seq —
| seq | [ -w] [-fformat] [-sstring] [-tstring] [first
      [incr]] last | 
seq utility prints a sequence of numbers, one per
  line (default), from first (default 1), to near
  last as possible, in increments of
  incr (default 1). When first is
  larger than last, the default incr
  is -1.
All numbers are interpreted as floating point.
Normally integer values are printed as decimal integers.
The seq utility accepts the following
    options:
-f
    formatA, a,
      E, e,
      F, f,
      G, g, and
      % conversion characters are valid, along with any
      optional flags and an optional numeric mimimum field width or precision.
      The format can contain character escape sequences in
      backslash notation as defined in ANSI X3.159-1989
      (“ANSI C89”). The default is
      %g.-s
    string\n.-t
    string\n.-w-f option. If
      any sequence numbers will be printed in exponential notation, the default
      conversion is changed to %e.seq utility exits 0 on success,
  and >0 if an error occurs.

seq command first appeared in Version 8
  AT&T UNIX. A seq command
  appeared in NetBSD 3.0. This command was based on the
  command of the same name in Plan 9 from Bell Labs and the GNU core utilities.
  The GNU seq command first appeared in the 1.13 shell
  utilities release.
-w option does not handle the transition from pure
  floating point to exponent representation very well. The
  seq command is not bug for bug compatible with other
  implementations.
