Perform substitution with macros and repeat it

While recording a macro, perform substitution on one file, and repeat the macros across all args.

Assuming the same folder structure and args, here is how it is done:

qq                                          // start macro in q register
%s/stringToBeReplaced/replacementString/ge  // the e flag tells vim to not throw an error if there is no match
:wnext                                      //important. This is similar to `:next`, but it also writes the current file
q                                           // stop macro
999@q                                       //repeat this macros either 999 times or to remaining files.

That's it!
