Your question doesn't make a lot of sense, but if the permission is 000 none of the access bits are set and nobody can access the file. However, the root user is "special" in many ways, and depending on the implementation it's possible that root can access it (root can certainly change the permissions to allow him- or herself to access it).
It means you don't have the permission (or right) to access a file.
The main advantage is not really that it saves disk space (though it does that too) but, rather, that a change of permissions on the file is applied to all the link access points. The link will show permissions of lrwxrwxrwx but that is for the link itself and not the access to the file to which the link points. Thus if you want to change the permissions for a command, such as su, you only have to do it on the original. With copies you have to find all of the copies and change permission on each of the copies.
In Linux the chmod command is used to set file permissions.
To take ownership of the file that is locked or no permission granted.
It sets the access permission of a file. Allowing permission of a file to follow a certain path. It also will modify the mode bits and extends the access control.
use the chmod command syntax: chmod #### -option1 -option2 filename man chmod (for more information)
You need to check security settings for the drive. If your account is not on the list of allowed users, add your account to the list.
There are no folders within a file. Files are within a folder.
the command to make anything executable is chmod +x <file>
owner of the file
