PERROR

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.

• −−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.
