Re: Reading multiple lines?

It's not terribly pretty, but it's cheap:

open FILE, "../data/foo.txt";
@lines    = ($var1,$var2,$var3,$var4,$var5,
           $var6,$var7,$var8,$var9,$var10) =    <FILE>;
close FILE;
print join "\n", @lines;

Got an even better one: `#!/usr/bin/perl my $file = "../data/foo.txt"; my @lines = getFileSlice($file,"10","1"); print join "", @lines; print "\n"; sub getFileSlice() { my $file = shift; my $length = shift; my $offset = shift; my @lines; open FILE, "../data/foo.txt"; for($i=0;$i<$offset;$i++) { <FILE> } for($i=0;$i<$length;$i++) { my $line = <FILE>; push @lines, $line; } close FILE; return @lines; }` [download] -Matthew	[reply] [d/l]

This is even more simple: `open FILE, "../data/foo.txt"; @lines = (<FILE>)[0..9]; close FILE; print "@lines";` [download]	[reply] [d/l]

Well that's the kind of thing which would be nice to write, except I'd probably do it like this :- `@lines[0..9] = <FILE>` ...but it still reads the whole file in (it just throws most of it away). Firstly, that'll use too much memory in this case, and secondly you can't then read the next N lines in. Have fun, rdw	[reply] [d/l]
