Questions tagged as ['sudo']

I am trying to understand why this simple command does not work.

sudo echo "a" >> /var/log/a.txt

It returns.

-bash: /var/log/a.txt: Permission denied

But I do have permission to rw by other means, for example editing it with nano

sudo nano /var/log/a.txt

or by being logged into root

sudo su -
echo "a" >> /var/log/a.txt

How can I "apply sudo" to >>?

I would like to grant permission to a group of users to run a systemctl service that only sudo users can executable.

I put the etc/sudoers (visudo) command below and it works:

%group_a ALL=(root) NOPASSWD: /bin/systemctl enable --now app_xxx@user_01

But would it be possible to pass the $USER environment variable as below?

So,

I noticed that on manjaro, if there is only one user, typing reboot without sudo, will just fail and ask for the sudo password, whereas on ubuntu server, typing this doesn't ask for the sudo password and successfully reboot the system. My question is how can I make it so that when I type reboot/shutdown/halt, ubuntu always asks for the sudo password even if there is only one user currently logge ...

There are a few suggestions out there with clues about how this might be achieved. It seems to me that the restart command of Elasticsearch shouldn't need root privileges, at least in my use case.

Basically, in case the ES service stops I don't want the user of the program to have the responsibility of restarting it, and the program, after detecting that the service is inactive/dead for some reason, sho ...

I have a laptop that has a really complicated password, however I don't want to keep typing this in during procedurs that requires sudo. Can I have another more simple sudo password after logging in for routine stuff? Is this a security risk? thanks.

I have installed few programs as root (lets say program A, B and C). In order to run them, it will require root access. I understand that by adding those users or the user group to sudoers list, it will allow access to those specific programs.

I would like to limit access to programs A, B and C only and not give full sudo access to general users. How can I achieve it?

I can connect to my server with ssh and launch graphic applications (like sublime). When I want to modify a system file, I use a command like sudo subl /etc/fstab

to install packages, it works fine and installs all packages. after I run

, I get so many nonsense typescript errors like can't find react router type. Why is that? btw if I run

sudo yarn build

it works fine.

As the title says. Interesting behavior. I just switched over to nologin on root user for security, after adding my user to root and sudo groups. I added a longer sudo timeout as described in the link below. So I should be able to use usermod without adding sudo because root owns /etc/passwd and user is part of the root group..no?

I'm updating to Ubuntu 21.04 and apt wants to swap out my sudoers file with one where #include is replaced by @include. Is the old syntax deprecated? It's not something I seem to be able to google.

When I run

sudo apt-get remove nordvpn 

and when I try

or

find -name "*nord*"

nothing shows up These commands are indicating that I don't have nord installed on my system, However every time I run

sudo apt-get update 

It will try to connect to nordvpn

I can't change passwd because it is read only.

I configured hibernate as described here and installed Simpler Off Menu gnome-shell-extension with the help of this instruction.
