These tables list features of different AWK versions on different operating systems.
If you want to help to complete this list, download the script testawk.sh run it on your system (sh testawk.sh), and mail the results to heiner.steven@shelldorado.com.
The table caption lists a short name for the operating system, e.g. "Solaris 2.8", followed by the shortened output of "uname -a", e.g. "SunOS 5.8 sun4u sparc SUNW,Ultra-5_10".
