Your answer should be the command you used to accomplish the task. Ensure to number

each step and type out the question.

Explain the permissions for the following files:

$1\mathrm{.}1$ drwx$-----6$ monette staff $4096$ Nov $182013$ twelve

$1\mathrm{.}2-$rw$------1$ kliu student $2495$ Sep $102013$ who.txt

a$)$ What type of file is it$?$

b$)$ Who is the owner?

c$)$ What is the group name?

d$)$ For each entry outline the permission granted to all type of users $($owner$,$

group, others$)$

For each of the following explain what permissions are granted. A file with:

$2\mathrm{.}1777$ permissions

$2\mathrm{.}2655$ permissions

$2\mathrm{.}3455$ permissions

In the previous question which permission is the riskiest $-$ why? Which of the above

permission is safest $-$ why?

For the file $-$rw$-$wx$-$rwx foo.txt$,$ use symbolic representation change the permissions so

that

a$)$ The Owner and the group do not have any permissions. Others can open it$.$

b$)$ The owner can write to it$.$ The group can open it$.$ Others will not have any

permissions.

c$)$ Only others have permission to open it$.$
