K93 Unix
|
The K93_Unix project is in the process of moving to SourceForge at the following URL:
The latest version of these scripts is now on sourceforge now and will no longer be maintained here.
Script development policies, guidelines, standards, and procedures are being developed, and as soon as they are stable, those wanting to participate and/or contribute code to this project will be welcome to do so.
The shunix project contains numerous Korn Shell 93 shell scripts that emulate many of the standard unix utilities. These Korn Shell 93 shell scripts are designed to be used as part of a function library or as command line utilities. The purpose of these scripts is to provide the script programmer with the ability to easily incorporate unix command utilities into their shell scripts. This has the added benefit of allowing the shell programmer to easily change the behavior of the utilities.
These scripts represent selected Unix utilities and selected options for each utilities. Additional utilities and options will be periodically added.
You are free to download and evaluate these scripts. If you choose to continue to use these scripts in a commercial environment, you will be required to obtain a license for this purpose. Please contact Mt Xia for licensing details.
