Jack Schitt writes "In the interest of entertainment and out of sheer curiosity, what is the single most complex batch file(s) you have ever conceived and implemented? When I say complex, I don't mean obfuscated. I mean most amount of work done in a single batch file or series of batch files. (Warning, I'm a former Dos guy, now Windows guy. Batch file can translate to shell script or something similar.)
A good example would be the online bulletin board system I devised for use as a CGI. It implemented rudimentary authentication and administration. It also had email capabilities through something a buddy of mine wrote in c that was akin to sendmail for dos. All of the html was embedded in the batch files though so updating a template was difficult to say the least. Sadly, the code was lost in a house fire before it could make it to a server."
