for my $line (`head -30 $fullfile`) Consider that not every OS has the `head` command, this suggested route of using backticks to run a system command isn't portable.	[reply] [d/l] [select]

I don't see a logical argument for suggesting backticks to a system command, when safer, portable options exist.	[reply]
