Updating the KSH Environment

To update your ksh environment after making some changes
to your ~/.profile from your home directory, ~/ do:

. ./.profile

That'll refresh the environment. For instance, when you
add an alias to your .profile with an editor rather than
exporting something the environment which will only last
for that session. Just remember that first . It looks a
little different than like when you run a script as:

./script.sh

but it'll deny you permission to execute if you forget it
and just type ./profile
