Help Please!!! External APP passing value to Perl

Perl

2005-07-24, 8:29 pm

Hello Listners,

I am totally novice in perland I need help with that script.
what can be the syntex of assigning a variable (my $path) in perl which is
taking value (for example c:\documents\script.txt) from an expternal APP.
The script will actually parse the my$path value (C:\documents\script.txt)
to (script.txt) and then will send parse value of my$path to STDOUT.
I am not sure how should I declare the value of my$path.

The script looks like this

\#!/usr/bin/perl
use strict;
use File::Basename;

my $path = Variable from external app
my $base = basename($path);
my $dir = dirname($path);
print STDOUT $base;

I will really appreciate any help/comment on it.

thanks

How is your program getting passed this value? On the command-line? If
so, then you would access the value from the @ARGV array. $ARGV[0] holds
the first argument, $ARGV[1] the second, and so on.

my $path = $ARGV[0];

If it's being sent to your program via an input stream (the other program
is writing, and your Perl program needs to read), you'd get the value from
<STDIN>.

chomp(my $path = <STDIN> );
