in thread Perl program to search files
Minor note:
A typical solution to this kind of problem would be to implement a sliding window
But he is trying to slide:
$START += $BUFF_SIZE - length($FIND);Unfortunately, it seems that his 4th argument to read is understood as "offset into file", while, of course, it is "offset into buffer". If this
read $F, $BUFFER, $BUFF_SIZE, $START;is replaced with
seek $F, $START, 0; read $F, $BUFFER, $BUFF_SIZE;
then his sliding window works.
