PERROR(1)

NAME
perror - display MySQL error message information

SYNOPSIS

perror [options] errorcode ...

DESCRIPTION

perror displays the error message for MySQL or operating system error codes. Invoke perror like this:

    perror [options] errorcode ...

perror attempts to be flexible in understanding its arguments. For example, for the ER_WRONG_VALUE_FOR_VAR error, perror understands any of these arguments: 1231, 001231, MY-1231, or MY-001231, or ER_WRONG_VALUE_FOR_VAR.

    $> perror 1231
    MySQL error code MY-001231 (ER_WRONG_VALUE_FOR_VAR): Variable '%-.64s'
    can't be set to the value of '%-.200s'

If an error number is in the range where MySQL and operating system errors overlap, perror displays both error messages:

    $> perror 1 13
    OS error code   1:  Operation not permitted
    MySQL error code MY-000001: Can't create/write to file '%s' (OS errno %d - %s)
    OS error code  13:  Permission denied
    MySQL error code MY-000013: Can't get stat of '%s' (OS errno %d - %s)

To obtain the error message for a MySQL Cluster error code, use the ndb_perror utility.

The meaning of system error messages may be dependent on your operating system. A given error code may mean different things on different operating systems.

perror supports the following options.

    • --help, --info, -I, -? Display a help message and exit.

    • --ndb Print the error message for a MySQL Cluster error code.

    This option was removed in MySQL 8.0.13. Use the ndb_perror utility instead.

    • --silent, -s Silent mode. Print only the error message.

    • --verbose, -v Verbose mode. Print error code and message. This is the default behavior.

    • --version, -V Display version information and exit.
