Can Gulp overwrite all src files?

I can think of two solutions:

1. Add an option for base to your gulp.src like so:

   gulp.src([...files...], {base: './'}).pipe(...)...
   

   This will tell gulp to preserve the entire relative path. Then pass './' into gulp.dest() to overwrite the original files. (Note: this is untested, you should make sure you have a backup in case it doesn’t work.)

2. Use functions. Gulp’s just JavaScript, so you can do this:

   [...files...].forEach(function(file) {
       var path = require('path');
       gulp.src(file).pipe(rename(...)).pipe(gulp.dest(path.dirname(file)));
   }
   

   If you need to run these asynchronously, the first will be much easier, as you’ll need to use something like event-stream.merge and map the streams into an array. It would look like

   var es = require('event-stream');
   
   ...
   
   var streams = [...files...].map(function(file) {
           // the same function from above, with a return
           return gulp.src(file) ...
       };
   return es.merge.apply(es, streams);
