In sh and ksh (and probably bash), you can list exported variables with
$ export
with no args.
In ksh
$ export variable=value
will work in one command. In sh, I think you would have to
$ variable=value; export variable
which is two commands.
I haven't checked bash, but it has a lot of ksh tendencies so you see
the possibilities for checking it out. === Al
