How to run another shell and have all current shell dectaration copied to that new shell?

I would like to have available all current declarations in a new shell. That are functions, aliases, variables.
Possible but not easily done. Think about it, opens up all sorts of security issues.

BTW, most test suites use a combination of TCL and expect to test shell scripts.

How about:
Code:
$ declare > my_declarations
$ bash
$ source my_declarations

I'm not sure that's what you're looking for, but it might work... dunno

*EDIT:
no... don't even bother... declare doesn't store alias declarations

Works for me, but I guess you will have to set -a before you declare the ones you want exported.

Code:
vnix$ PS1='nst> '
nst> set -a
nst> fnord=foo
nst> foo () { echo foo; }
nst> alias bar='echo bar'
nst> bash
vnix$ echo "$fnord"
foo
vnix$ foo
foo
vnix$ bar
bash: bar: command not found
vnix$ exit
nst> exit
