Introduction
Artisan is the command line interface included with Laravel. Artisan exists at the root of your application as the artisan
script and provides a number of helpful commands that can assist you while you build your application. To view a list of all available Artisan commands, you may use the list
command:
php artisan list
Every command also includes a "help" screen which displays and describes the command's available arguments and options. To view a help screen, precede the name of the command with help
:
php artisan help migrate
Laravel Sail
If you are using Laravel Sail as your local development environment, remember to use the sail
command line to invoke Artisan commands. Sail will execute your Artisan commands within your application's Docker containers:
./vendor/bin/sail artisan list
Tinker (REPL)
Laravel Tinker is a powerful REPL for the Laravel framework, powered by the PsySH package.
Installation
All Laravel applications include Tinker by default. However, you may install Tinker using Composer if you have previously removed it from your application:
composer require laravel/tinker
Note

Usage
Tinker allows you to interact with your entire Laravel application on the command line, including your Eloquent models, jobs, events, and more. To enter the Tinker environment, run the tinker
Artisan command:
php artisan tinker
You can publish Tinker's configuration file using the vendor:publish
command:
php artisan vendor:publish --provider="Laravel\Tinker\TinkerServiceProvider"
Warning
Thedispatch
helper function anddispatch
method on theDispatchable
class depends on garbage collection to place the job on the queue. Therefore, when using tinker, you should useBus::dispatch
orQueue::push
to dispatch jobs.
Command Allow List
Tinker utilizes an "allow" list to determine which Artisan commands are allowed to be run within its shell. By default, you may run the clear-compiled
, down
, env
, inspire
, migrate
, optimize
, and up
commands. If you would like to allow more commands you may add them to the commands
array in your tinker.php
configuration file:
'commands' => [
// App\Console\Commands\ExampleCommand::class,
],
Classes That Should Not Be Aliased
Typically, Tinker automatically aliases classes as you interact with them in Tinker. However, you may wish to never alias some classes. You may accomplish this by listing the classes in the dont_alias
array of your tinker.php
configuration file:
'dont_alias' => [
App\Models\User::class,
],
Writing Commands
In addition to the commands provided with Artisan, you may build your own custom commands. Commands are typically stored in the app/Console/Commands
directory; however, you are free to choose your own storage location as long as your commands can be loaded by Composer.
Generating Commands
To create a new command, you may use the make:command
Artisan command. This command will create a new command class in the app/Console/Commands
directory. Don't worry if this directory does not exist in your application - it will be created the first time you run the make:command
Artisan command:
php artisan make:command SendEmails
Command Structure
After generating your command, you should define appropriate values for the signature
and description
properties of the class. These properties will be used when displaying your command on the list
screen. The signature
property also allows you to define your command's input expectations. The handle
method will be called when your command is executed. You may place your command logic in this method.
Let's take a look at an example command. Note that we are able to request any dependencies we need via the command's handle
method. The Laravel service container will automatically inject all dependencies that are type-hinted in this method's signature:
<?php
namespace App\Console\Commands;
use App\Models\User;
use App\Support\DripEmailer;
use Illuminate\Console\Command;
class SendEmails extends Command
{
/**
* The name and signature of the console command.
*
* @var string
*/
protected $signature = 'mail:send {user}';
/**
* The console command description.
*
* @var string
*/
protected $description = 'Send a marketing email to a user';
/**
* Execute the console command.
*/
public function handle(DripEmailer $drip): void
{
$drip->send(User::find($this->argument('user')));
}
}
Note
For greater code reuse, it is good practice to keep your console commands light and let them defer to application services to accomplish their tasks. In the example above, note that we inject a service class to do the "heavy lifting" of sending the e-mails.
Closure Commands
Closure based commands provide an alternative to defining console commands as classes. In the same way that route closures are an alternative to controllers, think of command closures as an alternative to command classes. Within the commands
method of your app/Console/Kernel.php
file, Laravel loads the routes/console.php
file:
/**
* Register the closure based commands for the application.
*/
protected function commands(): void
{
require base_path('routes/console.php');
}
Even though this file does not define HTTP routes, it defines console based entry points (routes) into your application. Within this file, you may define all of your closure based console commands using the Artisan::command
method. The command
method accepts two arguments: the command signature and a closure which receives the command's arguments and options:
Artisan::command('mail:send {user}', function (string $user) {
$this->info("Sending email to: {$user}!");
});
The closure is bound to the underlying command instance, so you have full access to all of the helper methods you would typically be able to access on a full command class.
