Octal, hexadecimal, exponential, ASCII, zero padded, and right-adjusted representations are possible by using the appropriate -.IR printf (3) +.Xr printf 3 conversion specification inside -.IR word , +.Ar word , in which case the data are inserted rather than appended. -.IP \fB\-c\fP +.It Fl c This is an abbreviation for \fB\-w %c\fP. -.IP \fB\-s\fP\ string +.It Fl s Ar string Print data separated by -.IR string . +.Ar string . Normally, newlines separate data. -.IP \fB\-n\fP +.It Fl n Do not print the final newline normally appended to the output. -.IP \fB\-p\fP\ precision +.It Fl p Ar precision Print only as many digits or characters of the data as indicated by the integer -.IR precision . +.Ar precision . In the absence of -.BR \-p , +.Fl p , the precision is the greater of the precisions of -.I begin +.Ar begin and -.IR end . +.Ar end . The -.B \-p +.Fl p option is overridden by whatever appears in a -.IR printf (3) +.Xr printf 3 conversion following -.BR \-w . -.PP +.Fl w . +.El +.Pp The last four arguments indicate, respectively, the number of data, the lower bound, the upper bound, and the step size or, for random data, the seed. While at least one of them must appear, any of the other three may be omitted, and will be considered as such if given as -.BR \- . +.Dq - . Any three of these arguments determines the fourth. If four are specified and the given and computed values of -.I reps +.Ar reps conflict, the lower value is used. If fewer than three are specified, defaults are assigned left to right, except for -.IR s , +.Ar s , which assumes its default unless both -.I begin +.Ar begin and -.I end +.Ar end are given. -.PP +.Pp Defaults for the four arguments are, respectively, 100, 1, 100, and 1, except that when random data are requested, -.I s +.Ar s defaults to a seed depending upon the time of day. -.I Reps +.Ar reps is expected to be an unsigned integer, and if given as zero is taken to be infinite. -.I Begin +.Ar begin and -.I end +.Ar end may be given as real numbers or as characters representing the corresponding value in ASCII. The last argument must be a real number. -.PP +.Pp Random numbers are obtained through -.IR random (3). +.Xr random 3 .
