Is this right?

quote:

---

open(FILE1,"open(FILE2,">/file-temp.txt"); # Write
@line = ;

for ($i=0;$i<$#line+1;$i++) {
chomp($line[$i]);
if ( $LineToChange ) {
print FILE2 "$line[$i]";
} else {
print FILE2 "$line[$i]";
}
}

close(FILE1);
close(FILE2);

Someone helped me with this and I'm not entirely accurate what "$i" is.. what is it?

If thise won't work, please post another for me.

$i is a variable. it isnt declared before the for loop, so its value is zero. you create a loop for the valus of $i

if $#line+1 is equal to 10 $i is defined like this;
0<= $i < 10

first $i = 0 then you add +1 to its value in the loop to reach the number 10
