Whew! I'm glad I'm not the only one who didn't realize BASH was handling these on systems where there's no std* files in /dev. On my SuSE 8.1 (kernel 2.4.19), /dev/std{in,out,err} are symbolic links to fd/{0,1,2} (where /dev/fd is a symbolic link to /proc/self/fd). >Oh, you'll like this one: "Learn Linux in 15 minutes a week!": >http://www.2000trainers.com/article.aspx?articleID=144&page=2 > >Says /dev/std{in|err|out} are standard on linux systems. >Maybe Cygwin should be renamed "CyNUX": "Cygwin is Not >Unix or Linux"? :-) Maybe "CygNoX?" The lore could be that it's closely related to the well known air pollutants NOx but with the primary toxic and polluting effects on the infosphere, not the atmosphere. Or maybe it could be said to stand for the "Cygwin school of hard nox? >I guess the author of 'makewhatis' didn't know this either. Perhaps >it's on enough systems. That's the great thing about standards. There are so many to choose from (and assume).
