Hi guys,

I am new to linux and despite of searching alot on google still confused about following basic concepts,

1. What is the difference between /etc/.profile and ~/bash_profile? If i make changes in /etc/profile, it will be implemented system wide for all users and all shells but changes in ~/bash_profile will be specific to that specific user only, is this correct?

2. If changes are made in ~/bash_profile of a user but default shell of user is not bash then nothing will happen, correct? In other words changes in ~/bash_profile will only affect bash shell of that specific user.

3. Suppose i have a script (/tmp/abc) and i want this script to run each time a specific user login, should i add following line in his ~/bash_profile,

sh /tmp/abc

but again if the default shell of that user is not bash, then nothin will happen, right?

4. For same script (/tmp/abc), i want it to run each time any user login, should i add following line in /etc/profile,

sh /tmp/abc

is this correct?

5. What is the difference between ~/.bashrc and ~/.bash_profile?

6. For achieving point 4, can i proceed like this. Add this script to rc(x).d directory of default runlevel?

I will be really thankful to anyone who can help me with these points and this thread will certainly help alot of newbies like me.

Thanks
