In 96 lines, the ripple test pattern prints all 96 printable \fBASCII\fR characters in each position. The ripple test pattern was originally created to test printers. It is also useful for testing terminals, driving terminal ports, debugging, and performing tasks that require a quick supply of random data. .sp .LP This command is obsolete. .SH OPTIONS .sp .ne 2 .mk .na \fB\fIlength\fR\fR .ad .RS 10n .rt Specifies the length of the output line in characters. \fB79\fR characters is the default. .RE .sp .ne 2 .mk .na \fB\fIcount\fR\fR .ad .RS 10n .rt Specifies the number of output lines. \fB200\fR lines is the default. If \fIcount\fR is specified, \fIlength\fR must also be specified. .RE .SH EXIT STATUS .sp .LP The following exit values are returned: .sp .ne 2 .mk .na \fB\fB0\fR\fR .ad .RS 12n .rt Successful completion. .RE .sp .ne 2 .mk .na \fBnon-zero\fR .ad .RS 12n .rt An error occurred. .RE .SH SEE ALSO .sp .LP \fBattributes\fR(5)
