hello,
I was going through a search engine & i came accross your e-mail id ,
well i want to know few things...like...
1) where can i find the executable file in Linux which acts similar to "autoexe.bat in windows environment" . like i need the complete path to that file that runs automatically.

2) Once we come to know about the file , how to break down inside the code , to know what other files this executable file must be running.
ok thanks , hoping for your prompt reply
bye
Sachin

Sachin,

There is no "autoexec.bat" file to speak of in Linux. There are different run-levels that correspond to different levels of access to the system.

http://seva.chicago.il.us/writings/a...alg-init.shtml

Each run level has different scripts that it will either run or make sure are not running. These scripts can be found in the /etc/rc.d directory. Each of these scripts can be editted in any text editor as long as you have permission to make changes to these files.

For example, /etc/rc5.d is the directory for run-level 5. In this directory you will find a list of symbolic links to /etc/rcd.d (going off of memory here, since I'm at work on a windows machine) which is where all of the scripts are located. A script for a firewall could be called simply "firewall". In the /etc/rc5.d directory, you would see a sybolic link called S10 firewall, which tells the system to start the firewall script in /etc/rcd.d. The 10 means that it would be the 10th (or so) item in the startup for that run-level, so it would have to start prior to #11 and so on.

If you want to change the way a system starts up at any run-level you can either modify the script, delete the symbolic link, comment it out in that run-level directory, or tell it to kill the process (K10 instead of S10).

That's it in a (wordy) nutshell.
