I don't think you've tried hard enough.  :)


open TEST, ">test.txt";

print TEST "this is  a test\n";

open TEST, "test.txt";
my $l = <TEST>;
print "TEST before edit: $l";

open TEST, "+<test.txt";

seek TEST, 5, 0;

print TEST "was";

open TEST, "test.txt";
$l = <TEST>;
print "TEST after edit: $l";
