|PERROR(1)||MySQL Database System||PERROR(1)|
perror [options] errorcode ...
shell> perror [options] errorcode ...
perror attempts to be flexible in understanding its arguments. For example, for the ER_WRONG_VALUE_FOR_VAR error, perror understands any of these arguments: 1231, 001231, MY-1231, or MY-001231, or ER_WRONG_VALUE_FOR_VAR.
shell> perror 1231 MySQL error code MY-001231 (ER_WRONG_VALUE_FOR_VAR): Variable '%-.64s' can't be set to the value of '%-.200s'
If an error number is in the range where MySQL and operating system errors overlap, perror displays both error messages:
shell> perror 1 13 OS error code 1: Operation not permitted MySQL error code MY-000001: Can't create/write to file '%s' (OS errno %d - %s) OS error code 13: Permission denied MySQL error code MY-000013: Can't get stat of '%s' (OS errno %d - %s)
To obtain the error message for a MySQL Cluster error code, use the ndb_perror utility.
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.
Display a help message and exit.
Print the error message for a MySQL Cluster error code.
This option was removed in MySQL 8.0.13. Use the ndb_perror utility instead.
Silent mode. Print only the error message.
Verbose mode. Print error code and message. This is the default behavior.
Display version information and exit.
