For completeness (though someone correct me if I'm remembering incorrectly), this hack is a typical DOS idiom, but ... 1). It doesn't work under WinXP's CMD.EXE (etc.) 2). DR-DOS' shell prefers "direxist" 3). 4DOS supports both "direxist" and "isdir" Timo Salmi had some good .BAT (and .CMD) FAQs back in the day. I should really email him to ask him for permission to mirror them (not sure if they are technically free/libre or not), esp. since Garbo went kaput. EDIT: Err, maybe not. :-( http://lipas.uwasa.fi/~ts/garbo.html http://www.netikka.net/tsneti/info/tscmd.php " An important note to Garbo repository users: The workstation hosting the Garbo repository at the University of Vaasa, Finland has broken down during 2012. The university's Computer Centre has informed me that it will not be replaced. Thus all the potentially remaining direct references to the utilities at Garbo in this FAQ are out of date. However, tscmd.zip continues to be available, now at a private ISP address. You may freely download it for your own, private purposes. But contrary to some past Garbo exceptional arrangements, I do not give permissions to mirroring, that is carrying my materials for downloading at other locations. (I am retired, fully served, since September 2011. I now say routinely no to all requests.) " Well, no huge loss, as long as he still mirrors it online. ------------------------------------------------------------------------------ Free Next-Gen Firewall Hardware Offer Buy your Sophos next-gen firewall before the end March 2013 and get the hardware for free!
