How to send in a string into a Gulp task?

Question

This is step 1 in creating versioned folders for my deployment builds.

How would it be possible to pass in a string into the gulp.task below?

gulp.task('build', function(cb) {
    runSequence('html-templates',
                'stx-css',
                'app-css',
                'stx-js',
                'app-js',
                'build:copy',
                'build:remove',
                'build:index', cb);
});

I'd like to do something like this: gulp build 1.0.1 which will then pass the string 1.0.1 into the Gulpfile.

gulp.task('build', function(version, cb) {
    console.log('version = ', version);
    runSequence('html-templates',
                'stx-css',
                'app-css',
                'stx-js',
                'app-js',
                'build:copy',
                'build:remove',
                'build:index', cb);
});

This can be accomplished using the env variable!

Great video on the subject: https://www.youtube.com/watch?v=gRzCAyNrPV8

So I added this to my Gulpfile:

var env = process.env.V; // V={version number}

And then added a version task, which calls a function to print out a string that I pass in before calling my build task:

gulp.task('build', function(cb) {
    runSequence('version',
                'html-templates',
                'stx-css',
                'app-css',
                'stx-js',
                'app-js',
                'build:copy',
                'build:remove',
                'build:index', cb);
});

gulp.task('version', function() {
    return printOut(env);
});

function printOut(version) {
    console.log('version = ',version);
}
