Ubuntu :: Bash Sudo Scripts Fail To Work After Install Of 10.04

Aug 4, 2010

I had some bash scripts on Ubuntu 09.10 (mint version) that fail to work on Ubuntu 10.04. The line that fails is the following:

Code: # cat file_with_my-password.txt > sudo -S something cat: invalid option -- 'S' Try `cat --help' for more information. In my case "something" mounts some filesystems (that fail to load from fstab - bios "fake" raid 10), but I get the same error for any sudo command. It is the same script that used to work under 09.04 :-/

Programming :: SU And Sudo Within Bash Script

Oct 27, 2010

I'm working on a script which handles disaster recovery for a system I'm developing. Part of the script will also be used for initial setup. It needs to require as little user interaction as possible. It also needs to be run as root during most of the process. The problem is that there comes a point where some of the software can't be compiled or installed as root. So root needs to su to a regular user who then has to sudo in order to compile & install the aforementioned software. After all this, the script needs to revert to it's original state, running as root. I've never encountered a situation where root had to su to a normal user in order to sudo as root.

OpenSUSE Install :: Revert The Changes Or Change The Permissions Again To Root:root Or Make Sudo Work

Aug 10, 2011

Accidentally I changed the ownership of all the directories under / to my own instead of root:root. Now I am unable to use sudo and many bad things are happening. Is there a way to revert the changes or change the permissions again to root:root or make sudo work ?

Fedora :: Run (not Run In Terminal) Bash Script With Sudo In It?

Jul 6, 2010

I have written a tiny script which switches between 2 CPU frequency throttling governors. Now I need to assign it to a shorcut key though "Preferences->Keyboard Shortcuts".

Here is the script:


if [ `cat /sys/devices/system/cpu/cpu0/cpufreq/scaling_governor` = 'ondemand' ]


As you can see this script involves sudo. I know that usually running commands with sudo requires "Run in Terminal" option for a shortcut, but in "Keyboard Shortcuts->Add" there is no option to run command in terminal. When I double click on the script and choose "Run in Terminal", then it functions as it should. How can I make this script execute by doing "Run" and not "Run in Termnal"?

Programming :: Bash Scripting With Sudo / Password Prompt And Accepting User Input?

Jul 30, 2011

I'm creating a bash script to do some tasks for me. I would like the script to be run at a set time of everyday. My first question is if it is possible that if one of the commands in the script requires sudo, is there a way to get around it with out making sudo not require a password. Such as, is there a way to include the password in the script? If that is the case, I can always just set the file as read only by sudo. I've been looking for a way to do this, with no success. if I have a command that wants input, how do I give it to the program. For example, if I want to make a zip file that is encrypted, the command would go as:


zip -r example * -e

now how would I get the script to insert my wanted password.

Ubuntu :: Administration Functions And Automatic Update Fail To Work?

Mar 27, 2010

I am using Ubuntu 8.04. Most of my Administration functions have stopped working. If I click on Hardware Drivers, Hardware Testing, Log In Window, Software Sources, Synaptic Package Manager, and Windows Wireless Drivers my pointer turns into the timer wheel, so I know it is working, but then it just disappears and nothing happens. When I click on Update Manager my computer freezes. If I try to update through the red Updates Available arrow at the top of my screen my computer freezes. I can update through terminal but the red arrow never goes away. I also have 17 updates that won't update. I have tried them one at a time through terminal but they just freeze the computer. The only way to unfreeze it is to shut the computer down.

Ubuntu :: Su Command Won't Work, But Sudo Will?

Oct 16, 2010

I was attempting to install the fglrx driver on my new ubuntu insallation, following a guide I found from google. At one point it says I need to login as super user, so I tried and no matter how many times I try it just keeps saying authentication failed. I even tried typing in my password with 1 finger, multiple times, every single time, authentication failed. So I decided to try the sudo command with fdisk -l, worked flawlessly. Tried the su command again, authentication failed, I have no idea what in heck is causing this but it just won't stop happening.

General :: Ubuntu / Sudo Also Doesn't Work

Jun 30, 2011

I have ubuntu server 8.x which works Ok but the other day I changed the owner of some files "the directory /etc" from root me. Now a lot commands do not work like reboot and such. So I tried to put ownership back to root and I can't. I say I dont have proper privilege. Sudo also doesn't work. I conect to the server using ssh with putty. What could I do to fix the problem? Update to the new version? This server has been working really well for a few years. The reason I changed the owner of the directory to myself is so I could edit some config files from my windows machine using a FTP client like WinSCP.

Ubuntu :: Getting Keebox W150nu To Work With 11.04 - Sudo Password

May 9, 2011

I'm a totally new Linxu/Ubuntu user and terrified of command prompt/terminal. But I'm trying to get my Keebox W150nu to work with 11.04 and following Chili's suggestion on doing so, but ran into an early problem:

robert@lawsonbox:~$ ndiswrapper -1
The program 'ndiswrapper' is currently not installed. You can install it by typing:
sudo apt-get install ndiswrapper-common
robert@lawsonbox:~$ "sudo apt-get install ndiswrapper-common"
[sudo] password for robert:

At that last line I am stumped. I can't input anything, no matter what key I press nothing is showing up there. If I knew the password I wouldn't be able to put it in! Do I hit an F key or what at this stage?

Fedora Hardware :: Sudo Does Not Work With Fingerprint (SU Still Do)

Jan 20, 2010

Since yesterday my sudo doesn't work with my fingerprintreader anymore. su and GDM still do. sudo just asks me for the password instead of asking for a finger-swipe. AFAIR I changed nothing, but I accidentally forwarded the USB-Port on which the scanner is connected to VMware. I disconnected it, but maybe there could be the problem.

Ubuntu Security :: After Booting Up From The Restored Filesystem - Sudo Would No Longer Work

May 28, 2010

I'm having some trouble using sudo - it did work fine, but now when I try to use it, I have the following error:

I understand that I have to modify /etc/sudoers but need to have root access to do this. I am using a bootable USB (lucid) with persistent changes and am unable to login as root, because I don't know the default root password, and am unable to use sudo to change it.

The problem occurred after I had some corruption to the casper file system, so I booted into Windows, moved the casper-rw file to another location on my flashdrive, and used a 1GB backup filesystem to repair the corrupt one using fsck.

After booting up from the restored filesystem, sudo would no longer work.
