Re: Re: Skip 21 Lines

Something I always use for the xth line of a file....
(undef,undef,undef,undef,$line) = <FILE>;
[download]

At the expense of reading the entire file and tossing all but one of the lines. Ouch!

Isn't it more maintainable to write that as: `$line = (<FILE>)[4];` [download] ?	[reply] [d/l]

I presume you're joking. That's the same problem. Read the whole file, keep the fifth element. Ugh. -- Randal L. Schwartz, Perl hacker	[reply]

Yes, that was a joke. But if you are going to be inefficient, at least be idiomatically inefficient. I didn't like having to count through undefs to figure out which line you were grabbing...	[reply]
