commandline taskmgr / taskkiller for windows

[lepricaun]

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:

i hope you find it useful :)

(i've attached the program and source).

[edit]altered the code so that is compatible with (almost) all systems. (changed the "long code" to "unsigned long code")[/edit]

Very nice. I tested it and it seems to work just fine. Why would you want this though?

Very nice. I tested it and it seems to work just fine. Why would you want this though?

because there are tools like pskill and pslist, but if you wanted to kill a program:

run pslist --> get PID.

run pskill PID.

with my program it's just:

run prokill --> view and enter PID..

and why i wanted it for the commandline:

if you have it on a remote machine and you have a shell on that machine (presuming it is your own machine). then it would be pretty easy to administer the processes ran on that machine.
