bash builtin pwd returns Windows style names

bash builtin pwd returns Windows style names

[Richter Norbert]

Hello,

I observed that in previous releases of Cygwin (I think it was 1.3.12) the
bash builtin
pwd returned directory names in the form:
/cygdrive/c/classes

but if I try this now with the release 1.3.14 (and also with 1.3.15 and bash
2.05b) I get
c:/classes

I wonder if this has been intentionally changed, and if so, whether it is
possible to configure it either way.

Thanks in advance for comments on this,

Norbert Richter

Try doing a "cd c:/tmp" or something similar.  Bash will dutifully report
that you are in the c:/tmp directory at that point.

Ok. That's a bash problem.  It doesn't recognize c: as a drive but as
the beginning of a relative path.

This is weird since bash has special handling for drive letters under
Cygwin in lib/sh/pathcanon.c, function sh_canonpath().  For some reason
it just doesn't work...

Chet?  Do you have an idea how to solve that?

Start looking at it with a debugger.

The bash function absolute_pathname() should report that c:/tmp is absolute.
If it succeeds, set a breakpoint in change_to_directory() and see what it's
doing.

I'm not on the cygwin mailing list, and can't provide any debugging
assistance right now, so contact me directly if you have more questions.

Hi,

thank you, Corinna, for this hint. It works also with me.

However, if you do

bash-2.05b$ uname -a
CYGWIN_NT-5.0 PC4265 1.3.15(0.63/3/2) 2002-11-07 13:57 i686 unknown
bash-2.05b$ cd c:/tmp
bash-2.05b$ pwd
c:/tmp
bash-2.05b$ /bin/pwd
/cygdrive/c/tmp

Cygwin/bash does not recognize c:/tmp as a windows path name. I am not sure,
if 
it is supposed to do, but perhaps you can tell me.

If you do however

bash-2.05b$ cd 'c:\tmp'
bash-2.05b$ pwd
/cygdrive/c/tmp

the pathname c:\tmp is recognized as windows pathname and implicitely
converted.

Thanks for your help,

Regards, Norbert
