       perror - explain error codes

       perror [options] errorcode ...

       For most system errors, MySQL displays, in addition to an internal text message, the system error code in one
       of the following styles:

           message ... (errno: #)
           message ... (Errcode: #)

       You can find out what the error code means by examining the documentation for your system or by using the
       perror utility.

       perror prints a description for a system error code or for a storage engine (table handler) error code.

       Invoke perror like this:

           shell> perror [options] errorcode ...


           shell> perror 13 64
           OS error code  13:  Permission denied
           OS error code  64:  Machine is not on the network

       To obtain the error message for a MySQL Cluster error code, invoke perror with the --ndb option:

           shell> perror --ndb errorcode

       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.

       ?   --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.
