s6-portable-utils

What is it ?

s6-portable-utils is a set of tiny general Unix utilities, often performing well-known tasks such as cut and grep, but optimized for simplicity and small size. They were designed for embedded systems and other constrained environments, but they work everywhere.

Other set of small utilities are usually system-specific; for instance, the (otherwise excellent) BusyBox project only works on Linux.

Some of s6-portable-utils' programs are a conformant implementation of a POSIX utility as determined by the Single Unix Specification, version 4; the relevant documentation pages mentions this. However, none of the s6-portable-utils programs supports internationalization.
