How do you execute command line tools without using batch file in Inno Setup

Question

I now understand that "Inno Setup can execute command line tools for you without utilizing batch file." (Can Inno Setup install set up a Windows security group?) It makes sense that it would be able to do that. From my web searches into Inno Setup thus far, I can not find an starting place to understand how to do this. A complete answer may not be necessary, if I just had some further hint as to what to look for, that would probably be good enough.

Answer 1

It was meant that you don't need to create and execute a batch script (with a single command), nor execute the tool through the command prompt (like shown below):

Exec('cmd.exe', '/c "net localgroup ..."', '', SW_SHOW, ewWaitUntilTerminated, Result);

But you directly execute the tool instead:

Exec('net.exe', 'localgroup ...', '', SW_SHOW, ewWaitUntilTerminated, Result);

The same applies to the [Run] section:

[Run]
Filename: "{cmd}"; Parameters: "/c ""net localgroup ..."""

Better would be this:

[Run]
Filename: "net.exe"; Parameters: "localgroup ..."
