seq - print sequences of numbers

       Option  -w  always  surveys  every  value  in advance.  Thus seq -w 1000000000 is a painful way to get an
       `infinite' sequence.

                                                                                                     SEQ(1plan9)

Seq  prints  a  sequence of numbers, one per line, from first (default 1) to as near last as possible, in
       increments of incr (default 1).  The loop is:

         for(val = min; val <= max; val += incr) print val;

       The numbers are interpreted as floating point.

       Normally integer values are printed as decimal integers.  The options are

       -fformat   Use the print(3)-style formatprint for printing each (floating point) number.  The default is

       -w         Equalize the widths of all numbers by padding with leading zeros as necessary.  Not  effective
                  with option -f, nor with numbers in exponential notation.

       seq 0 .05 .1
              Print 00.050.1 (on separate lines).

       seq -w 0 .05 .1
              Print 0.000.050.10.