Type-Hinting Dependencies
In addition to receiving your command's arguments and options, command closures may also type-hint additional dependencies that you would like resolved out of the service container:
use App\Models\User;
use App\Support\DripEmailer;
Artisan::command('mail:send {user}', function (DripEmailer $drip, string $user) {
$drip->send(User::find($user));
});
Closure Command Descriptions
When defining a closure based command, you may use the purpose
method to add a description to the command. This description will be displayed when you run the php artisan list
or php artisan help
commands:
Artisan::command('mail:send {user}', function (string $user) {
// ...
})->purpose('Send a marketing email to a user');
Isolatable Commands
Warning To utilize this feature, your application must be using the
memcached
,redis
,dynamodb
,database
,file
, orarray
cache driver as your application's default cache driver. In addition, all servers must be communicating with the same central cache server.
Sometimes you may wish to ensure that only one instance of a command can run at a time. To accomplish this, you may implement the Illuminate\Contracts\Console\Isolatable
interface on your command class:
<?php
namespace App\Console\Commands;
use Illuminate\Console\Command;
use Illuminate\Contracts\Console\Isolatable;
class SendEmails extends Command implements Isolatable
{
// ...
}
When a command is marked as Isolatable
, Laravel will automatically add an --isolated
option to the command. When the command is invoked with that option, Laravel will ensure that no other instances of that command are already running. Laravel accomplishes this by attempting to acquire an atomic lock using your application's default cache driver. If other instances of the command are running, the command will not execute; however, the command will still exit with a successful exit status code:
php artisan mail:send 1 --isolated
If you would like to specify the exit status code that the command should return if it is not able to execute, you may provide the desired status code via the isolated
option:
php artisan mail:send 1 --isolated=12
Lock ID
By default, Laravel will use the command's name to generate the string key that is used to acquire the atomic lock in your application's cache. However, you may customize this key by defining an isolatableId
method on your Artisan command class, allowing you to integrate the command's arguments or options into the key:
/**
* Get the isolatable ID for the command.
*/
public function isolatableId(): string
{
return $this->argument('user');
}
Lock Expiration Time
By default, isolation locks expire after the command is finished. Or, if the command is interrupted and unable to finish, the lock will expire after one hour. However, you may adjust the lock expiration time by defining a isolationLockExpiresAt
method on your command:
use DateTimeInterface;
use DateInterval;
/**
* Determine when an isolation lock expires for the command.
*/
public function isolationLockExpiresAt(): DateTimeInterface|DateInterval
{
return now()->addMinutes(5);
}
Defining Input Expectations
When writing console commands, it is common to gather input from the user through arguments or options. Laravel makes it very convenient to define the input you expect from the user using the signature
property on your commands. The signature
property allows you to define the name, arguments, and options for the command in a single, expressive, route-like syntax.
Arguments
All user supplied arguments and options are wrapped in curly braces. In the following example, the command defines one required argument: user
:
/**
* The name and signature of the console command.
*
* @var string
*/
protected $signature = 'mail:send {user}';
You may also make arguments optional or define default values for arguments:
// Optional argument...
'mail:send {user?}'
// Optional argument with default value...
'mail:send {user=foo}'
Options
Options, like arguments, are another form of user input. Options are prefixed by two hyphens (--
) when they are provided via the command line. There are two types of options: those that receive a value and those that don't. Options that don't receive a value serve as a boolean "switch". Let's take a look at an example of this type of option:
/**
* The name and signature of the console command.
*
* @var string
*/
protected $signature = 'mail:send {user} {--queue}';
In this example, the --queue
switch may be specified when calling the Artisan command. If the --queue
switch is passed, the value of the option will be true
. Otherwise, the value will be false
:
php artisan mail:send 1 --queue
Options With Values
Next, let's take a look at an option that expects a value. If the user must specify a value for an option, you should suffix the option name with a =
sign:
/**
* The name and signature of the console command.
