Pushing out a script to run via ARD

Question

I have the following script I am running into two issues with
1)  Instead of running it as root, can we run as a member of the admin group.
2)  Can this be pushed out via ARD?
#!/bin/bash
#This script needs to run as root
ROOT_UID=0
if [[ $UID -ne $ROOT_UID ]]; then
echo "YOU MUST BE ROOT TO RUN THIS SCRIPT"
exit 1
fi
OLD="<string>The owner or any administrator can unlock the screensaver.<\/string>"
NEW="<string>(Use SecurityAgent.) The owner or any administrator can unlock the screensaver.<\/string>"
cp /private/etc/authorization /tmp/auth.tmp
sed "s/$OLD/$NEW/" /tmp/auth.tmp > /tmp/authorization
mv /private/etc/authorization /private/etc/authorization.previous
mv /tmp/authorization /private/etc/authorization
rm /tmp/auth.tmp

Answer 1

Do not remove the "root user reference" from the script. Without "the reference" the script will place a modified authorization file in the /tmp directory. To modify the /private/etc/authorization file you must be root or an admin user with the proper authorization (You would use sudo in the shell environment). Here's a safer and cleaner version of that script->
#!/bin/bash
OLD="<string>The owner or any administrator can unlock the screensaver.<\/string>"
NEW="<string>(Use SecurityAgent.) The owner or any administrator can unlock the screensaver.<\/string>
# use sed to make a backup of the original file then edit the file in place
/usr/bin/sed -i.previous "s/$OLD/$NEW/" /private/etc/authorization
