General :: Execute Root Command Without Sudo?
Jan 24, 2010
On my ubuntu I have a command pm-suspend, which puts the computer to sleep. It has to be run with sudo. Since it is inconvenient to be forced to type the password every time I want my computer to sleep, I thought maybe there's a way around it. Naively I thought that if I'd create a script as root, that invokes pm-suspend, and then let anyone execute that script, I could run that script as my own user and then that script would be considered run by root and hence be allowed to run pm-suspend. Obviously that didn't work. The root-check procedure in pm-suspend still found out that the original executor was someone different from root.
Still I think something similar (although slightly more elaborate) should work.I'm thinking about the process that allows the user to mount hard drives for example. Normally root is required, but it is somehow bypassed by the gnome utility mounting.

I am working in a CentOS environment with numerous CentOS machines. Currently there are multiple developers that each have their own login/home directory and then for various admin tasks we all share a single super user account.
The problem
I have a number of aliases, variables, functions, and settings that exist in my personal login's .bash_profile. None of these are available in the shared super user's .bash_profile. My current work around is that everytime I sudo in as the super user and I re-execute my .bash_profile from my personal user's home directory. I am not allowed to edit the init stuff for the super user
The Question
Is there any way I can automate my sudo sequence such that it will execute my personal .bash_profile after I've executed sudo without requiring me to edit the super user's bash init stuff?

So, I do not understand why the notification "sudo: cd: command not found", considering cd is a bash built-in command.

I would like to have an user that can execute al command with sudo.I configured sudo with yast2 and in the sudoers file actually there is a line with:USER ALL = (ALL) ALLWhere user is my username.But I can't use some command like ifconfig becouse it say that it can't find the command. I think that this is becouse of path, but shouldn't i get root path using sudo?

In Ubuntu 10.04, I logged in as user1 and when I open a new terminal and issue any command it is asking password.user@ubun-laptop:~$ sudo ifconfig[sudo] password for user: It is asking for password only for first time.From the next command onwards it is not asking.Can some one please tell me if it is possible to issue ONLY ONE COMMAND, in which even if the password request comes, it will automatically fill the password.Just like "ps -elf | grep NetworkManager". I am expecting any combination of commands in a single line, so that password is filled automatically IF PASSWORD IS ASKED. If password is not asked, the command must be executed.

In Ubuntu, When I type sudo and hit enter, the new command will appear on the command line, instead of simply executing. This is different from other operating systems I've used, such as older ubuntu's, mac osx and debian. Is there a way of disabling this confirmation and having it simply execute the command?

I'm trying to allow a specific group on my machine to execute one command with sudo without requiring a password, so what I want to do is add something like this to sudoers:
%groupName ALL = (ALL) NOPASSWD: /bin/bash /path/to/shfile.sh argument1 argument2
argument1 needs to be a url : http://subdomain1.subdomain2.domain.com
argument2 needs to be a path of the form /var/www/demo/SomeFolder/application/config/config.php
How do I put in a regex form that sudoers will understand ? I tried reading the sudoers manual, but it didn't help a lot .

I was wondering if someone had a logical reason and therefore complete, hopefully that makes total sense, for why when I install Ubuntu I cannot use the 'sudo' command either with root or user passwords. Even if I try to edit the permissions for sudoers, I still recieve an error message that says access is denied and so as the root user on my pc I don't understand why I can't put my name in the sudoers file or use the sudo command with the correct password.

Customer asked me to create a menu for linux he also asked me to do this: Open like a command like where a user can execute commands...so for this the users have sudo enabled. The code below works OK. But it has an issue when a command is executed but the command does not need sudo
Like for instance
Code:
cd /
sudo: cd: command not found
How can I allow a user to execute all commands when a command does not need sudo
Code:
echo -e "Press Control+C to finish"
#echo -e " "
while true;
do
read whichcmd?"Insert Command: "
sudo $whichcmd
done

I was trying to edit a file requiring root permissions, so I used sudo. I typed the root password and it failed. This happened three times, and the process was ended. I then logged in as root (su) and was able to navigate to the file and make changes as root. Am I missing something? How would I edit the sudoers file such that this password would work? Or is there another way to log in to the sudo group to make these changes? How do I set sudo passwords?

since a recent upgrade to Mandriva 2010.1 I am not able to 'sudo' as administrator or when I use the 'root' password. I am the only user on this machine (Dell Inspiron 530S multi-booted with Window's Vista Home Premium, Ubuntu 10.4, and Mandriva 2010.1). I can get into the 'Manage Users' section of the control center by authenticating as 'root' but I can't access 'sudoers file' from command line.

I have a script which builds a project and then runs junit tests. However, if the build fails, the junit tests fail with the same error message.Therefore the command which runs the junit tests should only be executed if the build was successful.

Before, the "sudo cp -r" command automatically set the permissions to make the directory / files can be accessed by others.
But, after I reinstall Ubuntu 9.10 and apply all the latest updates, "sudo cp -r" command set the files to be accessible by root only.
After I copy the codecs directory to /usr/lib by using the above command, not only I cannot view the files inside, SMPlayer and other player software cannot access the directory.
To fix this, I have to run the chmod command to change the permissions.
Does anyone face this problem? Was it caused by the installation of latest updates?

When I run sudo as a normal unprivileged user, it asks for my password, not the root password. That's often convenient, but it reduces the amount of information someone would have to have in order to run commands as root. So how can I make sudo ask for the root password instead of the invoking user's password? I know it'd be done with a line in /etc/sudoers, but I can never seem to properly parse the BNF grammar in the man page to figure out exactly what to write.

Can a sudo user do everything what a root user can do? I read sometimes expert say "You should run it as root rather than sudo user".

I want a quick and simple way to execute a command whenever a file changes. I want something very simple, something I will leave running on a terminal and close it whenever I'm finished working with that file. Currently, I'm using this: while read; do ./myfile.py ; done And then I need to go to that terminal and press Enter, whenever I save that file on my editor. What I want is something like this: while sleep_until_file_has_changed myfile.py ; do ./myfile.py ; done
Or any other solution as easy as that. BTW: I'm using Vim, and I know I can add an autocommand to run something on BufWrite, but this is not the kind of solution I want now. Update: I want something simple, discardable if possible. What's more, I want something to run in a terminal because I want to see the program output (I want to see error messages).

I finally got my path to save so apachectl is in my path. I can execute apachectl start as a regular user, although the server wont start because there is some sort of lock. When I sudo apachectl start , I get sudo: apachectl:command not found. My visudo file looks like this:Defaults env_keep += "PATH"

I've created a firewall with iptables rules and saved them into my bin directory (then changed them to executable) However i cant use "sudo firewall-start" it just prints a whole heap of garbage. When i use the "sudo firewall-start" command as root, it works perfectly. Im sure there's a simple solution to this problem, but cant seem to find one in the forums.

When I run '# sudo touch newfile' my expectation was that the file would be owned by me, not by root, as my understanding of sudo is that it is giving me, the user, root priviledges but does not actually switch the user.Do I have a fundamental misunderstanding of what sudo is about?
