Help with Shell Script on sudo

I want to execute a script( which resides on root home directory from shell script( as root by using sudo.

The thing is
i cant edit /etc/sudoers (i can but m not allowed to do it , ethically)
i cant change ownership of script

When i try to run command using
sudo ./ $1 $2 $3 $4 $5 $6

in the script

i get this error
Sorry, user xyz is not allowed to execute './' as root on usrdts.

i have no problem even if sudo asks for a password when i run

Please help me out.

Thanks in advance.

You will need to edit /etc/sudoers to include the user information.

#/etc/sudoers - use visudo to edit the file
#without passwd
xyz  ALL= NOPASSWD:/full/path/to/

#with passwd
xyz  ALL= PASSWD:/full/path/to/

thanx for reply

yes i know,
i have tried it earlier and it works but
this is not the solution which i can implement due to some policies.

Do u know any other solution????

sudo is doing precisely what it's designed to do -- preventing users from running something as root unless properly authorized. If you're not permitted to edit sudoers, and you're not authorized, you're not authorized. If there was a way "around" this, it would be a gaping security hole needing to be fixed as soon as possible.

So, you'll need to use means that aren't sudo. Can you su or sudo su ?

If it was a binary program you could set it setuid and it'd always run as root, but this doesn't work for shell scripts.

i do have priviledges
to edit sudoers file
to execute sudo su

and frankly i dont want to exploit any security hole nor interested in finding one.

The thing is this script is going to execute in production env. and due to security policy we are requested not to edit sudoers file.
i cant change ownership of that script.

do u need any more information for finding a appropriate solution.
please do tell..Smilie

and thnx for reply

If you can't use sudo and can't use su and can't use setuid, you're not going to be able to run it as root. They'd likely consider it circumventing their security rules in any case.

Why does the script need root? Maybe the permissions on whatever it needs can be altered so it doesn't.

again i really appreciate ur help.

i can use sudo but cannot edit sudoers file.

here is brief intro of situation
the script is created by me (user xyz) and is kept in another user ( abc ) home directory. ok .
the script want to read some files which abc users have access to.

the current situation is i execute command
 sudo su - -s /bin/bash abc

and then access the files

i want to automate this process in script
so when i
 sudo ./ $1

it asks my password which i provide then after logging in it produces error as specified in my 1st post. ( user xyz execute script as root on user abc )

i can talk with user abc for some changes if they are minor.
