listing with variables

I was hoping I could use a command like

$onefile = 'ls -l $names[$loop]';

where $names[$loop] holds the name of a file

It does not work though. Obviously what I am trying to do is get a listing for a single file.

Anyone tell me why the above line does not work or an alternative method.

Thanks

------------------

my @files = ('file1', 'file2', 'etc');

foreach my $file (@files) {
my $onefile = `ls -l $file`;
}

(i'm assuming your problems was interpolation of the array elemenent and not single quotes vs. tick ( ' vs. ` )
