SEQ(1)			     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, --format 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 minimum 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, --separator 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, --terminator string
	     Use string to terminate sequence of numbers.  The string  can  con-
	     tain character escape sequences in backslash notation as defined in
	     ANSI  X3.159-1989 ("ANSI C89").  This option is useful when the de-
	     fault separator does not contain a \n.

     -w, --fixed-width
	     Equalize the widths of all numbers by padding with zeros as  neces-
	     sary.   This  option  has no effect with the -f option.  If any se-
	     quence numbers will be printed in exponential notation, the default
	     conversion is changed to %e.

EXIT STATUS
     The seq utility exits 0 on success, and >0 if an error occurs.

EXAMPLES
     Generate a sequence from 1 to 3 (included) with a default increment of 1:

	   # seq 1 3
	   1
	   2
	   3

     Generate a sequence from 3 to 1 (included) with a default increment of -1:

	   # seq 3 1
	   3
	   2
	   1

     Generate a sequence from 0 to 0.1 (included) with an increment of 0.05  and
     padding with leading zeroes.

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

     Generate a sequence from 1 to 3 (included) with a default increment of 1, a
     custom separator string and a custom terminator:

	   # seq -s "-->" -t "[end of list]\n" 1 3
	   1-->2-->3-->[end of list]

     Generate  a  sequence  from  1 to 2 (included) with an increment of 0.2 and
     print the results	with  two  digits  after  the  decimal	point  (using  a
     printf(3) style format):

	   # seq -f %.2f 1 0.2 2
	   1.00
	   1.20
	   1.40
	   1.60
	   1.80
	   2.00

HISTORY
     The  seq  command first appeared in Version 8 AT&T UNIX.  A seq command ap-
     peared in NetBSD 3.0, and was ported to  FreeBSD  9.0.   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 util-
     ities release.

BUGS
     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 com-
     patible with other implementations.
