.SH DESCRIPTION
|
| 15 |
|
|
.I Cnt
|
| 16 |
|
|
counts from 0 to N-1, producing N lines of output.
|
| 17 |
|
|
If multiple arguments are given,
|
| 18 |
|
|
.I cnt
|
| 19 |
|
|
produces a nested array of values where the final counter
|
| 20 |
|
|
rotates fastest through its range.

The
|
| 22 |
|
|
.I \-s
|
| 23 |
|
|
option shuffles the output lines, giving a different random
|
| 24 |
|
|
order on each invocation.
|

.I Cnt
|
| 26 |
|
|
is most useful in conjunction with
|
| 27 |
|
|
.I rcalc(1)
|
| 28 |
|
|
to produce array values.
|

|
|
.SH EXAMPLE
|
| 30 |
|
|
To create a 3 by 5 array:
|
| 31 |
|
|
.IP "" .2i
|
| 32 |
|
|
cnt 3 5
|
| 33 |
greg |
1.5 |
.PP
|
| 34 |
|
|
To generate a random shuffle of indices 0 through 51:
|
| 35 |
|
|
.IP "" .2i
|
| 36 |
|
|
cnt -s 52
|
| 37 |
|
|
.PP
|
| 38 |
|
|
Similar shuffling broken down by suit:
|
| 39 |
|
|
.IP "" .2i
|
