[SOLVED] LOGIN PROCESS dissecting

cedkhader · 05-19-2010, 05:54 AM

hi all,

i am looking for a detailed description of the login process for both root and normal user , also locally and remotely.

i read some sentences that the files .bashrc and bash_profile are needed for this process. But that was very concise.

MANY THANKS IN ADVANCE

It depends how deep you want to go. This would probably be a good start;

Which parts of it? The link given by redgoblin gives the framework, enough to tell you the components and thus allowing further research up to the ultimate of inspecting the source code. Your OP suggests an interest in what bash does at login but what you write does not suggest you have studied the man page which has a complete functional description; going deeper would require source code inspection.

It depends also if one logs in to a minimal system, or an X server. Are you building your own distro?

Specifically the bash man page available on line here. For bash-related man pages try the man -k bash command. For other online bash help try the info bash command. For man pages in general try the man man command.

This version of the man pages may be easier to search http://linux.die.net/man/

The INVOCATION section of the bash man page describes how files like .bashrc and .profile_bash are used under various bash startup scenarios.

There are many examples of customising them, for example here.

Linux' man pages and the Internet are great resources. Most of us use them frequently; it is effort well repaid to familiarise with them.
