I won't go into the gory details of all the bugs in path handling and the intricacies of quoting, but the following should work for you: bash: $ dd if='\\.\a:' of=somewhere NT cmd: c:\>dd "if=\\.\a:" of=somewhere If you get those quotes mixed up, I take no responsibility for the consequences. For those looking to access a tape drive this way, forget it. The path to the tape drive is "\\.\TAPE0". Since that doesn't contain a ':', cygwin.dll blithely, buggily, turns it into "//TAPE0". The solution? Rewrite path.cc (not to mention the rest of cygwin.dll). In the meantime, it's easy enough to write a little pgm that calls CreateFile and then pipe it into dd or cpio or whatever. This is all for NT, of course. For those of you using Windows 95: I feel your pain. -- - For help on using this list, send a message to "gnu-win32-request@cygnus.com" with one line of text: "help".
