Vim 002: Submitting Vim Command from the shell

A Vim command can be submitted to Vim directly from the shell (without entering Vim) by calling:

vi "+:%s/+0/+1/g" "+wq" $i

Notice the '+' operator within the command string. Also notice the 'wq' command to save and "exit" Vim once it finished its job. This is an excellent way of processing a batch of files.
