jot
utility is used to print out increasing,
decreasing, random, or redundant data (usually numbers) one per line.
The following options are available:
-b
word-c
-w
%c.-n
-p
precision-p
, the precision is the greater of the precisions
of begin and end. The
-p
option is overridden by whatever appears in a
printf(3) conversion
following -w
.-r
-s
string-w
wordThe 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. Any argument may be omitted, and will be considered as such if given as “-”. Any three of these arguments determines the fourth. If four are specified and the given and computed values of reps conflict, the lower value is used. If fewer than three are specified, defaults are assigned left to right, except for s, which assumes its default unless both begin and end are given.
Defaults for the four arguments are, respectively, 100, 1, 100, and 1, except that when random data are requested, s defaults to a seed depending upon the time of day. reps is expected to be an unsigned integer, and if given as zero is taken to be infinite. begin and end may be given as real numbers or as characters representing the corresponding value in ASCII. The last argument must be a real number.
Random numbers are obtained through
random(3). The name
jot
derives in part from
iota
, a function in APL.
