instance methods" in Mail::SPF::Mech.

       domain_spec: returns Mail::SPF::MacroString
	   Returns the "domain-spec" parameter of the mechanism.

       ipv4_prefix_length: returns integer
	   Returns the IPv4 network prefix length of the mechanism.

       ipv6_prefix_length: returns integer
	   Returns the IPv6 network prefix length of the mechanism.

       match($server, $request): returns boolean
	   Checks whether any MX hosts of the mechanism's target domain name (that is, any of the host addresses of its DNS "MX" records) matches
	   the given request's IP address (see "ip_address" in Mail::SPF::Request), and returns true if it does, or false otherwise.  The
	   mechanism's IP network prefix lengths are respected when matching address records against the request's IP address.	See RFC 4408, 5
	   and 5.4, for the exact algorithm used.
