General :: Execute A Command After Sudo?
May 4, 2011
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?

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 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, 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 .

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

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.

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"
User_AliasOWnER=blake
root All=(ALL) ALL
OWNER ALL= NOPASSWD:ALL

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.

My laptop has a dead battery. Even when it's fully charged, if the power cable is pulled out it only lasts for about 4 minutes before it dies. I'm running Ubuntu Lucid Lynx 32-Bit. What I want to do is create some sort of script or program that will immediately set my computer to go into hibernation once it detects that the power cable has gone dead. I'm willing to look into all ways of doing this. I can program in C, but I'm not familiar with the API used to manage Power Management in Linux.

I have succesfully installed Debian with gnome-core, iceweasel and other useful packages and also followed this guide to autologin and start X. I noticed that the sudo chmod +s /sbin/halt and adding /sbin/halt
in ~/.bashrc made Debian refuse me to log out (from X) and 'log out' turns off the computer insted.Removing /sbin/halt from .bashrc turned everything to as i want it. Should I "repair" or remove something I created with chmod +s command or should I leave it as it is?
Also I would like apt-get(or aptitude) update to run after login (and before startx), so i added sudo apt-get update to .bashrc but it will prompt me with password. Is there someway I could do this without the password(s) which su/sudo needs to execute? This is not so important but it would be very nice to update the system on startup.

I have an alias that I would like to use both as a regular user and as root, via sudo. Specifically, it is this:
alias rm=trash This works fine as a normal user, and it works fine when I use sudo -i to get a root shell prompt, but if I use sudo rm, the alias does not apply. So where do I need to put my alias so that it works in one-off sudo commands?

I am working at a client who has a project where code is a mixture of different source control systems. So a layout might be like this
project/a/.svn
/a/subfolder/.svn
/b/.hg
/c/subproject/.svn
/d/.hg
So I am trying to put together a simple command that when executed from the project folder will run the appropriate hg/svn command in each project i.e:
[Code]...
Since the client has many such projects, Instead I am looking for a solution similar to find -exec where the svn/hg commands are automatically executed on each first level of match (i.e. svn up is run in the project/a folder but not in project/a/subfolder). How can such a command be constructed ?.

I've been using SuSE for a while and something has been bugging me. Not a show stopper, but nevertheless, an interesting one. Most tutorials, forum posts, etc. recommend using a sudo command to accomplish stuff. For example:
Code:
sudo make install
sudo vi file
However, this does not always work. For instance, I was recently working on a resolution problem with my ViewSonic VX922 - it would only display at 1024x768 rather than the native 1280x1024. Viewing some posts, I found the command "sudo sax2 -r". What I discovered is that there seems to be a big difference between sudo and su
Code:
drkhelmt@SPACEBALL1:">sudo sax2
root's password:
sudo: sax2: command not found
drkhelmt@SPACEBALL1:">su
Password:
SPACEBALL1:/home/drkhelmt: #sax2
SaX: Checking update status for intel driver
SaX: initialization already done
SaX: cal [ sax2 -r ] if your system has been changed !
SaX: startup
SaX: X server:0.0-> grant
SaX: importing current configuration
SPACEBALL1:/home/drkhelmt: #
So the question, why does the command sax2 (and others) work when after the su command rather than a sudo?
