debian su – and su $PATH differences?
The two implementations are very similar but have some minor differences (and there might be more that was not yet noticed ofcourse), e.g.
su
Where did the “wheel” group get its name?
The wheel group on *nix computers typically refers to the group with some sort of root-like access. I’ve heard that on some *nixes it’s the group of users with the right to run su, but on Linux that seems to be anyone (although you need the root password, naturally). On Linux distributions I’ve used it seems to be the group that by default has the right to use sudo; there’s an entry in sudoers for them:
Why doesn’t “sudo su” in a shell script run the rest of the script as root?
A sample script can be as below:
su vs su – (on Debian): why is PATH the same?
I know what should be the difference between su and su -, but in my system (Debian) for example PATH is the same:
Why can’t we execute a list of commands as different user without sudo?
This question has been asked in a different way in other forums. But there has not been a decent explanation why you can’t do the below in bash.
What does ‘script /dev/null’ do?
Every time I log into a VM with root, su into a user account, and try to use screen it throws an error:
Running GUI application as another (non-root) user
Let’s say I have 2 user accounts user1 and user2. When I login as user1, and then switch to user2 using su, I can execute command-line programs, but GUI programs fail.
can’t ssh into remote host with root, password incorrect
I have a remote host,
previously I can ssh into it with root and password
Why is the ‘sudo’ password different than the ‘su root’ password
On my personal machine, I often type sudo in front of certain commands in order to accomplish administrative tasks. I had hoped to avoid doing this throughout the day, by typing su root and providing the same password I usually do for sudo. However, the two passwords are not the same(I don’t know how to log in to su root). Is running a command with sudo different than logging in with su root and running the same command?
When do su and sudo use different passwords?
I am able to run anything using sudo; my password is accepted. But whenever I try to do su from a shell, it fails with:
