here is a small and simple script, and yet its doing something that i dont understand
On line ten, its giving a "Use of uninitialized value at test.pl line 10." warning.
It seems like all the values are indeed initialized. What am I missing?
#!C:\Perl\bin\perl.exe -w
$file = 'foo.txt';
open(SESAME, $file);
@lines = <SESAME>;
close(SESAME);
$total = @lines;
for ($i=0; $i <= $total; $i++)
{
if ($lines[$i] eq "\n") # This is line the line
{
pop @lines;
$i = $i -1;
$total = @lines;
}
}
print "There are $total records in $file\n";
Use of uninitialized value at test.pl line 10.
