The `s6-seq` program

s6-seq prints a sequence of numbers.

Interface

     s6-seq [ -w ] [ -s separator ] limits

limits can be one, two or three arguments.
- Three arguments are interpreted as first, increment and last, in this order.
- Two arguments are interpreted as first and last, and increment defaults to 1.
- One argument is interpreted as last, and first and increment both default to 1.
s6-seq prints all unsigned integers from first to last inclusive, with a step of increment, with a newline after each integer. It then exits 0.

-w : fixed width. The numbers will all be printed with the same width; smaller numbers will have leading 0 characters.
-s sep : print sep after each number. Default is a newline. If sep is the empty string, a null character will be printed.

s6-seq is similar to the GNU seq program. However, it does not handle negative numbers, floating point numbers or printf-style formatting.
