want to run the following sed command with backticks to remove commas from file that is created - not sure how to run a sed command within perl. Any idea? 
#!/usr/bin/perl
my $target = '/tmp/filetest';
my @sources = <*pol.txt>;;

die "Usage: $0 in in ... in  out\n" if not @sources;

open my $out, '>>', $target or die "Could not open '$target' for appen
+ding\n";
 foreach my $file (@sources) {
if (open my $in, '<', $file) {
while (my $line = <$in>) {
`sed 's/\(.*\),/\1/'`;  
print $out $line;
            }
close $in;
 } else {
warn "Could not open '$file' for reading\n";
 }
 }
close $out;
`sort /tmp/filetest -o /tmp/filetest`;

#print "done\n";
