Hi,
Is there a way to evaluate an equation contained in a string within an AWK script?
For example:
A = "(5*2)-1" (this equation is read from a file and varies line by line)
In this example, I can't see any way to get an answer of 9 unless I do:
cmd = "awk 'BEGIN{print "A"}'"

Net::Server::MultiType(3) User Contributed Perl Documentation Net::Server::MultiType(3)NAME
Net::Server::MultiType - Net::Server personality
SYNOPSIS
use Net::Server::MultiType;
@ISA = qw(Net::Server::MultiType);
sub process_request {
#...code...
}
my @types = qw(PreFork Fork Single);
Net::Server::MultiType->run(server_type=>@types);
DESCRIPTION
Please read the pod on Net::Server first. This module is a personality, or extension, or sub class, of the Net::Server module.
This personality is intended to allow for easy use of multiple Net::Server personalities. Given a list of server types,
Net::Server::MultiType will require one at a time until it finds one that is installed on the system. It then adds that package to its
@ISA, thus inheriting the methods of that personality.
ARGUMENTS
In addition to the command line arguments of the Net::Server base class, Net::Server::MultiType contains one other configurable parameter.
Key Value Default
server_type 'server_type' 'Single'
server_type
May be called many times to build up an array or possible server_types. At execution, Net::Server::MultiType will find the first
available one and then inherit the methods of that personality
