How would I get the various elements out of a string of known format.
A previous post about a similar topic approaches a solution but I need
help with the regular expression to pass to the m function.
Here's an example of a string:
net user cknotts somepassword /add /active:yes /expires:never

use warnings;
use strict;
my $var = 'world';

Yes, I've read that. I can't seem to make it work though. Perhaps you

Hello, my Perl skills are very weak. I have a chunk of code that
works great as long as I hard-code everything. When I try to use

Hello,
my $image = Image::Magick-new;
# trouble
open(IMAGE, 'images/products/unprocessed/$sku_unprocessed.jpg');

You need to use double quotes if you want it to use the variable.
or if you reall wanted single quotes you could have

Actually, since the others are numbers you could replace the last two \S+
with \d+

I think that needs to be:
my ($target,$count,$num) = split /\s+/, $word;
to handle multiple spaces between the values.
No. As the split() documentation states, split(' ') is magical.

So if you wanted to split on just one space, would split / /,$variable be
treated as magical as well?

No. As the split() documentation ALSO states, only split(' ') and
split( ) are treated magically. split(/ /) splits on a single
space; the others split as if

That always confused me, by default split splits by /\s+/ so why confuse us
more by making and ' ' magical.
No, the default is NOT /\s+/, the following are all equivalent:
@words = split;
@words = split ' ';
@words = split ' ', $_;
