Running a shell command from gulp
With gulp 4 your tasks can directly return a child process to signal task completion:
'use strict';
var cp = require('child_process');
var gulp = require('gulp');
gulp.task('reset', function() {
return cp.execFile('git checkout -- .');
});
gulp-v4-running-shell-commands.md
gulp-shell
has been blacklisted. You should use gulp-exec instead, which has also a better documentation.
For your case it actually states:
Note: If you just want to run a command, just run the command, don't use this plugin:
var exec = require('child_process').exec;
gulp.task('task', function (cb) {
exec('ping localhost', function (err, stdout, stderr) {
console.log(stdout);
console.log(stderr);
cb(err);
});
})
The new way to do this that keeps console output the same (e.g., with colors):
see: https://nodejs.org/api/child_process.html#child_process_child_process_spawn_command_args_options
var gulp = require('gulp');
var spawn = require('child_process').spawn;
gulp.task('my-task', function (cb) {
var cmd = spawn('cmd', ['arg1', 'agr2'], {stdio: 'inherit'});
cmd.on('close', function (code) {
console.log('my-task exited with code ' + code);
cb(code);
});
});
