Neutralize user's environment

bengoavs · 12-25-2007, 02:11 AM

We have some automation tool written in bash. The tool is independent and doesn't require settings of environment before running it. But, it seems that certain envs mess up with it and make it fail.

How can a user's environment (.bashrc in that case) can be neutralized?

Thanks!

Whenever you make a user, the .bashrc and .bash_profile should be the same unless users are modifying it themselves. To make environment variables consistent for all users, look at /etc/profile.

I'm not sure if it's possible to wipe all environment variables, or that you would wan to. But you can unset specific variables with a line like:

unset varname

I'm aware of that. Can't force a golbal environment. Just want to neutralize it

Like what 'usernamenumber' mentioned above? Give us an example so maybe we can provide you some better ideas on how to tackle this problem.

Let's say my tool uses some modules at /mod (everything is in clearcase, but just for the simple demonstration).

A certain user has a .bashrc with LD_LIBRARY_PATH=/whatever

It runs over the script env, and causes errors

Ok, then why not just export all the env variables you need within your automated script?
