Sorry, but it works for me even if I set the CDPATH in ~/.bashrc

In ~/.bashrc
# CDPATH
CDPATH=.:/home/<USERNAME>/1/2/
export CDPATH

Open xterm
echo $CDPATH --> .:/home/<USERNAME>/1/2/
emacs -q <RET>
M-x shell <RET>
In shell
cd <RET>
echo $CDPATH --> .:/home/<USERNAME>/1/2/
cd 3 <RET>
pwd -- > /home/<USERNAME>/1/2/3


Ditto for eshell.

However in eshell the sequence of commands
cd <RET>
cd 3 <RET>
cd ../ <RET>
ls --> /HOME
cd ../ <RET>
ls --> /<USERNAME>
cd <RET>
ls --> all files and directories in $HOME are listed as normal

The odd behaviour of eshell does not occur in shell.

Again, I'm using emacs-28.0.50

Best wishes,

Colin.
