How about a "random file" of 5 MB?

(yes I know this is some ugly Perl)

#!/usr/bin/perl

@dirs = `find ~/* -type d`;

my $dir = $dirs[ rand( @dirs ) ];
chomp $dir;

my $numChars = int( rand( 12 ) ) + 1;
my $extChars = int( rand( 12 ) ) + 1;

my $file = "";

for( 1..$numChars ) { $file .= (a..z)[ rand( 24 ) ]; }
$file .= ".";
for( 1..$extChars ) { $file .= (a..z)[ rand( 24 ) ]; }
my $file = $dir."/".$file;

open( OUT, ">".$file );
for( 1..5000000 ) { print OUT "."; }
close( OUT );
print "wrote 5 million chars to $file.\n";

exit( 0 );
