The ability to access a file is determined by a set of:

partitions

permissions

home directories of the user

directories

files

od -w filename' ADDS the write permission to the file filename.

True

False

This special permission which requires that the user owns the file in order to delete it is the letter (also known as the 'sticky bit'):

w

s

b

e

t

Permissions can be set on the user, group, or others.

True

False

Use this command to view the permissions on a file:

ls

ls -777

ls -ugo

ls -l

ls -i

To recursively descend through a directory changing permissions use the following command:

chmod -777

chmod -U

chmod -R

chmod -ugo

chmod -J

Setting the r permission allows the user to run as the owner of the file (e.g. the passwd command)

True

False

A directory created when the umask is set to 777 has FULL permissions (rwxrwxrwx)

True

False

The command 'chmod u=,g=,o= shortFileName' will set all permissions to rwxrwxrwx.

The valid modes for permissions are r=4, w=2, and x=1.