*
* @var string
*/
protected $signature = 'mail:send {user} {--queue=}';
In this example, the user may pass a value for the option like so. If the option is not specified when invoking the command, its value will be null
:
php artisan mail:send 1 --queue=default
You may assign default values to options by specifying the default value after the option name. If no option value is passed by the user, the default value will be used:
'mail:send {user} {--queue=default}'
Option Shortcuts
To assign a shortcut when defining an option, you may specify it before the option name and use the |
character as a delimiter to separate the shortcut from the full option name:
'mail:send {user} {--Q|queue}'
When invoking the command on your terminal, option shortcuts should be prefixed with a single hyphen and no =
character should be included when specifying a value for the option:
php artisan mail:send 1 -Qdefault
Input Arrays
If you would like to define arguments or options to expect multiple input values, you may use the *
character. First, let's take a look at an example that specifies such an argument:
'mail:send {user*}'
When calling this method, the user
arguments may be passed in order to the command line. For example, the following command will set the value of user
to an array with 1
and 2
as its values:
php artisan mail:send 1 2
This *
character can be combined with an optional argument definition to allow zero or more instances of an argument:
'mail:send {user?*}'
Option Arrays
When defining an option that expects multiple input values, each option value passed to the command should be prefixed with the option name:
'mail:send {--id=*}'
Such a command may be invoked by passing multiple --id
arguments:
php artisan mail:send --id=1 --id=2
Input Descriptions
You may assign descriptions to input arguments and options by separating the argument name from the description using a colon. If you need a little extra room to define your command, feel free to spread the definition across multiple lines:
/**
* The name and signature of the console command.
*
* @var string
*/
protected $signature = 'mail:send
{user : The ID of the user}
{--queue : Whether the job should be queued}';
Prompting For Missing Input
If your command contains required arguments, the user will receive an error message when they are not provided. Alternatively, you may configure your command to automatically prompt the user when required arguments are missing by implementing the PromptsForMissingInput
interface:
<?php
namespace App\Console\Commands;
use Illuminate\Console\Command;
use Illuminate\Contracts\Console\PromptsForMissingInput;
class SendEmails extends Command implements PromptsForMissingInput
{
/**
* The name and signature of the console command.
*
* @var string
*/
protected $signature = 'mail:send {user}';
// ...
}
If Laravel needs to gather a required argument from the user, it will automatically ask the user for the argument by intelligently phrasing the question using either the argument name or description. If you wish to customize the question used to gather the required argument, you may implement the promptForMissingArgumentsUsing
method, returning an array of questions keyed by the argument names:
/**
* Prompt for missing input arguments using the returned questions.
*
* @return array
*/
protected function promptForMissingArgumentsUsing()
{
return [
'user' => 'Which user ID should receive the mail?',
];
}
You may also provide placeholder text by using a tuple containing the question and placeholder:
return [
'user' => ['Which user ID should receive the mail?', 'E.g. 123'],
];
If you would like complete control over the prompt, you may provide a closure that should prompt the user and return their answer:
use App\Models\User;
use function Laravel\Prompts\search;
// ...
return [
'user' => fn () => search(
label: 'Search for a user:',
placeholder: 'E.g. Taylor Otwell',
options: fn ($value) => strlen($value) > 0
? User::where('name', 'like', "%{$value}%")->pluck('name', 'id')
: []
),
];
Note
The comprehensive Laravel Prompts documentation includes additional information on the available prompts and their usage.
If you wish to prompt the user to select or enter options, you may include prompts in your command's handle
method. However, if you only wish to prompt the user when they have also been automatically prompted for missing arguments, then you may implement the afterPromptingForMissingArguments
method:
use Symfony\Component\Console\Input\InputInterface;
use Symfony\Component\Console\Output\OutputInterface;
use function Laravel\Prompts\confirm;
// ...
/**
* Perform actions after the user was prompted for missing arguments.
*
* @param \Symfony\Component\Console\Input\InputInterface $input
* @param \Symfony\Component\Console\Output\OutputInterface $output
* @return void
*/
protected function afterPromptingForMissingArguments(InputInterface $input, OutputInterface $output)
{
$input->setOption('queue', confirm(
label: 'Would you like to queue the mail?',
default: $this->option('queue')
));
}
Command I/O
Retrieving Input
While your command is executing, you will likely need to access the values for the arguments and options accepted by your command. To do so, you may use the argument
and option
methods. If an argument or option does not exist, null
will be returned:
/**
* Execute the console command.
*/
public function handle(): void
{
$userId = $this->argument('user');
}
If you need to retrieve all of the arguments as an array
, call the arguments
method:
$arguments = $this->arguments();
Options may be retrieved just as easily as arguments using the option
method. To retrieve all of the options as an array, call the options
method:
// Retrieve a specific option...
$queueName = $this->option('queue');
// Retrieve all options as an array...
