Regarding my "ls: .: No such file or directory" problem I had posted a few
days ago:
When I cd to "//c", I can do 'ls' just fine. When I cd to "c:/" I have the
above mentioned problem. When I try to cd to "/cygdrive/c", it won't go
there as it says that there's no such file or directory. Apparently it
doesn't recognize "/cygdrive". However, when I do a 'mount', it shows the
mounts ok:
==============================================================
tmp@PCDEV1A /home
$ cd /cygdrive/c
bash: cd: /cygdrive/c: No such file or directory
tmp@PCDEV1A /home
$ cd c:
tmp@PCDEV1A c
$ ls
ls: .: No such file or directory
tmp@PCDEV1A c
$ cd //c
tmp@PCDEV1A //c
$ ls

C:\cygwin / system binmode

==============================================================
Any ideas? Thanks again for any help!

Bash is a UNIX shell. Why not using UNIX paths? Actually not
C:/ is deprictaed but //c! The syntax is ambiguous since that
could also address a SMB server. We may decide to eliminate
that syntax for local drives completely in the future. Use
the /cygdrive/c syntax instead.
