Re: Bash Session

[Kurian Thayil <kurianmthayil@gmail.com>]

Hi Andrew,

I guess parsing /etc/passwd and /etc/shadow file and sending an email notification is a good one. But don't you think, that .bashrc concept and inclusion of tasks in it will be quite confusing and complicated for a beginner? I will have to explain about login and non-login shell, startup scripts which will make them more confusing. Don't you think?

Regards,

Kurian Thayil.

 I'd focus on a variety of contexts where scripting is
handy -- .bashrc and cron leap to mind.

 What can you do in your .bashrc file?  Set environment
variables, extend/modify your path, detect the local
architecture, and so forth.

 What's useful in cron?  Parse /etc/passwd or /etc/shadow
and send yourself an e-mail expiry notice, maybe.

 Automatic creation and testing of back-ups, maybe.

 Simple scripts, and in an environment (especially in .bashrc)
where other tools just aren't as good.
