perror(1) MySQL Database System perror(1)
NAME
perror - display MySQL error message information
SYNOPSIS
perror [options] errorcode ...
DESCRIPTION
perror displays the error message for MySQL or operating system error
codes. Invoke perror like this:
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.
$> 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:
$> 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.
o --help, --info, -I, -? Display a help message and exit.
o --silent, -s Silent mode. Print only the error message.
o --verbose, -v Verbose mode. Print error code and message. This is the
default behavior.
o --version, -V Display version information and exit.
