Assume that you want to let members of your group and other users access a directory named $/$mnt$/$netshare$/$shire$.$ The members of your group and other users should also be able to see a listing of files in the directory, but they should NOT be able to create new files or delete files in the directory. Also assume that you will have full permissions to this directory. What number would you give to chmod to accomplish this? Note $$ only enter the $3$ digit number for the permissions, do not enter chmod or the directory name.
