Exercise with ps

Exercise with ps

Chrome from GUI:

1. Launch Chrome from the Linux GUI.
2. In command-line, type ps
3. Chrome is not in the list of processes. Why not?
4. How do you make a list of processes that includes Chrome?

Chrome from command-line:

1. Launch Chrome from command-line:

    google-chrome &  

2. ps now shows Chrome
3. It actually shows a program called "chrome" running, not "google-chrome".
4. So what is google-chrome? Type:

    which google-chrome 

5. The program is a shell script. Look inside it (how?) to find where it leads. Last time I looked:
   • Code leads into a shell function.
   • Then back to the command-line. Maybe follow a trail of shortcuts.
   • Into another shell script.
   • And then finally a reference to the real "chrome" program, which is huge, and you can see on the command-line.
