ls -l "$1" | awk '{print $1}' | sed 's/^.//'

or if you need it with description:

script.ksh
Code:
ls -l $1  | awk '{print $1}' | sed 's/^.//' | sed 's/\(^...\)/owner:\1 group:/;s/\(...$\)/ others:\1/'

#script.ksh /tmp/test
owner:rw- group:r-- others:r--

Code:
set -- `ls -l "$1"`
perms=${1#?}
uperm=${perms%??????}
temp=${perms#???}
gperm=${temp%???}
operm=${temp#???}

That will work in any POSIX shell (including bash). It can be written more succinctly in bash (this also works in ksh93):

Code:
set -- `ls -l "$1"`
uperm=${1:1:3}
gperm=${1:4:3}
operm=${1:7:3}
