# Class yii\console\ExitCode

Inheritance | yii\console\ExitCode
Available since version | 2.0.13
Source Code | https://github.com/yiisoft/yii2/blob/master/framework/console/ExitCode.php

This class provides constants for defining console command exit codes.

The exit codes follow the codes defined in the FreeBSD sysexits(3) manual page.

These constants can be used in console controllers for example like this:

    public function actionIndex()
    {
        if (!$this->isAllowedToPerformAction()) {
             $this->stderr('Error: ' . ExitCode::getReason(ExitCode::NOPERM));
             return ExitCode::NOPERM;
        }

        // do something

        return ExitCode::OK;
    }

## Constants

Hide inherited constants

Constant | Value | Description | Defined By
--- | --- | --- | ---
CANTCREAT | 73 | A (user specified) output file cannot be created. | yii\console\ExitCode
CONFIG | 78 | Something was found in an unconfigured or misconfigured state. | yii\console\ExitCode
DATAERR | 65 | The input data was incorrect in some way. This should only be used for user's data and not system files. | yii\console\ExitCode
IOERR | 74 | An error occurred while doing I/O on some file. | yii\console\ExitCode
NOHOST | 68 | The host specified did not exist. This is used in mail addresses or network requests. | yii\console\ExitCode
NOINPUT | 66 | An input file (not a system file) did not exist or was not readable. This could also include errors like ``No message'' to a mailer (if it cared to catch it). | yii\console\ExitCode
NOPERM | 77 | You did not have sufficient permission to perform the operation. This is not intended for file system problems, which should use NOINPUT or CANTCREAT, but rather for higher level permissions. | yii\console\ExitCode
NOUSER | 67 | The user specified did not exist. This might be used for mail addresses or remote logins. | yii\console\ExitCode
OK | 0 | The command completed successfully. | yii\console\ExitCode
OSERR | 71 | An operating system error has been detected. This is intended to be used for such things as ``cannot fork'',` `cannot create pipe'', or the like. It includes things like getuid returning a user that does not exist in the passwd file. | yii\console\ExitCode
OSFILE | 72 | Some system file (e.g., /etc/passwd, /var/run/utx.active, etc.) does not exist, cannot be opened, or has some sort of error (e.g., syntax error). | yii\console\ExitCode
PROTOCOL | 76 | The remote system returned something that was ``not possible'' during a protocol exchange. | yii\console\ExitCode
SOFTWARE | 70 | An internal software error has been detected. This should be limited to non-operating system related errors as possible. | yii\console\ExitCode
TEMPFAIL | 75 | Temporary failure, indicating something that is not really an error. In sendmail, this means that a mailer (e.g.) could not create a connection, and the request should be reattempted later. | yii\console\ExitCode
UNAVAILABLE | 69 | A service is unavailable. This can occur if a support program or file does not exist. This can also be used as a catchall message when something you wanted to do does not work, but you do not know why. | yii\console\ExitCode
UNSPECIFIED_ERROR | 1 | The command exited with an error code that says nothing about the error. | yii\console\ExitCode
USAGE | 64 | The command was used incorrectly, e.g., with the wrong number of arguments, a bad flag, a bad syntax in a parameter, or whatever. | yii\console\ExitCode

getReason() public static method

Returns a short reason text for the given exit code.

This method uses $reasons to determine the reason for an exit code.

public static string getReason ( $exitCode )

Source code

                    public static function getReason($exitCode)
    {
        return isset(static::$reasons[$exitCode]) ? static::$reasons[$exitCode] : 'Unknown exit code';
    }
