Agreed. Perderabo is correct.

...from the bash man page regarding dot "." notation or
"source"ing...

. filename [arguments]
source filename [arguments]
Read and execute commands from filename in the cur-
rent shell environment and return the exit status
of the last command executed from filename. If
filename does not contain a slash, pathnames in
PATH are used to find the directory containing
filename. The file searched for in PATH need not
be executable. The current directory is searched
if no file is found in PATH. If any arguments are
supplied, they become the positional parameters
when file is executed. Otherwise the positional
parameters are unchanged. The return status is the
status of the last command exited within the script
(0 if no commands are executed), and false if file-
name is not found.
