Hallo all,
i have basic questions about linux.
1. Does so-called SCRIPT run in the course of initialization? Since they are not coded in normal computer language, how does it work with the operating system, say debian? After initialization, in case a script is altered, how could the modification be informed to the operating system?

2. When do I need to change envireroment variables? Where could I enter any variables, in the console? After typing the variables, where does they go?

3. In which directory are the temperory files of firefox per default saved?

4. Is there any kind of software geared for linux to making free call from computer to land phone?

Thanks in advance, win2s

1) I'm not 100% sure what you are asking for here. Yes there are multiple scripts run when a system is booted although you shouldn't need to do anything special after changing them for the system to be informed about them. The changed versions will just be run the next time the system boots.

2) They are stored in memory until the shell exits.

3) Check in ~/.mozilla

4) I don't know of any that will do it for free but check out Skype.

I attmept to let my X windows show some languages beside english, e.g. chinese, and luckily fond one howto article on it. One step for that purpose is to:
[quote]create a new file /etc/X11/Xsession.d/95xinput with the following content.

/usr/bin/scim -d
XMODIFIERS="@im=SCIM"
export XMODIFIERS
[quote]
I'd like to know which program will read/call this script and how does the program understand it since it is not coded in any common computer language?
I hope this post seems clearer.
regards, win2s

If I understand you correctly, you are looking at a shell script. Depending on what distribution you are running, you probably have the "bash" shell. The shell has it's own language (which you use everytime you enter a command in terminal). This same language is use for scripts.

The place to start is: "Bash Guide for Beginners", by Machtelt Garrels. it is at tldp.org If you are serious about learning scripting, i would also suggest "Classic Shell Scripting" from O'Reilly
