the script itself could be stored in $HOME/bin.
this folder does not always exist by default, but if you create it it will probably be added to your $PATH.
excerpt from $HOME/.bash_profile:
Code:
# set PATH so it includes user's private bin if it exists
if [ -d "$HOME/bin" ] ; then
PATH="$HOME/bin:$PATH"
fi
that way you can invoke the script without its full path, just like any other ol' program.
Happy bashing!
