Wrong!

./spgs_profile   # executes the script in a new shell (child process).

. ./spgs_profile  # whereas this command sources the script in the 
                             # current shell.

In Bash and Csh, you can also use the command 'source ./spgs_profile' 
instead to achieve the same effect.
