Hello monks...
I have kind of a question...I have this code that pushes lines to an array if a certain condition is true:
my (@search);
my $query = "perl";
open(FILE, "myfile.txt");
flock(FILE, 1);
my @lines = <FILE>;
close(FILE);
foreach my $lines(@lines){
chomp($lines);
push(@search, $lines) if grep { /$query/ } $lines;
}
This checks each line to see if it has the word perl in it...if it has it pushes the whole line to the
@search array.
My problem is that sometimes the text doesnt have the word..so I need to know if
@search has any content...
How can I do this?
I already tried
if(@search){
print "Hey...I found something\n"
}
But it doesnt seem to work...
Any help is gladly accepted...
Thanks
