in reply to Reading entire file.

I'll just latch onto one of your questions:

>Is there an easier way to test and print between two points in a file,

Yes, there is. I tried to explain it in from...to

In your case, I'd recommend you break out of the loop after you're finished with the tool:

while (<FOO_FILE>){ if (/$foo/){ $that = 1; } if (/$bar/){ last; # emergency exit from the loop ;-) } if ($that){ print $_; } }

You could also seperate it into two loops, one for searching for the tool, one for reading the lines for that tool.

while (<FOO_FILE>){ last if /$foo/; # ignore all lines until we find foo } while (<FOO_FILE>){ last if /$bar/; print $_; # do something with the lines we find now } close FOO_FILE; # just ignore the rest of the file

      I'll ask vroom to unreap this node. The reply was exactly what I was thinking when I read the node that it was a reply to.

      I'm disappointed in azatoth for asking for it to be reaped just because s/he didn't understand its criticism. And I'm ashamed that it ended up getting reaped!

      Please only reap obvious trolls and complete duplicates!