$options = $this->options();
Prompting For Input
Note
Laravel Prompts is a PHP package for adding beautiful and user-friendly forms to your command-line applications, with browser-like features including placeholder text and validation.
In addition to displaying output, you may also ask the user to provide input during the execution of your command. The ask
method will prompt the user with the given question, accept their input, and then return the user's input back to your command:
/**
* Execute the console command.
*/
public function handle(): void
{
$name = $this->ask('What is your name?');
// ...
}
The secret
method is similar to ask
, but the user's input will not be visible to them as they type in the console. This method is useful when asking for sensitive information such as passwords:
$password = $this->secret('What is the password?');
Asking For Confirmation
If you need to ask the user for a simple "yes or no" confirmation, you may use the confirm
method. By default, this method will return false
. However, if the user enters y
or yes
in response to the prompt, the method will return true
.
if ($this->confirm('Do you wish to continue?')) {
// ...
}
If necessary, you may specify that the confirmation prompt should return true
by default by passing true
as the second argument to the confirm
method:
if ($this->confirm('Do you wish to continue?', true)) {
// ...
}
Auto-Completion
The anticipate
method can be used to provide auto-completion for possible choices. The user can still provide any answer, regardless of the auto-completion hints:
$name = $this->anticipate('What is your name?', ['Taylor', 'Dayle']);
Alternatively, you may pass a closure as the second argument to the anticipate
method. The closure will be called each time the user types an input character. The closure should accept a string parameter containing the user's input so far, and return an array of options for auto-completion:
$name = $this->anticipate('What is your address?', function (string $input) {
// Return auto-completion options...
});
Multiple Choice Questions
If you need to give the user a predefined set of choices when asking a question, you may use the choice
method. You may set the array index of the default value to be returned if no option is chosen by passing the index as the third argument to the method:
$name = $this->choice(
'What is your name?',
['Taylor', 'Dayle'],
$defaultIndex
);
In addition, the choice
method accepts optional fourth and fifth arguments for determining the maximum number of attempts to select a valid response and whether multiple selections are permitted:
$name = $this->choice(
'What is your name?',
['Taylor', 'Dayle'],
$defaultIndex,
$maxAttempts = null,
$allowMultipleSelections = false
);
Writing Output
To send output to the console, you may use the line
, info
, comment
, question
, warn
, and error
methods. Each of these methods will use appropriate ANSI colors for their purpose. For example, let's display some general information to the user. Typically, the info
method will display in the console as green colored text:
/**
* Execute the console command.
*/
public function handle(): void
{
// ...
$this->info('The command was successful!');
}
To display an error message, use the error
method. Error message text is typically displayed in red:
$this->error('Something went wrong!');
You may use the line
method to display plain, uncolored text:
$this->line('Display this on the screen');
You may use the newLine
method to display a blank line:
// Write a single blank line...
$this->newLine();
// Write three blank lines...
$this->newLine(3);
Tables
The table
method makes it easy to correctly format multiple rows / columns of data. All you need to do is provide the column names and the data for the table and Laravel will
automatically calculate the appropriate width and height of the table for you:
use App\Models\User;
$this->table(
['Name', 'Email'],
User::all(['name', 'email'])->toArray()
);
Progress Bars
For long running tasks, it can be helpful to show a progress bar that informs users how complete the task is. Using the withProgressBar
method, Laravel will display a progress bar and advance its progress for each iteration over a given iterable value:
use App\Models\User;
$users = $this->withProgressBar(User::all(), function (User $user) {
$this->performTask($user);
});
Sometimes, you may need more manual control over how a progress bar is advanced. First, define the total number of steps the process will iterate through. Then, advance the progress bar after processing each item:
$users = App\Models\User::all();
$bar = $this->output->createProgressBar(count($users));
$bar->start();
foreach ($users as $user) {
$this->performTask($user);
$bar->advance();
}
$bar->finish();
Note
For more advanced options, check out the Symfony Progress Bar component documentation.
Registering Commands
All of your console commands are registered within your application's App\Console\Kernel
class, which is your application's "console kernel". Within the commands
method of this class, you will see a call to the kernel's load
method. The load
method will scan the app/Console/Commands
directory and automatically register each command it contains with Artisan. You are even free to make additional calls to the load
method to scan other directories for Artisan commands:
/**
* Register the commands for the application.
