New Its not large - its small
and the only api I see is "read n bytes" or "read n bytes starting at m". No line oriented interface that I can see.

Which is annoying as hell, so I'll just read it all. Anyhow, if the file exceeds 20k I will be amazed.



That was lovely cheese.

New Perl is line oriented by default
Use the <FILE_HANDLE> construct.

While Ben will do this in one line, here is
how I would handle it.

If you NEED to open the file (rather than STDIN):
\nuse strict;\nopen (IN,"file.dat") or die "Can't open file - $!";\nmy %hash;\nwhile (<IN>){\n  chomp;\n  my ($key,$data) = split(' ',$_,2);\n  $hash{$key} = $data;\n}\nclose (IN);\n
