seq(1) User Commands seq(1)
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 become 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 defaults to %.PRECf if
FIRST, INCREMENT, and LAST are all fixed point decimal numbers with
maximum precision PREC, and to %g otherwise.
