# Implementations of `echo(1)`

[![This project is considered experimental](https://img.shields.io/badge/status-experimental-critical.svg)](https://benknoble.github.io/status/experimental/)

Based on [the Open Group POSIX specification](http://pubs.opengroup.org/onlinepubs/9699919799/).

## Why?

 - For fun

 - For sysadmins who need strictly compatible versions of echo

 - For someone who just "*wants echo to work, damnit*"

 - For reference

 - To demonstrate the difficulty of POSIX `echo(1)`

## Compiling

Build binaries with a POSIX-compatible `make(1)`. Individual targets are

provided for the implementations listed below.

**Supported Implementations**

 - POSIX

 - BSD

 - XSI

 - SystemV

## Bugs

 - No account for environment variables, e.g., `LANG` and `LC_*`

 - Limited error checking

 - No `make(1)` support for installation, out-of-source building, documentation

 - No tests

 - No documentation

If you find a bug, particularly in the implementation of the POSIX standard,

please file an issue.
