seq -- print sequences of numbers
seq [-w] [-f format] [-s string] [-t string] [first [incr]] last
The 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 format Use a printf(3) style format to print each number. Only
the A, 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
-s string Use string to separate numbers. The string can contain
character escape sequences in backslash notation as defined
in ANSI X3.159-1989 (``ANSI C89''). The default is \n.
-t string Use string to terminate sequence of numbers. The string
can contain character escape sequences in backslash nota-
tion as defined in ANSI X3.159-1989 (``ANSI C89''). The
default is \n.
-w Equalize the widths of all numbers by padding with zeros as
necessary. This option has no effect with the -f option.
If any sequence numbers will be printed in exponential
notation, the default conversion is changed to %e.
The seq utility exits 0 on success, and >0 if an error occurs.
# seq 1 3
# seq 3 1
# seq -w 0 .05 .1

The 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.
The -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.
