typic newbie questions
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
