Understanding access permissions
Understanding access permissions
There are three types of permissions:
r read the file or directory
w write to the file or directory
x execute the file or search the directory
Each of these permissions can be set for any one of three types of user:
u the user who owns the file (usually you)
g members of the group to which the owner belongs
o all other users
The access permissions for all three types of user can be given as a string of nine characters:
user group others
r w x r w x r w x
