The next three characters correspond to the user's own permissions. The three following that specify the group's permissions and the last three show the general world permissions:
user group world - r w x r w x r w x
(Protections can be set with octal numbers, representing the three bits in each field. Thus rwxr-xr-x, the typical permissions on an executable file correspond to the octal number "0755". Similarly, rw-r--r-- corresponds to "0644".)
