Question

Linux, please

avocado is an empty file

Q14 – Specify a single line command that gives the owner and group permission to execute the file avocado while giving the owner sole permission to read and write the file. Do not change any other permission, i.e., do not remove permission from others to execute the file, if they already have that permission.

Q15 – File/directory permissions are subject to permissions on the parent directories. For example, consider the file /home/dv35/cs265/lab1.txt. If I wanted to allow others to read that file, then I would give 644 permissions to the lab1.txt file, so others have read permission on that file. But that would not be enough. The directory /home already has 755 permissions. I also would need to give what permission to dv35 and cs265 directories, so others have permission to visit it?

chmod u=+rwx,g=+x avocado

Answer 15
***********
home directory is having highest permission 755 means read ,write ,execute ; read execute; read execute for user , group and other respectively now if you give permission 644 which is already less then 755 so no need give specific permission to directory as lab1.txt set 644 .
