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?

uudemon(4)						     Kernel Interfaces Manual							uudemon(4)

NAME

       uudemon.admin,  uudemon.cleanu,	uudemon.hour,  uudemon.poll  -	Administrative shell scripts for polling remote systems, cleaning up spool
       directories, reporting status to the system administrator, and routine invocations of the uuxqt and uusched daemons

SYNOPSIS

       These shell scripts reside in the following directory:
	  /usr/lib/uucp

DESCRIPTION

       All the scripts can be run from the command line or can be run automatically by the cron daemon. To automatically run the  scripts,  remove
       the comment character (#) from the beginning of the relevant line in the /var/spool/cron/crontabs/uucp file.

       This  script  reports  status  to  the system administrator. It issues the uustat command to find out the status of uucp jobs. It mails the
       results to the uucp login ID. The script may be modified to send mail to any login ID such as the uucp administrative login ID  (uucpa)	or
       root.  This script cleans up the /var/spool/uucp and /var/spool/uucppublic directories by running the uucleanup command. The uucleanup com-
       mand is run with the following parameters: -C7, -D7, X2, -o2, -W1.  This script runs the uusched and uuxqt daemons in the background.  This
       script  polls  the  systems  listed  in	the  /usr/lib/uucp/Poll file.  The uudemon.poll script should be scheduled before the uudemon.hour
       script. This allows uudemon.poll to create any command files before cron runs the uudemon.hour script.

FILES

       Contains the uudemon.admin, uudemon.cleanu, uudemon.hour and uudemon.poll files.  Contains the uucp file.

RELATED INFORMATION

       Commands: cron(8), uucleanup(8), uusched(8), uuxqt(1)

       Files: /usr/lib/uucp delim off
