Re: 1.7.25: problem with the cd command in ksh

[Francis ANDRE <francis dot andre at easynet dot fr>]

Hi Robert

The problem here is that the string of the target directory is computed by
another tool -- Mercurial in this case -- and that Mercurial returns a absolute
windows style path as

Z:/DEV/OpenJDK_7u40/hotspot

which seems to be relative in Unix world but which is absolute in the Windows
world.


Moreover, when using the bash shell, the command

FrancisANDRE@idefix /cygdrive/c/Cygwin
$ cd Z:/DEV/OpenJDK_7u40/hotspot

moves the cwd without error to
FrancisANDRE@idefix /cygdrive/z/DEV/OpenJDK_7u40/hotspot


So why the ksh cannot do the same?
