Question

Im trying to surround all values in my hash with single quotes. here is my code.

    foreach(values(%properties_hash))
    {
            print "'".$_."'\n";
    }

Right now I’m printing. How would I actually augment the value. Also this prints

'logs
'format/systemout-2010-format.txt
'analyze

It is only
printing the first ‘. Why would that be?

Thanks!

Your code is working.

my %h = (
        'a' => 1,
        'b' => 2,
        'c' => 3,
        'd' => 4,
);

foreach(values(%h)) {
        print "'".$_."'\n";
}

prints

'3'
'1'
'2'
'4'

Your strings are probably ended with “\r”, so the ending “‘” is printed over 1 st “‘” and therefore don’t see the last apostrophe. try:

foreach(values(%h)) {
        s/[\r\n]//g;
        print "'".$_."'\n";
}
