Thread: command line taskmgr / taskkiller for windows

hi all,

a couple of months ago i was searching really hard for a command line version of the windows taskmgr, but i wasn't able to find one

so today i decided to write one myself, my brain was extremely overheating during the coding :lol:, but i have finished it just a few minutes ago

since no one could give me a link or name from a similar program, i thought that it might come in handy for some people, so i decided to publish it under the GPL, so here is the source:

Code:
