cd // ????

I did this by accident and it actually took me to a directory with nothing in it. cd .. took me to root.

I did it in cygwin and did a listing, and it listed a file called 'hurricane' (after a significant delay) but couldn't access it. cd .. left me in the directory // though.

What's going on here?

hurricane is the name of your Windows computer. On real Unixes, cd // should just take you to /.

in cygwin and MinGW using cd to \\ ( or //) will take you to thew MS Windows C drive ( the default )

but this also depends on what you have listed in the "/etc/profile "
for ex in mingw or cygwin if i do this"
cd /src" i go to
C:\\ GnwWin32/Mingw/src

and if i do this
cd /
i go to
C:\\GnuWin32/Msys/home/john

what did you set the files to ???

I've mostly satisfied my curiosity here. I don't know why a Linux computer would want to take you to root when you go to // but call it // instead of just / ...some kind of backwards compatibility I guess?

hurricane is actually not the network name of my windows computer, but I have a vague memory of putting that in somewhere. It doesn't really matter, I was just curious.

I looked in etc profile briefly, but didn't find any lines relating to this. Again, it doesn't really matter I was just curious.

Probably just convenience. "//" anywhere in a path cannot be valid so most (all?) programs simply silently treat it as "/". Hey -- we bad typists need all the help we can get!
