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

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.


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
