Re: How do I read an entire file into a variable?

in reply to How do I read an entire file into a variable?

Be careful with things like join("",<HANDLE>); If you have thousands of consecutive newlines, perl has to first create the array and then join it. That can get expensive. Do benchmarking. But I like something simillar to the following:

my $buf=$content='';
$content.=$buf while read(HANDLE,$buf,8192);

8192 is arbitrary so optimize with glee.

The simple thought of reading a whole file (read: HD => BIG) into a variable (read: RAM => small) is pretty expensive by itself.. of course i get your point of it being even more expensive when you also need to use processing time to join it after clogging your ram.. (btw, my first post ;-} ) (sorry if i sounded harsh..)	[reply]
