A handy command line interface for gulp


npm install --save-dev gulp-shell


var gulp  = require('gulp')
var shell = require('gulp-shell')

gulp.task('example', function () {
  return gulp.src('*.js', {read: false})
      'echo <%= f(file.path) %>',
      'ls -l <%= file.path %>'
    ], {
      templateData: {
        f: function (s) {
          return s.replace(/$/, '.bak')

If you just want to execute a series of commands only once, starting the stream with gulp.src('') should do the trick. However, this is an anti-pattern, and it won't work in gulp 4.0 .

Or you can use this shorthand:

gulp.task('shorthand', shell.task([
  'echo hello',
  'echo world'

You can find more examples in the gulpfile of this project.


shell(commands, options) or shell.task(commands, options)


type: Array or String

A command can be a template which can be interpolated by some file info (e.g. file.path).


type: Boolean

default: false

Set to true to print the command(s) to stdout as they are executed


type: String

default: Command `<%= command %>` failed with exit code <%= error.code %>

You can add a custom error message for when the command fails. This can be a template which can be interpolated with the current command, some file info (e.g. file.path) and some error info (e.g. error.code).


type: Boolean

default: false

By default, it will emit an error event when the command finishes unsuccessfully.


type: Boolean

default: false

By default, it will print the command output.


type: Boolean

default: false

Turn it on only if you need to run some interactive commands.


type: String

default: process.cwd()

Sets the current working directory for the command. This can be a template which can be interpolated by some file info (e.g. file.path).


type: Object

The data that can be accessed in template.


type: Number

default: 16MB(16 1024 1024)

You won't need to set this option unless you encounter a "stdout maxBuffer exceeded" error.

For example, setting it to 16 * 1024 * 1024 will result in 16MB.


type: Number

default: undefined (no timeout)

The maximum amount of time in milliseconds the process is allowed to run.


type: Object

By default, all the commands will be executed in an environment with all the variables in process.env and PATH prepended by ./node_modules/.bin (allowing you to run executables in your Node's dependencies).

You can override any environment variables with this option.

For example, setting it to {PATH: process.env.PATH} will reset the PATH if the default one brings your some troubles.
