Write a shell script that accepts two file names as arguments, checks if the permissions for these files are identical and if the permissions are identical, output common permissions and otherwise output each file name followed by its permissions.

if [ $# -ne 2 ]
then
echo "No arguments"
elif [ ! -e $1 -o ! -e $2 ]
then
echo "FIle does not exist"
else
p1=`ls -l $1|cut -c2-10`
p2=`ls -l $2|cut -c2-10`
if [ $p1 == $p2 ]
then
echo "File permissions are equal & is $p1"
else
echo "File permissions are not equal"
echo "1st file $p1"
echo "2nd file $p2"
fi
fi
