building tables with script files in mac os x

I'm trying to figure out how to run scripts against MySQL to create
tables, insert data into tables, etc. I've created a folder within my
'Documents' folder for all of my MySQL scripts. However, when I issue
the command:
source /Panther/Users/xxxxxxxx/Documents/MySQL/Invoices.txt' or
\. /Panther/Users/xxxxxxx/Documents/MySQL/Invoices.txt

I get the error message:

ERROR:
Failed to open file '/Panther/Users/xxxxxxxx/Documents/MySQL/
Invoices.txt/', error: 2

What am I doing wrong?
