<h1> s6-portable-utils </h1>
<h2> What is it ? </h2>
<p>
s6-portable-utils is a set of tiny general Unix utilities, often
performing well-known tasks such as <em>cut</em> and <em>grep</em>,
but optimized for simplicity and small size. They were designed
for embedded systems and other constrained environments, but they
work everywhere.
</p>
<p>
Other set of small utilities are usually system-specific; for
instance, the (otherwise good)
<a href="http://busybox.net/">BusyBox</a> project only works on Linux.
</p>
<p>
Some of s6-portable-utils' programs are a conformant implementation
of a POSIX utility as determined by the
<a href="http://pubs.opengroup.org/onlinepubs/9699919799/nfindex.html">Single
Unix Specification, version 4</a>; the relevant documentation pages mentions
this.
However, none of the s6-portable-utils programs supports internationalization.
</p>
<p>
It is now an explicit non-goal of s6-portable-utils to duplicate the work of
existing projects that aim to provide a lightweight implementation of
standard commands.
No more rewriting of standard commands will occur in s6-portable-utils;
the package is now used to host specific utilities such as
<a href="s6-uniquename.html"><tt>s6-uniquename</tt></a>.
