Those crazy open source developers have an implementation here: http://cvs.sourceforge.net/viewcvs.py/mkcdrec/mkcdrec/busybox-0.60.5/Attic/tail.c?rev=1.1&view=markup It's not documented. It's pretty short though, I'm sure you won't have any problems <strike>ripping it to pieces</strike> understanding it. If it is a problem, a more documented version here (however I'm sorry, this also by those open source/free software people you love to attack): http://www.koders.com/c/fid8DEE98A42C35A1346FA89C328CC3BF94E25CF377.aspx If you want something not by open source crazies (as you like to refer to us), you may prefer this link: http://minnie.tuhs.org/UnixTree/V7/usr/src/cmd/tail.c.html However that's even less documented (despite being not open source, just "visible"), and more obfuscated. As a compromise, you could always look at plan 9's implementation here: * http://swtch.com/usr/local/plan9/src/cmd/tail.c If you're after alternatives, you could always try here: (where all these links came from) http://www.google.com/search?q=tail.c Fairly informative set of links provided by that highly non-obvious search.... Hope that helps, Best Regards, Michael. -- http://mail.python.org/mailman/listinfo/python-list
