So this might surprise you but the commands are actually in the
history list!  But not in the current shell.

What happens is this:

You start 'script foo.txt' and this starts a sub bash shell on a
different pseudo tty.  You run some commands, it appends each command
to the history of this sub-shell's history.

You then exit your script.  Those commands you ran are at the bottom
of .bash_history (try to cat that file out after you exit script and
you should see them).

But those commands are not sucked into the history of your current
shell.  Then, you log out (or exit) your current shell and the history
of that shell overwrites the history of the previous one.

If all you want to do is save off the commands after you exit your
script session, then simply move or copy .bash_history out of the way
before it gets overwritten.

You might consider setting $HISTFILE to some other location other than
.bash_history.
