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

nothing i know beats this for speed. there's a node on this technique somewhere around here...

my $file = 'sample.txt';
{
  local *FH;
  -f FH and sysread FH, my $file, -s FH;
}

Don't see how this works. This must just be a fragment. Seems like you need at least this much: `my $file = 'sample.txt'; my $buf; { local *FH; open FH, "$file" or die $!; -f FH and sysread FH, $buf, -s FH; }` [download] results are in `$buf` after the read... Unless you meant to write to `sample.txt` in the first place, and `FH` was just presumed open to some readable file... thanks, -Cadphile...	[reply] [d/l]
