lol, I'm going to give the third different solution to this problem.
# Create a binary directory for your own scripts. This is common in almost
# all unix systems and is about the only way to easily get it working when
# you don't have root access (and it is a good idea anyway to keep user
# scripts away from the system utilities).
mv /path/to/script ~bin/
# Check your path and make sure $HOME/bin is in it. On most systems,
# this is the case (as this solution is so common that most systems are
# setup expecting users to add programs to $HOME/bin).
# If it isn't run:
PATH=$PATH:$HOME/bin; export PATH
And remember to add it to .profile where your path is listed.
