NetBSD 6.1.5 - man page for seq (netbsd section 1)

SEQ(1)				   BSD General Commands Manual				   SEQ(1)

NAME
     seq -- print sequences of numbers

SYNOPSIS
     seq [-w] [-f format] [-s string] [-t string] [first [incr]] last

DESCRIPTION
     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 %g.

     -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 notation as defined in ANSI X3.159-1989
		   (``ANSI C89'').  This option is useful when the default separator does not
		   contain a \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 non-zero if an error occurs.

EXAMPLES
	   # seq 1 3
	   1
	   2
	   3

	   # seq 3 1
	   3
	   2
	   1

	   # seq -w 0 .05 .1
	   0.00
	   0.05
	   0.10

HISTORY
     The seq command first appeared in Plan 9 from Bell Labs.  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.

BUGS
     The -w option does not handle the transition from pure floating point to exponent represen-
     tation very well.	The seq command is not bug for bug compatible with the Plan 9 from Bell
     Labs or GNU versions of seq.
