[code elided] Don't do it. Check the following two modules: Socket and LWP. Socket takes care of all the machine-specific things, so you don't need to do Evil Pernicious Hard Coding of Constants. The LWP library contains everything you'd need to do what you want. How about: perl -MLWP::Simple -e 'getprint "http://www.whatever.com"' > junk as a oneliner that does the job. And, of course, there are oodles of more complex things you can do. Modules are available via CPAN, which you can find at . Look for Software, then the "full modules list". Browse that, seach for LWP and Socket, and follow links to the software. -Dean -- N.
