perror − explain error codes
|
perror [options] errorcode ... |
For most system errors, MariaDB 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
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.
• −−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.
