next unless - doesnt work?

So i have:

next unless ( grep( /$name/, @names ));
print "$name isnt in the array so continue";
[download]

it prints nothing, even though the name is there. however, this works:

if ( grep( /$name/, @names )) {
   print "name is in the array";
}
#but this doesnt suit my needs.
[download]

thx for help :)

Show us the complete loop. "If LABEL is omitted, the command refers to the innermost enclosing loop" (next) update: better to do `grep {$name eq $_} @names`	[reply] [d/l]

ah i solved the problem using ne instead of eq :) and for some reason != didnt do the job but ne did.. strange?	[reply]

Not strange ;) != and == are for numeric context comparisons where eq/ne are for evaluating strings. Your original post didn't show any code relating to evaluations, so I, nor anyone else have any idea how this was part of your problem in the first place.	[reply]

and for some reason != didnt do the job but ne did.. strange? Not at all. One is for numbers, the other for strings. You would've gotten a warning if you had `use warnings` on.	[reply] [d/l]

Not at all strange: ne is used for alphas; != for numbers.	[reply]
