NAME
seq - print a sequence of numbers
SYNOPSIS
seq [OPTION]... LAST
seq [OPTION]... FIRST LAST
seq [OPTION]... FIRST INCREMENT LAST
DESCRIPTION
Print numbers from FIRST to LAST, in steps of INCREMENT.
Mandatory arguments to long options are mandatory for short options too.
-f, --format=FORMAT
use printf style floating-point FORMAT
-s, --separator=STRING
use STRING to separate numbers (default: \n)
-w, --equal-width
equalize width by padding with leading zeroes
--help
display this help and exit
--version
output version information and exit
If FIRST or INCREMENT is omitted, it defaults to 1. That is, an omitted
INCREMENT defaults to 1 even when LAST is smaller than FIRST. The sequence
of numbers ends when the sum of the current number and INCREMENT would be-
come greater than LAST. FIRST, INCREMENT, and LAST are interpreted as
floating point values. INCREMENT is usually positive if FIRST is smaller
than LAST, and INCREMENT is usually negative if FIRST is greater than LAST.
INCREMENT must not be 0; none of FIRST, INCREMENT and LAST may be NaN.
FORMAT must be suitable for printing one argument of type 'double'; it de-
faults to %.PRECf if FIRST, INCREMENT, and LAST are all fixed point decimal
numbers with maximum precision PREC, and to %g otherwise.
