I'd like to be able to know mid-working what directory a child process started in.
Here I'm in a Bash session, I start a dash session and I'd like to know where did dash start (in the example it would be /home).
$ echo $PWD
/home
$ dash
$ cd .. && echo $PWD
/ #Here I was hoping it would print /home
exit
echo $PWD
/home #And the shell somehow knew where to get back to
How do I do this?

If you don't callcd ..first, then it would print/home.

@ctrl-alt-delor Yes, you missed my point. I start dash, I do a bunch of stuff and change directories a bunch of times, I want to know where the process as initiated.

Addinitial_pwd="$PWD"to the start. Note this is not the same as the directory containing the script.

Alas that doesn't help me because the child session I'm in always starts in the home directory, regardless of where the child started. I really need to know where the child shell initiated.
