Write a short script that tells you whether the permissions for two files, whose names are given as arguments to the script, are identical. If the permissions for the two files are identical, output the common permission field. Otherwise, out- put each filename followed by its permission field. (Hint: Try using the cut utility.)

Question

What will be an ideal response?

Answer 1

The following code is the heart of this script. As always, you must specify
a shell and check the arguments.
$ cat permcomp
perm1=$(ls -l $1 | cut -d" " -f1)
perm2=$(ls -l $2 | cut -d" " -f1)
if [ $perm1 == $perm2 ]
then
echo $perm1
else
echo $perm1 $1
echo $perm2 $2
fi
