gulp-delete-file

$3

Initially, install gulp-delete-file as a development dependency:

``
npm install --save gulp-delete-file
`
Then, create task using gulp-delete-file, which might look similar as below:

`
'use strict';
var gulp = require('gulp'),
deletefile = require('gulp-delete-file');
gulp.task('deletefile', function () {
var regexp = /\w(\-\w{8}\.js){1}$|\w(\-\w{8}\.css){1}$/;
gulp.src(['./build/public/train/*/.js',
'./build/public/train/*/.css',
'./build/public/train/*/.scss',
'./build/public/train/*/.less'
]).pipe(deletefile({
reg: regexp,
deleteMatch: false
}))
});

`

Finally, fire gulp task:

`
gulp deletefile

`

reg：is a RegExp Object

deleteMatch:if the value is 'true',then the command will delete all the files which match the reg-rule. if it is 'false',then delete all the files which doesn't match the reg-rule.
