Hello,

I'm in a position now where we all use sudo to login as a particular
user to run our daily batch jobs. The problem is that we all want to
set things up slightly differently (Editors, logging dir's, etc).

What I'm having a hard time with is identifying who sudo'd in. If I
could find this, then I could run some checks in .bashrc to setup our
environments correctly.

I thought that maybe I could do something with the PID and tie it to
the sudo process... but I think that is stretching it a bit.

Any thoughts?

Thanks

Matt

Unfortunately, not on my system. But it is what I was looking for.

Thanks

I may have found my problem, but I'm not sure of how to solve it.
When I sudo, I sudo as another login shell (ie sudo su - jack)

So my thought is that the $SUDO_USER is getting set to nothing (or not
set at all) and hence i don't get the benefit.

So... is there any way to get the value of $SUDO_USER from a login
shell? I've tried echo $SUDO_USER from my .profile, and I get
unbound variable message, so my guess is that I'm SOL.


Any thoughts, comments or jokes?

Try 'who am i' - with the spaces.

ms:/u/purdym>sudo /usr/bin/su - sybase
sybase@ms:/home/sybase>whoami
sybase
sybase@ms:/home/sybase>who am i

Thank you, Miles.

Exactly what I needed.

If you have the power to edit the sudoers file, make it so that you can
sudo as jack without "sudo su -". "sudo -i" runs as a login shell.

Not with all versions of sudo.

$ sudo -i
sudo: Illegal option -i
usage: sudo -V | -h | -L | -l | -v | -k | -K | [-H] [-S] [-b]
[-p prompt] [-u username/#uid] [-c class] -s | <command>
