Re: Forcing array context on a file handle

Did you check perldoc? This is a FAQ

perldoc -q "How do I count the number of lines in a file"

Hi, ronmrdechai

$lines = grep {$_} <$file>;

[QM]

That works for files in the default case, because every line will have a newline or somesuch, and will not be an empty string. For counting, map would be more appropriate than grep. But tobyink showed the idiom above:

my $lines =()= <$file>;
