How to manipulate File Sharing Permission in MAC

**Caiden** · 05-02-2010

Hi,
I have noticed that MAC OS X has one of the most common problems is the management of rights which are used to access files. It happens quite frequently not able to achieve a particular action because we do not have the necessary permissions. The problems are like facing permission problems on files or not able to read or write in a directory or cannot edit a file. This lies with the sharing of files on a MAC network.

Most of the problems can be solved directly in the GUI of Mac OS X by making an apple + i on the file that is problematic, and by changing the settings available at the bottom of the window that appears. The same is possible to do so with great precision via the Terminal with the command chmod. If you have a bit information on this then you can go with it.

The user account is defined in the form of / etc / passwd. The user group defined in / etc / group, allows group users into groups (one user can belong to several groups) for instance to share permissions with multiple users. These groups and users are modifiable through open Netinfo Manager in / Applications / Utilities, or the Terminal. The rights of access to a file are modes of this file is predefined.

A file has 3 levels of permissions, 3 ways to access it. They are reading, writing and execution. You can view these permissions through the information accessible via the Finder (apple-i or in the Finder, File menu, display information), but also by the Terminal with thecommand ls-l, we add the option to ls to obtain a long list (see article on ls) and then see the file permissions.

Under Leopard, file sharing has been greatly simplified. Just turn on sharing in System Preferences Sharing category. By default, all Macs Network will appear directly in the Finder, but it will access only the Public folder (deposit box). To share another folder it will add the folder. You can easily add accounts virtual, ie only for access to your files being shared, even if they do not have accounts on your physical computer. The option button will set the type of sharing (for connection type afp or smb FTP)

Modes and permissions are one of the most complex aspect of Unix, and thus Mac OS X. It should therefore spend some time studying this operation. But if indeed this management rights over the Terminal you seem a little obscure. I will recommend to go on the Apple Site and study on this matter. This are sometime most complex.
