how to seperate the run time argument with | character

Hi,

I have a perl script, where I am passing more than 3 arguments, but I
want to seperate them with |(pipe)or any other special charcater
instead of blank space, cause the argument itself I have the space
like " sixty three".
For example c:\perl>perl sample.pl sixty three|fouty four| twenty two
in windows.

now I am passing the argument like

c:\perl>perl sample.pl two three four, when you do not have the space
in the argument itself then it is fine otherwise it is taking
everything as an argument.

Could anyone please help me on this issue?


Thanks!

Bala!!!

The correct way to do this is to quote the arguments that contain
characters the shell cares about (space, |, &, [, $, etc):

perl sample.pl 'this is one argument' two three

Don't need the pipe symbol. Use single quote for each argument.

> cat t2.pl
use strict;
use Data::Dumper;
print Dumper \@ARGV;

> perl t2.pl 'aa bb' 'cc dd'
$VAR1 = [
'aa bb',
'cc dd'
];

c:\perl>perl sample.pl "sixty three" "fouty four" " twenty two"

As you can see it's passed to the script corectly:

perl -MData::Dumper -e "print Dumper(\@ARGV)" "sixty three" "fouty
four" " twenty two"

If you want to be able to use singlequotes, want parameter globing
(handling of a*.txt) and a few other goodies in Windows similar to
the way you'd do that in Unix you may try http://Jenda.Krynicky.cz/#G
