Syntax

tell app "File Sharing"
   (* find out about the first user connected to your machine *)
   name of connected user 1
end tell

Dictionary commands

close reference to object

You can close a File Sharing window used to set or alter the privileges for a user or group:

close user "Guest"

This window can be opened from the Users & Groups tab by selecting the username and clicking the Open button (AppleScript cannot open this window, however).

delete reference to object

You can delete a user or group:

delete user "temp"

You should not allow important network script commands like delete or make to fall into the wrong hands.

duplicate list

You can create a new user or group with the same privileges as another user or group with duplicate. The following example duplicates a user and gives the new user a name:

tell application "File Sharing"
   activate
   set nw_user to duplicate user "iMarc"
   set name of nw_user to "iMarc2"
end tell

make

This command makes a new user, but the with data parameter that is identified in its dictionary does not work.

new user or group

You can make either a new user or group; you cannot make a new shared item.

with data anything

Alas, this parameter does not work properly with making new users or groups in AppleScript 1.4, but I include it anyway because it appears in the File Sharing dictionary. The next example shows user- and group-creating code that does work:

tell application "File Sharing"
   activate
   set group_name to "graphics"
   set user_name to "Van Gogh"
   (* make the group first *)
   set n_group to make new group
   set name of n_group to group_name
   (* make the user *)
   set n_user to make new user
   set name of n_user to user_name
   set can connect of user user_name to true
   set can change password of user user_name to true
   set can do program linking of user user_name to false
   (* add the new user to the new group *)
   add user user_name to group group_name
end tell

disconnect list of connected users

You should be able to use this command to disconnect a specified user, but under Mac OS 9 none of the following commands have worked properly:

disconnect {connected user 1}, disconnect connected user 1,
disconnect  connected user "iMac," disconnect (connected user whose id =
131082}

Well, you get the picture. I am in search of a workaround or solution to the disconnect command.

show privileges of list of shared item objects

On my computer, the File Sharing control panel exposes just two shared items to AppleScript; both are disks. Neither shared item responds without an error to the show privileges of command, as in:

show privileges of (shared item 1)

add reference to object

You can add a user to a group with this command.

to reference to object

This labeled parameter involves the keyword to followed by a reference to a group:

add user "new_user" to group "new_group"

remove reference to object

You can remove a user from a group with this command:

remove user "defunct" from group "graphics"

from reference to object

Follow the from label with a reference to a group:

remove user "defunct" from group "graphics"

Dictionary classes

application

This class represents the File Sharing control panel. It has two elements that represent the users who are connected to your computer and the shared items on the machine, such as hard disks. You get access to File Sharing by targeting the app in the tell statement, as in:

tell app "File Sharing" to get connected
users

The following are application elements:

connected user

The connected user object represents a user who is connected to your machine via File Sharing. See the connected user class later in this chapter for a description of its properties.

shared item

A shared item is an element such as a disk that can be shared via File Sharing. The only property that can be accessed with your script is its name. For example:

tell app "File Sharing" to get name of shared item
2

The following are application properties:

frontmost (boolean; read-only)

This is true/false value indicating whether File Sharing is the desktop's active application (i.e., its windows are highlighted):

tell app "File Sharing" to get frontmost

name (international text; read-only)

The name property returns "File Sharing."

version (international text; read-only)

The version property returns a value such as "9.0."

file sharing (boolean)

If File Sharing is turned off on your computer (i.e., network users cannot get access to your disks and folders), then this property returns false; otherwise true.

sharing starting up (boolean; read-only)

When you turn File Sharing on, the app can take several seconds to complete the task. If File Sharing is not undergoing its startup routine, then this property is false.

program linking (boolean)

