<h1> The <tt>s6-seq</tt> program </h1>
<p>
s6-seq prints a sequence of numbers.
</p>
<h2> Interface </h2>
<pre>
s6-seq [ -w ] [ -s separator ] <em>limits</em>
</pre>
<ul>
<li> <em>limits</em> can be one, two or three arguments.
<ul>
<li> Three arguments are interpreted as <em>first</em>,
<em>increment</em> and <em>last</em>, in this order. </li>
<li> Two arguments are interpreted as <em>first</em> and
<em>last</em>, and <em>increment</em> defaults to 1. </li>
<li> One argument is interpreted as <em>last</em>, and
<em>first</em> and <em>increment</em> both default to 1. </li>
</ul> </li>
<li> s6-seq prints all unsigned integers from <em>first</em>
to <em>last</em> inclusive, with a step of <em>increment</em>,
with a newline after each integer.
It then exits 0. </li>
</ul>
<h2> Options </h2>
<ul>
<li> <tt>-w</tt> : fixed width. The numbers will all be printed
with the same width; smaller numbers will have leading <tt>0</tt>
characters. </li>
<li> <tt>-s</tt> <em>sep</em> : print <em>sep</em> after
each number. Default is a newline. If <em>sep</em>
is the empty string, a null character will be printed. </li>
</ul>
<h2> Notes </h2>
<p>
s6-seq is similar to the GNU <tt>seq</tt> program. However, it
does not handle negative numbers, floating point numbers or
printf-style formatting.
