They cannot list the contents of the directory. To see the names in a directory from inside the directory means the directory needs r-x permissions; to see the same thing using an absolute path to the directory needs only r-- permissions on the directory.
They do need to log off and log on again, and group permission is granted at logon time.
These permissions are determined by 9 bits in the i-node information, and are represented by the characters "rwxrwxrwx. In this document, we discuss permissions as they apply to ordinary, non-root users.
It would be listed as xrwx 1 jo guests 0 Feb 1 Now, the file looks like this: Each of these three numbers is, in turn, formed as a 3-digit binary number where the first digit is the read permission, the second is the write permission, and the thrid digit is the execute permission.
Group A user- group can contain multiple users. See below for special setuid and setgid programs that do not inherit your user IDs when you run them. User A user is the owner of the file. Sun supports both mechanisms for backwards compability.
The permissions on the directory inode apply, not the permissions on the inode of the thing to which you are making a link. Instead, the character representation is used. The Video will load in some time. Read permission on a directory only gives the process access to the names in the directory itself.
It is used to reduce the start up time when executing a program. Click the lock and authenticate with an administrator account. One way to gain entry when you are denied permission is to su to root.

When I run chmod +w filename it doesn't give write permission to other, it just gives write permission to user and group. After executing this command chmod +w librariavagalume.com running ls -l testfil.
will give owner and group full access, but take access from the "others". Its pointless to give them write and execute access though if they can't read it (needed to view contents) so you may as well use chmod as opposed to or the like.
Modify User Permissions. File permissions on Unix and Linux are one of the most ubiquitous stumbling blocks for even regular users of those operating systems.
Unix and Linux operating systems assign access rights to files and directories using one of three types of access (read, write and execute) assigned to each of three groups (owner, group and other users). The values for the access rights for each of the groups is added together to obtain a value.
