(errno: #) message \&.\&.\&. (Errcode: #) .fi .if n \{\ .RE .\} .PP You can find out what the error code means by examining the documentation for your system or by using the \fBperror\fR utility\&. .PP \fBperror\fR prints a description for a system error code or for a storage engine (table handler) error code\&. .PP Invoke \fBperror\fR like this: .sp .if n \{\ .RS 4 .\} .nf shell> \fBperror [\fR\fB\fIoptions\fR\fR\fB] \fR\fB\fIerrorcode\fR\fR\fB \&.\&.\&.\fR .fi .if n \{\ .RE .\} .PP Example: .sp .if n \{\ .RS 4 .\} .nf shell> \fBperror 13 64\fR OS error code 13: Permission denied OS error code 64: Machine is not on the network .fi .if n \{\ .RE .\} .PP 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\&. .PP \fBperror\fR supports the following options\&. .sp .RS 4 .ie n \{\ \h'-04'\(bu\h'+03'\c .\} .el \{\ .sp -1 .IP \(bu 2.3 .\} .\" perror: help option .\" help option: perror \fB\-\-help\fR, \fB\-\-info\fR, \fB\-I\fR, \fB\-?\fR .sp Display a help message and exit\&. .RE .sp .RS 4 .ie n \{\ \h'-04'\(bu\h'+03'\c .\} .el \{\ .sp -1 .IP \(bu 2.3 .\} .\" perror: silent option .\" silent option: perror \fB\-\-silent\fR, \fB\-s\fR .sp Silent mode\&.
