Multiple variables from one command
I have the following bit of code

FOUND_SEC=`ls -ld $NAME 2>/dev/null|awk '{print $1}'`
FOUND_USER_NAME=`ls -ld $NAME 2>/dev/null|awk '{print $3}'`
FOUND_GROUP=`ls -ld $NAME 2>/dev/null|awk '{print $4}'`

is there a better way to write it to get the same result as it seems silly to me to run the ls command three times when I get the same results

Code:
set -- $(ls -ld "$NAME" 2>/dev/null)
FOUND_SEC="$1" FOUND_USER_NAME="$3" FOUND_GROUP="$4"
