FYI LWP::Simple can get and print with one command:

perl -MLWP::Simple -e "getprint 'http://www.perlmonks.org'"

Here's a webserver, from the IO::All docs:

perl -MIO::All -e 'io(":8080")->fork->accept->(sub { $_[0] < io(-x $1 
+? "./$1 |" : $1) if /^GET \/(.*) / })'

One line web server? Way cool.

A couple of years ago I went back to uni for a network communication class I failed once. After completing the lab assignment of writing a "time-of-day" server in C, I showed the lab instructor the equivalent perl code (one-liner). He thought it was pretty cool (I know, the lab goal is not the end result, but the methods you use to get there, but still..)

Had I known about IO::All and one-line web servers at the time, I might have gotten extra points on the lab assignment :)
