Can I find the value of -c "string" in ksh?
|

| In ksh, I want to find the value of the command string used by someone
invoking the shell with the -c argument.
For example, just suppose someone invoked my shell like this:
/bin/ksh -l -c "echo hi"
Now, in my ~/.profile (which is read because of the -l option) I'd like
to find out what the command script given to the -c argument was (here,
"echo hi").
I've already tried "$@" and reading stdin; no joy. The shell must stash
that away somewhere else before it starts to run my ~/.profile. Can I
get this information back out?
Please don't tell me how to do it in bash or zsh, or that I should
switch shells, etc.: I need it in ksh, and there's nothing I can do
about it for now.
Thanks!

Mmm. ps. One of the LEAST portable UNIX commands ever written :-/.
OK, I can work with that, I guess, if there's no way to get that string
directly. Thanks.
