Re: Opening external files with arguements

Sorry, I can't understand what you mean. Care to expand?

FWIW:

#!/usr/bin/perl

use strict;
use warnings;

my $file=shift or die "Usage: $0 <file>";
open my $fh, $file or die $!;
print scalar <$fh>;

__END__

Can be used e.g. like thus:

$ ./foo.pl 'ls|'
449133.pl
[download]

(But then this is precisely the reason why I prefer the three args form of open() - there are situations in which you may want to do exactly the above, though!)

Three arguements form? Would you mind giving me a (simple) example?	[reply]

Three arguements form? Would you mind giving me a (simple) example? I must say i'm tempted to say: no! For I'm not here (and nobody is) to replace the best tool to answer this kind of questions, that is Perl's excellent documentation. However... `open my $fh, '\|-', "whatever" or die $!; # or open my $fh, '\|-', "whatever", @more_args or die $!;` [download]	[reply] [d/l]
