Write a shell script which displays the last modification time if the file exists and a suitable message if it doesn’t.

for var in $@
do
check=`ls -al $var 2>/tmp/err | grep -w $var | cut -d " " -f 9`
if [ "$check" == "$var" ];then
mod_time=`ls -l $var | cut -d " " -f 6,7,8`
echo "***Last modification time of file $var***"
echo "$mod_time"
else
echo "$var file doesnt exists"
fi
done
