Full Discussion: Running a script as root in the script

So, do you want anybody to be able to start the script, however if you detect that you are not the super-user account, you want to restart the script as the super-user instead?

Two quick options I can think of:-
  1. Make the script owned by root and set the SUID flag. Use chmod but add a leading 1 to the numeric description, e.g. if the file is rwxr-x---, then chmod 1750 filename
  2. Set everyone you want to up as a sudo user with NOPASSWD for this script, then add this to the top of your script:-
    Code:
    if [ $(id -u) -ne 0 ]
then
   exec sudo $0 "$@"             # Will overwrite this process so script does not continue as self
fi                               # Arguments are passed ass supplied

    Be very careful to explicitly grant users access to the script rather than a blanket 'run anything' else they will do things you don't want them to.


Do either of these help?

installsieve

INSTALLSIEVE(1) 					      General Commands Manual						   INSTALLSIEVE(1)

 *

NAME

       installsieve - user utility for managing sieve scripts

SYNOPSIS

       installsieve

DESCRIPTION

       installsieve is a utility that allows users to manage their sieve scripts kept on the server.

OPTIONS

       -v <name> View script with the given name. The script if retrieved sucessfully is output to standard output.

       -l  List  all  of  the scripts currently on the server. If one of the scripts is active a arrow is printed indicating that it is the active
       script.

       -p <port> Port to connect to. If left off this defaults to "sieve" as defined in /etc/services.

       -i <file> Install a file onto the server. If a script with the same name already exists on the server it is overwritten.  Upon  sucessfully
       putting	the  script on the server the script is set active. If <file> has the extension .script it is chopped when put on the server since
       sieve names may not contain a '.'.

       -a <name> Set <name> as the active script. The list of available names can be obtained from the '-l' option..

       -d <name> Delete the sieve script on the server with <name>.

       -m <mechanism> Force installsieve to use <mechanism> for authentication. If not specified the strongest authentication mechanism is chosen.

       -g <name> Get the sieve script with <name> and save it to disk with a ".script" extension. If a file with that name already  exists  it	is
       overwritten.

       -u <user> Userid/Authname to use for authentication; by default, the current user.
