Bitmask permissions

**It's a tutorial problem in a Linux course**: The command

-la /

gives this result:

The command

ls -lR /something

produces this result:

/something:
total 4
drw-r-xr-x 3 george george 4096 Apr 16 14:24 one

/something/one:
total 4
drwxr-xr-x 2 george george 4096 Apr 15 23:47 two

/something/one/two:
total 4
-rwxrwxrwx 1 george george 7 Apr 15 23:47 somefile

We work under the user

, i.e. the command

gives us

. The

george

command gives us the result

: george users

. What result do we get for the

/something/one/two/somefile

command and why? **My attempt to solve the problem**: **1. Let's see what access rights we have to somefile:** The file

has

-rwxrwxrwx

rights, hence the users **user, group and other** have all the rights to read, write and execute this file.Hence, the user **george** can read this file. **2. Let's make sure that somefile exists:** Running the

ls -lR /something

command displays a list of all files and subdirectories in the

/something

directory, including permissions information and file size, with superuser privileges. The file is located in the

/something/one/two/somefile

directory. **3. Let's check the access rights of the directory /something/one/two/somefile :** Directory

has access rights

-r-xr-x

- user **george** has permission to enter this directory, and read the contents; Directory

has

-xr-x

access rights - user **george** has permission to enter this directory, and to read the contents; By executing the

/something/one/two/somefile

command we will be able to view the contents of the

. The

-l

command shows that the ``somefile` file weighs 7 bytes. If the file contains text or characters, they will be displayed in the console. **My mentor says these hypotheses need to be tested.** **How do I test this task?**
