Question

This is what I’m trying to do:

$variable = `grep -i "Text: Added to directory" '$FOO/result.txt' | awk '{print $6}' | tr -d "'"`
print $variable;

Output:

Text: Added to directory /path/to/directory/
Use of uninitialized value $6 in concatenation (.) or string

How can I fetch just “/path/to/directory” instead of “Text: Added to directory /path/to/directory/”?

Of course Perl can do what grep, awk and tr can do.

open my $fh, "<", "$FOO/result.txt" or die "can't open file: $!\n";
while (<$fh>) {
    next unless /pattern/i;
    (my $six = (split)[5]) =~ tr/'//d;
    print $six, "\n";
}
close $fh;
