For a bit more detail:
#It ends up:
$gr = "tcp";
$pm = "127.0.0.1";
$org = "13";
tcp is the protocol, 127.0.01 is the IP address which maps
to localhost (your box). 13 is the port number to connect to -
port 13 is where the daytime service is on most U*IX machines.
$stuff creates a socket connection to the local box on port
13, and the while loop prints the output, which is a POSIX-style
datetime.
Both Joel and David pointed out that some U*IX boxes
have this service disabled, but it worked on Happyfunball. ;-)
Joel also pointed out the security risks of having services
like this enabled. Think we should have a meeting on
security?
see you next month,
