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 ... Example: 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 Note that 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. o --help, --info, -I, -? Display a help message and exit. o --ndb Print the error message for a MySQL Cluster error code. o --silent, -s Silent mode. Print only the error message. o --verbose, -v Verbose mode. Print error code and message. This is the default behavior. o --version, -V Display version information and exit.
