Given a three digit octal permissions number, output the permissions that it grants.
On UNIX OSes file permissions are changed using the
chmod command. There are few different ways of using chmod, but the one we will focus on today is using octal permissions.
The three digits in the permissions number represent a different person:
- The first digit represents the permissions for the user
- The second digit represents the permissions for the group
- The last digit represents the permissions for others
Next, each digit represents a permission as shown below in:
Key: number | permission 7 | Read Write and Execute 6 | Read and Write 5 | Read and Execute 4 | Read only 3 | Write and Execute 2 | Write only 1 | Execute only 0 | None
The input will be the three digit number as a string, e.g.:
This will be passed either via STDIN or via function arguments.
Your output should be the different permissions for each of the user, the group and the others. You must display this information like so:
User: ddd Group: ddd Others: ddd
Where there are three spaces after
User, two spaces after
Group and one space after
Others. You replace
ddd with the permissions information.
Your output may be to STDOUT or as a returned string.
User: Read and Write Group: Read and Write Others: Read and Write
User: None Group: Read only Others: Write only
User: Read and Write Group: Read only Others: Read only
The shortest code in bytes wins.
