windows: command line used to launch a program

Question

How can I find out the command line options a program was launched with under windows?

Answer 1

try: http://www.bleepingcomputer.com/tutorials/tutorial132.html

in short: use the Process Explorer utility created by Sysinternals (now owned by Microsoft; which is probably why vista and windows 7 now have a similar functionality already present in task manager)

Answer 2

Try running the .exe but with the /? flag.

Answer 3

On vista... You can

• go to the task manager
• Click View --> Select Columns
• Add the command line column.

To do this programatically, run "tasklist -v" to a file and then split up the file.

Answer 4

If you are trying to get the command line of another process programmatically you should probably read Why is there no supported way to get the command line of another process?:

Commenter Francisco Moraes wonders whether there is a supported way of getting the command line of another process. Although there are certainly unsupported ways of doing it or ways that work with the assistance of a debugger, there's nothing that is supported for programmatic access to another process's command line, at least nothing provided by the kernel. (The WMI folks have come up with Win32_Process.CommandLine. I have no idea how they get that. You'll have to ask them yourself.)

If you are trying to retrieve the command line of your own process you can use GetCommandLine.
