Changing Permissions with Terminal Permissions is a largely invisible but hugely important Mac OS X and Unix feature. The behind-the-scenes permissions setting for a file or folder determines whether or not you re allowed to open it change it or delete it. Permissions are the cornerstone of several important Mac OS X features including the separation of user accounts and the relative invulnerability of the operating system itself. POWER USERS CLINIC The Termination of .term Files The ability to save different sets of windows settings is actually nothing new to Terminal. In earlier versions you could export a .term file that stored a window s or window group s settings. Opening the .term file opened a new window or window group with those settings. In Terminal 2 you get easier management for these settings and a different way of storing them. Instead of using a separate file for each setting Terminal now saves them all in the single file in Library Preferences . If you had any .term files in the standard location Library Application Support Terminal when you first opened Leopard s Terminal they still appeared in the Inspector but Terminal no longer reads them. Instead upon Terminal s very first launch those files settings are copied into the new file. That s why after the first time you open Terminal adding additional .term files to Library Application Support Terminal doesn t make them appear in the Inspector. To do that double-click the .term files in the Finder Terminal imports them. Double-clicking a .term file still opens a Terminal window using those settings. But if that s what you want why be so passé Instead double-click the newer .terminal files you get by exporting either your window or window groups settings. You ll find the Export command on the menu of both the Settings and Window Groups tabs of the Preferences panel. As you know from Chapter 13 you can get a good look at the permissions settings
