Free macro commands software for windows

Mac-Ro-Knife is a small and reliable Java-based software that is used for running simple command line based macros on multiple hosts running secure shell.
Usage should be somewhat self explanatory, but writing macros may not. Because of this, a sample Mac-Ro-Knife or .mrk file is available that contains several macros with explanations of the macro features/syntax.
A basic usage example would be that you wanted to change your password on
several *NIX based systems automatically, and that currently you have the same user name and password and every system that you desire to change (private keys are planned future feature).
You would create a simple macro like so:
passwd
%newpassword%
%newpassword%
You would then select which hosts to run that macro on. Once the hosts and
macros have been selected, you hit the Run button, and would be prompted for a login username and password along with any variables that were defined in the macros that are to be run. In this case, newpassword.
The application would then begin sequentially running through all the enabled hosts and run the macro command set in their specified macro (multi-threading is being considered for vastly increased performance).
System requirements:
- Java JRE

Enhancements:
- Multithreaded simultaneous macro running
- Generic interface for macro meta commands
- Control character macro meta commands
- If-Then-Else macro meta command
- Linewait macro meta command
- Loop macro meta command
- Login user information macro meta command
