Thanks for the suggestion.  I understand what you do but in my case I
don't prepare the shell scripts but they come as a part of software
development kit from system silicon vendors.  I used to hand translate
those shell scripts into custom elisp functions like you show below
but that soon got too cumbersome to maintain for multiple platforms.
What I want to automate is the following process without loosing the
currently opened buffers.

M-x kill-emacs
$ source env-xxx.sh
$ emacs
