perror [options] errorcode ...
Описание (Description)
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.
