Hi,
I thought this would be simple...
I want to supply the name of a file on the command line when executing a
script. Unfortunately, I'm getting an error that says that @ARGV is
uninitialized.
How do you initialize @ARGV? How do you specify command line arguments?
I'm using Windows XP, activestate Perl 5.8.3.
>From the Command Prompt:
C:\Perl\my_scripts>argv_test.pl cookies.txt
Use of uninitialized value in print at C:\Perl\my_scripts\argv_test2.pl
line 4.
Use of uninitialized value in open at C:\Perl\my_scripts\argv_test2.pl
line 5.
readline() on closed filehandle INFILE at
C:\Perl\my_scripts\argv_test2.pl line
6.
Quoting cookies.txt doesn't change the error message.
When I push a value onto @ARGV, the script works fine.
Any insight will be very appreciated.
Larry.
argv_test.pl
use warnings;
#push @ARGV, "cookie.txt"; # when uncommented script works fine.
my $name = $ARGV[0];
print $name;
open (INFILE, $name);
while (<INFILE>) {
print $_;
}
close INFILE;
