I always get 'function not supported'. Right. mknod is not implemented. That's what the error means. /dev/null is intrinsic to cygwin1.dll. Cygwin programs can use it automatically, just like they can use /dev/tty, /dev/mem, /dev/kmem, etc. cgf -- Want to unsubscribe from this list?

Normally, /dev/null is emulated inside cygwin and you don't need to set it up. I was a little blue-eyed, i made this as a directory, just with windows-explorer, but it didn't solve my problems.

If you need a null file to redirect IN to a command I guess you'd use that. I never try to redirect out to /dev/nul in Cygwin or otherwise, anyway -- although scripts generated by others need to be accomodated.

There is no reason to use 'NUL' rather than '/dev/null' since they are both the same thing ... unless you enjoy using MS-DOS constructs rather than UNIX ones. That's sort of anti-Cygwin, though. cgf -- Want to unsubscribe from this list? Check out: http://cygwin.com/ml/#unsubscribe-simple ^ permalink raw reply [flat|nested] 9+ messages in thread

That's sort of anti-Cygwin, though. NO! NO! I am not anti-Cygwin ;-). I LUV Cygwin. As a background general-knowledge sort of thing, I think its good to know this. Allegory ... if you were stranded on a desert island with no way to buy tiolet paper, would it be good to know how to make plant leaves very soft .. ?

Hopefully these people are reading the appropriate mailing lists and newsgroups for non-cygwin problems, then. In general, I think it is a good idea to use cygwin constructs as much as possible. Then, if/when we modify cygwin so that it can work around the brain-dead, nul, com, aux, prn stupidity foisted on us by Windows' MS-DOS roots, people won't be scratching their heads thinking "But I read that 'NUL' should work fine in the cygwin mailing list." cgf -- Want to unsubscribe from this list?
