Re: Re: Reading Log file from bottom up and take first 100 lines and send email...

@x = @x[($#x-100>0?$#x-100:0)..$#x];

I find @x = @x[0..99] if @x > 100; to be more readable. YMMV.

Well, the question was about taking the last 100 lines. You can use `splice` for that: `splice @x => 0, -100;` [download] will keep the last 100 lines in `@x`. If you just want to keep the first 100, use `splice @x => 100;` [download] Both will work without warnings if `@x` contains less than 100 elements. Abigail	[reply] [d/l] [select]

Good point. But it needs to be `@x = reverse(@x[reverse -99..-1]) if @x > 100;` [download] ? updated sorry, I wrongfully read a question, I thought about last 100 lines. My wrong. Courage, the Cowardly Dog	[reply] [d/l]
