OWNER LEE.BALLANCORE YES YES NO
GROUP USERS YES NO NO
EVERYBODY NO NO NO

This should get you started:

Code:

permreport()
{
  printf "%s\t" "$1"
  shift
  r=${1%??}
  wx=${1#?}
  w=${wx%?}
  x=${wx#?}
  for p in $r $w $x
  do
      case $p in
          -) printf "NO \t" ;;
          *) printf "YES\t" ;;
      esac
  done
  echo
}

FILE=$1
set -f
set -- $( ls -ld "$FILE" )

type_perms=$1
links=$2
owner=$3
group=$4
size=$5
month=$6
day=$7
time=$8 ## may be year
filename=$9 ## may include symlink target

perms=${type_perms#?}
filetype=${type_perms%"$perms"}
goperms=${perms#???}
uperms=${perms%"$goperms"}
gperms=${goperms%???}
operms=${goperms#???}

permreport OWNER $uperms
permreport GROUP $gperms
permreport WORLD $operms

Note that this doesn't take into account setuid and README bits.

console.perms

console.perms(5)					   System Administrator's Manual					  console.perms(5)

NAME

       console.perms - permissions control file for users at the system console

DESCRIPTION

       /etc/security/console.perms and .perms files in the /etc/security/console.perms.d directory determine the permissions that will be given to
       priviledged users of the console at login time, and the permissions to which to revert when the users  log  out.   They	are  read  by  the
       pam_console_apply helper executable.

       The format is:

       <class>=space-separated list of words

       login-regexp|<login-class> perm dev-glob|<dev-class> 
	       revert-mode revert-owner[.revert-group]

       The revert-mode, revert-owner, and revert-group fields are optional, and default to 0600, root, and root, respectively.

       The  words in a class definition are evaluated as globs if they refer to files, but as regular expressions if they apply to a console defi-
       nition.	Do not mix them.

       Any line can be broken and continued on the next line by using a  character as the last character on the line.

       The login-class class and the login-regexp word are evaluated as regular expressions.  The dev-class and the dev-glob word are evaluated as
       shell-style globs.  If a name given corresponds to a directory, and if it is a mount point listed in /etc/fstab, the device node associated
       with the filesystem mounted at that point will be substituted in its place.

       Classes are denoted by being contained in < angle bracket > characters; a lack of < angle brackets > indicates that the	string	is  to	be
       taken literally as a login-regexp or a dev-glob, depending on its input position.
