Are you confusing system calls with core utilities?

maybei just want to know what happens when i press ls
Type
which ls
and it will tell you exactly which executable will be called.
Then look at the source for it.

CornedBee one last thing
how can i print the executable's name every time something is being executed?
I fail to see how that would be useful, but I suppose you'd have to look into the CRT implementation of the exec* family, track it down to the lowest common function and modify that to do what you want.

is there any possibility to know exactly what function i have to modify?
You don't mean something like this, by any chance?how can i print the executable's name every time something is being executed?
[edit] Never mind, I obviously didn't read the thread properly. [/edit]Code:#include <stdio.h> int main(int argc, char *argv[]) { printf("%s\n", argv[0]); return 0; }
[edit=2] Maybe this will be useful: http://www.raspberryginger.com/jbail...8c-source.html [/edit]

Could we please know exactly what you're trying to do, just to make sure we're talking about something that makes sense? I mean your ULTIMATE goal. Are you trying to monitor everything every process ever does?Originally Posted by squeezah
