Killing a process with a batch
Sandman
gratitude for those that reply, however helpful. :)
Okay, I'm new to batch programming and I'd like to write a batch file that
takes as a parameter a String (or maybe an int?) which represents a running
process and kills that process (similar to the End Process button in the
Windows Task Manager). I'm not sure if it matters, but it would need to
work on a NT/2000 machine.
Okay, now being new to batch programs and such, my problem is two fold:
1. how do I kill a process from the command line
2. how do I identify a process (is it a number or a string?). if it is a
number (which I believe intuitively it is), how would I aquire that number
from a command line given that I only had the string representation of the
process?
please be gentle,

This is actually handy from a scripting standpoint since it can be compiled into an ActiveX DLL and then just called with
object.KillProcess <processID>.
In fact, you can use it from VBA to kill process, so you can actually start a VBScript that starts VBA that calls this to kill something - no kill command or WMI needed.
I wouldn't recommend this for the casual user though. And no, I didn't just do this for the heck of it - I was working on it yesterday and figured this post would be a good excuse to modify it for easy scriptable use.
FWIW, I think your method is faster, Dean... :)))

for /f "tokens=1" %a in ('tlist ^| findstr /i "your process or program"') do echo kill %a /f
If this appears to do what you want, remove the word 'echo'. If you want to run it as a batch file,
then
for /f "tokens=1" %%a in ('tlist ^| findstr /i %1') do echo kill %%a /f
where '%1' is the window title or program name of the process.

"Eternally grateful" I could believe, "eternally gracious" simply remains to
be seen (and through multiple sets of eyes).
