You should escape the "$2" with backslashes otherwise it gets interpolated by perl.
A better way? Umm, that depends on the point of view. To me, a better way is a perl only way to minimize dependency on external programs and platform independent as well. So instead of using external programs, I would do it in perl.
use IO::File;
...
my $good = getvalue($file, $vals[0]);
...
sub getvalue
{
my ($file, $val) = @_;
my $val;
my $f = new IO::File $file, "r" or die "Can not open file";
while (my $line = <$f>) {
if ($line =~ /$val/) {
return (split /,/, $line)[1]; # return 2nd field
}
}
return undef;
}