If a user has program-linking privileges (which are set in the Users & Groups tabbed panel of File Sharing), then she can execute applications that reside on your machine. The program is actually executed on her connected machine, even though its binary executable code resides on your machine. The program-linking user cannot open applications that are already open on your machine, however. For example, if user "Gill" does not have Photoshop 5 on her machine but you do, Gill can access this program on her machine if that privilege is configured for her and program linking is on. You can stop program linking from the File Sharing control panel, as well as determine whether the users connected over TCP/IP can use program linking. For instance, you can stop program linking with script by setting this property to false:

tell app "File Sharing" to set program linking to false

owner name (international text)

This property returns the text from the Network Identity section of File Sharing's Start/Stop tab. If the owner of File Sharing privileges on your computer is called Admin, this property returns "Admin."

owner has password (boolean; read-only)

If the owner name identified in the File Sharing control panel has a password then this property returns true.

computer name (international text)

This property returns the computer name from the Network Identity section of File Sharing's Start/Stop tab.

connected user

This class represents a user that is connected to your machine via File Sharing. The available properties are its name, as in:

connected user "G4Power"

and its ID number. The code:

tell app "File Sharing" to get connected users

will return a list type, as in:

{connected user "G4Power" of application "File
Sharing"}

name (international text; read-only)

This property returns the user's name as text, such as "graphicsUser1."

id (integer; read-only)

Every user has an id number of the form 65546.

shared item

This class represents a item than can be shared via File Sharing, such as a disk. Use the code:

shared items

to get a list of these resources, which looks like:

{shared item "my2gig" of application "File Sharing",
shared item "Macintosh HD" of application "File
Sharing"}

name (international text; read-only)

This command returns a shared-item name as text, such as "my2gig."

group

The group class represents a group-sharing entity that can be created with File Sharing. The permissions can then be configured for each group from the shared element's Get Info window. For example, you might give the "Graphics" group read-only privileges on the disk "my2gig." File Sharing groups can be referred to in AppleScript by their name, as in group "Graphics." The code

tell app "File Sharing" to get groups

returns a list type with each one of the groups as a member of the list. The multi-line code example earlier in this chapter shows how you can make a new group.

name (international text; read-only)

This property returns the name of the group as text.

id (integer; read-only)

Every group is distinguished by an id number like 17.

user

user objects represent the users that are configured in your File Sharing control panel. They are distinguished from connected-user objects, which are only created when a user has actually connected to your computer. Users have names, IDs, and a few other properties that can also be set in the File Sharing control panel.

name (international text; read-only)

This is the name of the user as text, as in "graphicsUser1."

id (integer; read-only)

Every user has an id number of the form 18.

can connect (boolean)

If you do not want to allow a user to connect to your machine, set this property to false:

set can connect of user "virusMan" to false

can change password (boolean)

Set this property to true if you want to allow users to dynamically change their passwords (they have to know the original password to create a new one).

can do program linking (boolean)

This property can be set to false if you do not want to allow users to execute your applications.

see entire disk (boolean; read-only)

Only the local File Sharing owner, who is also a user, can have this property set to true. You can find out whether they have this privilege with the following code:

set sed to see entire disk of user owner
name

The owner name property returns the local owner's name as text, so they can be identified in script code:

user owner name

Examples

(* make sure this variable can be accessed from anywhere in the script *)
global cu
tell application "File Sharing"
   set cu to connected users -- returns a list of connected users
end tell
(* this subroutine writes user names to a file if there is at least one connected user *)
writeUsers(  )
on writeUsers(  ) -- subroutine definition
   set ulength to (length of cu) -- number of connected users
   if ulength is greater than 0 then
      tell application "Finder"
         activate
         set tf to (make file with properties {name:"connected users", ¬
         file type:"TEXT", container:desktop}) -- make this log file
         set tf to tf as alias
      end tell
      open for access tf with write permission (* use osax from Standard 
Additions *)
      write ("Here are the connected users:" & return) to tf
      repeat with n from 1 to ulength
         write ((name of item n of cu) & return) to tf
      end repeat
      close access tf
   else
      display dialog "There are no connected users!"
   end if
end writeUsers
