Questions to FAQ about TCL

[Sashank999]

Whenever you open a new aterm window, it loads TCL Default shell - "ash".

Type in :

Code: [Select]

bashto get back to bash shell so that you get those environment variables back.

Do you mean that the system uses .arshrc files or.bashrc depending on the shell being used?

[andyj]

Every shell uses it's own rc file. This is the case for all Linux systems. However they should all use .profile and /etc/profile. You will be better off to use these instead. If you want to use bash instead of busybox ash you will need to modify /etc/passwd to set the default shell.

@andyj
ok.I get it.

I was curious how TCL managed to restore the system to its original state when it was turned off, and how it loaded the entire system into RAM when it was turned on. What is the technical term for these techniques? Is this done by storing all the system files in the Initrd file? Is there any reference or technical literature?

Hi Trump
These diagrams should help:

Mount mode:

Copy mode:

I confused about 30 min looking at that diagram figuring where to start (I saw it in the TCL page an eternity ago). Start from "Files in CD/HDD/USB".

 I don't know the technical literature terms used but what I know is that the TCL uses the same method of "Live Linux CDs". Live Linux CDs load their Linux OS into RAM and then do our work. In the same way, TCL does the same thing. It has all of its required files in the kernel and initrd. And on what I researched, it is called tmpfs.

@Sashank999 @Rich
I'm confused...

[Sashank999]

tmpfs means loading full OS files into RAM. And its full description and info is in Wikipedia link above.

The diagrams Rich said are flowcharts that contain whole info about the TCL loading on boot up into RAM. Start at "Files in CD/HDD/USB" in those diagrams to get info about files you need to run TCL.

Q12: The following error messages appear every time you boot. How can you eliminate them? Or just turn it on and not show all the information?
