LUU (Lawson Unix Utility)

Haven't tried it, but it's not supported. To answer your question, requires JDK, Perl and SUA (or cygwin in latest version of LUU). What are you trying to accomplish?

I want to write shell script to stop/start windows PIDs, such as: ps -ef:grep iexplore. If exists, kill -9 $pid and so on. I have Cygwin, don't know how cd C drive

Are you talking about on the individual desktops? Or from the server? If desktop there are a variety of other batch commands and/or scripts that you could use without having to install something like LUU - but, yes, its not unix-like commands.

don't use shell script -- use powershell--it's part of Windows...
kill -processname iexplore

I have power shell too, but sure if commands like: if, else, while work as ksh

cygwin does the trick for me, such as:

ps -W | grep -v grep |grep iexplore

if exists, exit, else cygstart iexplore.exe

thanks for pointing out. i only cygwin for xwindows for the last 10 years.
