in reply to File Handles Chapter(not homework)

To read a file line by line, you typically use
while (my $line = <>) { # do something with the line }
If this construct is missing in your textbook, somebody probably tore some pages from the book.

If you meant "preceded" by "proceded", you might use $ARGV: look it up in perlvar.

[ambrus]: Today I accidentally cut my hand while carrying a computer. On the display part of the motherboard that sticks out at the back of the chasis and has ports, there's this thin metal sheet with holes cut for the ports, to guide plugs into the sockets.
[ambrus]: This sheet has sharp needle-like parts, 0.004 long and less than 0.001 wide, that can get bent to point outwards, and one of these cut into my palm when I lifted the box.
[ambrus]: So now when I choose what motherboard to buy for my new home computer, I have one more specific property to guide me. Useful, because there's so many different boards to choose from.
