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 E, e, f, G, g, and % conver-sion conversion
                   sion 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     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

SEE ALSO
     jot(1), printf(1), printf(3)

HISTORY
     The seq command first appeared in Plan 9 from Bell Labs.  A seq command appeared in NetBSD 3.0, and
     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 utilities 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 compatible with the Plan 9 from Bell Labs or GNU versions of
     seq.
