Not for me it doesn't.
% bash
bash-3.2$ function f() {
echo hi
}
bash-3.2$ export f
bash-3.2$ bash
bash-3.2$ f
bash-3.2$
I added the 'builtin' command, which did leave the labs. But I added it as
a way for the "whatis" command to show a builtin, as well as allowing a way
to guarantee you get the builtin on execution.
How do I get bash to print the function as (shell) source code, so I could
edit it and play with it again? It was the synergy of all this stuff
connected seamlessly that made it so compelling.
