IPC using Perl

[SaltyDuke]

Hello!!

i have a bit of a strange noodle-scratcher at the moment.

i have a program that "writes" data out to another program which in turn parses that data and writes it to a database.

i would like to write a Perl program to do this. Is this a good idea or should i go for C instead? (i'm very lazy though!!)

if it is possible for Perl to "listen in" for info off another process (via stdin or stderr i guess), how do i do it? it can't just be:

$var = <STDIN>;

can it???

Thanx in advance for any help,
TheSaltyDuke

It sounds like you just want a pipe. The easiest way is to pipe the output of the program to your Perl script from the command line when you call it:

%perl script | prog

An alternative if the parsing program is known is to open a file handle inside your script:

#!usr/bin/perl -w

open(PARSER, "parser |") or die $!;

while (<PARSER>)
{
    print $_, &quot;\n&quot;; # Just print it to test
}

close(PARSER);

Yes, both solutions work in Windows as well.
