I'm gonna be a little nit-picky here but for those that asked about net, netstat, nslookup, etc..., They are all external dos commands, ac1d was listing the internal dos commands. Internal dos commands can be used on any dos machine, dependent on version of course. The list that ac1d has created looks to be for winnt, win2k or winxp. Win95 and Win98 didnt contain most of the commands and any dos version before 6 have different internal commands that vary depending on version. Sorry to show my nerdy side but I wanted to point this out to dispel any confusion that some people may have and to make sure people dont get the wrong idea about ac1dsp3ctrum's technical abilities by thinking he didnt list all dos commands. as for flashbacks, who remembers using desk.exe running off of 5 1/4 floppies? or for that fact, who remembers having to type in line after line of code from magazines just to play tic-tac-toe! hehe Enough nostalgia for now!
