Building a string to contain a "/"

Hello

I am trying to build a string that contains the following text "dir
c:\ /S" so I can get a complete directory of all the files on drive C
and put them into an array with the following line of code -
@dir_list = 'dir c:\ /S`;

Right now I have the following working:

However, it is now working:

@dir_list = 'dir c: /S`; which gives me all the files in the
directory that is being pointed to at the moment for C: and all the
subdirectories.

Andrew

You have to escape it with another backslash. 'C:\\ /S'

Keep up with my goings on at http://theillien.blogspot.com

The backslash is the escape char. If you need a literal \ in the
command, then you'll need to escape it by doubling it up i.e.,
my @dir_list = `dir c:\\ /S`;

Rather than using the backticks to execute the dir command which you
then need to parse, a better approach would be to use the File::Find
module (or one of its cousins).
http://search.cpan.org/search?query=file%3A%3Afind&mode=all

use strict;
use warnings;
use File::Find;

my @file_list;
my $dir = 'c:/';

find(\&file_listing, $dir);

sub file_listing {
return if -d; # skip over directory entries

# add file name onto the array
push @file_list, $_;

# or add filename with path info onto array
#push @file_list, $File::Find::name;
}

print scalar @file_list " files in/under $dir;

Use single quotes:

my $command = 'dir c:\ /s';

my @dir_list = `$command`;
