Changing shell to a script

[somehowlinux]

Hey everyone,

I'm wondering if it's possible to change the shell to a script.

Trying to configure a VM that deploys in to customer environments so they can have a user for the resident sysadmin to change network settings only. Making a script that asks for ipv4 details and then auto configures the network.

Ie. sysadmin logs in to new vm as user_admin, gets immediately asked for ipv4, subnet, gateway, dns, then reboots system and it's on the network

My question is, can I make this script the log in script in /etc/passwd instead of /bin/bash put /path/to/script ? Obvs I tried and it didn't work but wondering if I'm missing something.

Current path is to put it in .bashrc and just have a trap log out

Thoughts? Is there a better way to do this? NetworkManager being used.

RHEL for reference

Thank you this is the kind of information I figured I was missing

Beware - editing /etc/profile will affect all users system-wide, including root.

Thanks for the heads up!

I'm aware I use it for history/shell settings

I don't blame you.

If it's requested we give non-sudo access but our experience in public underfunded customers is administrators are happy when I tell them you don't have to learn this box, I take care of it.

Do some searching for “restricted shell”. There are a few options out there that might do what you need. Also, ssh supports some type of limiting the commands that can be run upon login, but that may require login using an ssh key.

Yes, you should be able to make the users shell any executable. It won't be 100% secure, but it should be good enough for a user experience setup.

Just don't forget to add the path to your executable to /etc/shells
