do
$ll|awk '{print $9}' to see the filename
$ll|awk '{print $4}' to see the group

you can have similar combinations to view each field is represented by "$" starting from 1 to 9

Hi nash11,

# ls -l | cut -f2
for file owner's group

# ls
gives filename alone.

# man cut
for more info.

Should be:

# ls -l | sed 's/ */ /g' | cut -f4 -d" "

But:

# ls -l | awk '{print $4}'
# ls -l | perl -nea 'print "F[3]\n"'

are more succinct.
