Source is a command that reads into the environment configuration file and cannot be read into VIMRC

After you finish editing VIMRC, use

SOURCE/ETC/VIMRC Error

-bash:/etc/vimrc:line 15:syntax Error near unexpected token ' "Autocmd" '
-bash:/etc/vimrc:line: ' If has ("Autocmd") '

Thought it was a grammatical problem.

The actual reason: VIMRC is explained when Vim is started, not by the shell. It must not work with the shell to source it.
