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
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 an NDB Cluster error code.
This option is deprecated in NDB 7.6.4 and later, where perror prints a warning if it is used, and subject to removal in a future NDB Cluster release series. 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.
