There is no difference between . and source commands there are synonymous
Extract from bash man page
. filename [arguments]
source filename [arguments]
Read and execute commands from filename in the current shell
environment and return the exit status of the last command executed from
file‐
name. If filename does not contain a slash, file names in
PATH are used to find the directory containing filename. The file searched
for
in PATH need not be executable. When bash is not in posix
mode, the current directory is searched if no file is found in PATH. If
the
sourcepath option to the shopt builtin command is turned
off, the PATH is not searched. If any arguments are supplied, they become
the
positional parameters when filename 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 filename is not found or cannot be read.