*/
protected function commands(): void
{
$this->load(__DIR__.'/Commands');
$this->load(__DIR__.'/../Domain/Orders/Commands');
// ...
}
If necessary, you may manually register commands by adding the command's class name to a $commands
property within your App\Console\Kernel
class. If this property is not already defined on your kernel, you should define it manually. When Artisan boots, all the commands listed in this property will be resolved by the service container and registered with Artisan:
protected $commands = [
Commands\SendEmails::class
];
Programmatically Executing Commands
Sometimes you may wish to execute an Artisan command outside of the CLI. For example, you may wish to execute an Artisan command from a route or controller. You may use the call
method on the Artisan
facade to accomplish this. The call
method accepts either the command's signature name or class name as its first argument, and an array of command parameters as the second argument. The exit code will be returned:
use Illuminate\Support\Facades\Artisan;
Route::post('/user/{user}/mail', function (string $user) {
$exitCode = Artisan::call('mail:send', [
'user' => $user, '--queue' => 'default'
]);
// ...
});
Alternatively, you may pass the entire Artisan command to the call
method as a string:
Artisan::call('mail:send 1 --queue=default');
Passing Array Values
If your command defines an option that accepts an array, you may pass an array of values to that option:
use Illuminate\Support\Facades\Artisan;
Route::post('/mail', function () {
$exitCode = Artisan::call('mail:send', [
'--id' => [5, 13]
]);
});
Passing Boolean Values
If you need to specify the value of an option that does not accept string values, such as the --force
flag on the migrate:refresh
command, you should pass true
or false
as the value of the option:
$exitCode = Artisan::call('migrate:refresh', [
'--force' => true,
]);
Queueing Artisan Commands
Using the queue
method on the Artisan
facade, you may even queue Artisan commands so they are processed in the background by your queue workers. Before using this method, make sure you have configured your queue and are running a queue listener:
use Illuminate\Support\Facades\Artisan;
Route::post('/user/{user}/mail', function (string $user) {
Artisan::queue('mail:send', [
'user' => $user, '--queue' => 'default'
]);
// ...
});
Using the onConnection
and onQueue
methods, you may specify the connection or queue the Artisan command should be dispatched to:
Artisan::queue('mail:send', [
'user' => 1, '--queue' => 'default'
])->onConnection('redis')->onQueue('commands');
Calling Commands From Other Commands
Sometimes you may wish to call other commands from an existing Artisan command. You may do so using the call
method. This call
method accepts the command name and an array of command arguments / options:
/**
* Execute the console command.
*/
public function handle(): void
{
$this->call('mail:send', [
'user' => 1, '--queue' => 'default'
]);
// ...
}
If you would like to call another console command and suppress all of its output, you may use the callSilently
method. The callSilently
method has the same signature as the call
method:
$this->callSilently('mail:send', [
'user' => 1, '--queue' => 'default'
]);
Signal Handling
As you may know, operating systems allow signals to be sent to running processes. For example, the SIGTERM
signal is how operating systems ask a program to terminate. If you wish to listen for signals in your Artisan console commands and execute code when they occur, you may use the trap
method:
/**
* Execute the console command.
*/
public function handle(): void
{
$this->trap(SIGTERM, fn () => $this->shouldKeepRunning = false);
while ($this->shouldKeepRunning) {
// ...
}
}
To listen for multiple signals at once, you may provide an array of signals to the trap
method:
$this->trap([SIGTERM, SIGQUIT], function (int $signal) {
$this->shouldKeepRunning = false;
dump($signal); // SIGTERM / SIGQUIT
});
Stub Customization
The Artisan console's make
commands are used to create a variety of classes, such as controllers, jobs, migrations, and tests. These classes are generated using "stub" files that are populated with values based on your input. However, you may want to make small changes to files generated by Artisan. To accomplish this, you may use the stub:publish
command to publish the most common stubs to your application so that you can customize them:
php artisan stub:publish
The published stubs will be located within a stubs
directory in the root of your application. Any changes you make to these stubs will be reflected when you generate their corresponding classes using Artisan's make
commands.
Events
Artisan dispatches three events when running commands: Illuminate\Console\Events\ArtisanStarting
, Illuminate\Console\Events\CommandStarting
, and Illuminate\Console\Events\CommandFinished
. The ArtisanStarting
event is dispatched immediately when Artisan starts running. Next, the CommandStarting
event is dispatched immediately before a command runs. Finally, the CommandFinished
event is dispatched once a command finishes executing.
