Well I can give you an example how I setup command alias in /etc/sudoers file for our ID Administration team. This is what it looks like:

Code:

Cmnd_Alias      IDADMIN=/usr/bin/mkuser, /usr/bin/chuser, /usr/sbin/rmuser, \
                /usr/bin/passwd [0-9]*, /usr/bin/passwd [A-z]* ,\
                !/usr/bin/passwd root, \
                /usr/bin/chsec, /usr/bin/mkgroup, /usr/sbin/rmgroup, \
                /home/comadm/passwd_lastupdate.pl, \
                /usr/bin/ls, /usr/bin/chmod, /usr/bin/chown, /usr/bin/chgrp, \
                /usr/bin/find, /usr/sbin/lsuser, /usr/bin/vi /etc/ftpusers, \
                /usr/local/bin/generate_user_file_list, \
                /usr/local/bin/remove_user_files, /usr/bin/cat, \
                /usr/bin/rm -f /var/spool/mail/*, \
                ! /usr/bin/rm -f /var/spool/mail/root, \
                /usr/bin/rm -f /var/spool/cron/crontabs/*, \
                ! /usr/bin/rm -f /var/spool/cron/crontabs/root, \
                /usr/bin/rm -f /var/spool/cron/atjobs/*, \
                /usr/bin/rm -rf /home/*, /usr/bin/pwdadm, /usr/bin/smitty user

With command alias you can not only create positive set of list but also you can specify what they cannot do using sudo (as opposed to what zaxxon said, note the exclamatory sign in front of commands which are being restricted).

Hope you get an idea on how to set up /etc/sudoers

audswitch

audswitch(2)							System Calls Manual						      audswitch(2)

NAME

       audswitch() - suspend or resume auditing on the current process

SYNOPSIS

DESCRIPTION

       suspends or resumes auditing within the current process.  This call is restricted to users with the privilege.

       One of the following flags must be used for aflag:

	  Suspend auditing on the current process.

	  Resume auditing on the current process.

       can be used in processes with the privilege to temporarily suspend auditing during intervals where auditing is to be handled by the process
       itself.	Auditing is suspended by a call to with the parameter and resumed later by a call to with the parameter.

       An call to resume auditing serves only to reverse the action of a previous call to suspend auditing.  A call to	to  resume  auditing  when
       auditing is not suspended has no effect.

       affects	only  the current process.  For example, cannot suspend auditing for processes from the current process.  (Use (see setaudproc(2))
       to enable or disable auditing for a process and its children).

   Security Restrictions
       Some or all of the actions associated with this system call require the privilege.  Processes owned by the superuser have  this	privilege.
       Processes  owned  by  other users may have this privilege, depending on system configuration.  See privileges(5) for more information about
       privileged access on systems that support fine-grained privileges.

RETURN VALUE

       Upon successful completion, returns If an error occurs, is returned and the global variable is set to indicate the error.

ERRORS

       fails if one of the following is true:

       The user does not possess the
		      privilege.

       The input parameter is neither
