RE: Unexpected behavior of ~ when calling bash from a different cygwin installation




Dear Cygwin Users,

I got it, I just have to clear the HOME variable before.

But I have a few more observations on this:

the FAQ (section 4.20) state that the root path for the mount table depends on the path of the cygwin1.dll, to which an executable is linked. This doesn't seem to be the case. E.g. when I do

* start a bash via C:\bin\cygwinA\cygwin.bat 
* cd to /cygdrive/c/bin/cygwinB/bin
* ./bash

The first and the second bash have both /=C:\bin\cygwinA although SysInternals ProcExplorer clearly shows that the second bash loads the cygwin1.dll from C:\bin\cygwinB and not from C:\bin\cygwinA. Is there some description on how the path mapping really works?

If I do:

* start a bash via C:\bin\cygwinA\cygwin.bat 
* cd to /cygdrive/c/bin/cygwinB/bin
* /cygdrive/c/Windows/System32/cmd
* bash

The dlls to which the second bash links are the same in both cases, but in the second case /= C:\bin\cygwinB in the second shell.

And yes, I also read in section 4.20 of the FAQ that one shouldn't call one Cygwin from another. But I think a clear handover from one bash to another should work in a documented way.

Best regards,

Michael
