VMS Help  —  EDIT  /ACL
    The access control list editor (ACL editor) creates or modifies
    an access control list (ACL) for a specified object.

    Format

      EDIT/ACL  object-spec

1  –  Parameter

 object-spec

    Specifies the object whose access control list is to be created
    or edited. If an access control list does not exist, it is
    created.

    You can specify an object from any of the following object
    classes:

       Capability
       Common event flag cluster
       Device
       File
       Group global section
       Logical name table
       Queue
       Resource domain
       Security class
       System global section
       Volume

    The default object class is a file. A file must be a disk file
    on a Files-11 On-Disk Structure Level 2 formatted volume. For any
    object other than a file, you must specify the object class with
    the /CLASS qualifier.

    Note that the ACL editor does not provide a default file type
    for files. To prevent the ACL editor from using a null file type,
    specify the file type on the command line. If the object is a
    directory, specify the .DIR file type.

    Do not include wildcard characters in the object specification.

1.1  –  Qualifiers

    Qualifier      Description

    /CLASS         Specifies the class of object whose ACL is being
                   edited
    /JOURNAL       Controls whether a journal file is created for the
                   editing session
    /MODE          Specifies the use of prompting during the editing
                   session
    /OBJECT_TYPE   Superseded by the /CLASS qualifier
    /RECOVER       Restores an ACL from a journal file at the
                   beginning of an editing session

2    /CLASS

    Specifies the class of the object whose ACL is being edited.
    Unless the object is a file, you must specify the object class.

    Format

      /CLASS  =object-class

2.1  –  Description

    To edit the ACL for an object other than a file, specify the
    object class with the /CLASS qualifier. Specify one of the
    following classes:

    CAPABILITY           A system capability, such as the ability to
                         process vector instructions. Currently, the
                         only defined object name for the CAPABILITY
                         class is VECTOR, which governs the ability
                         of a subject to access a vector processor
                         on the system. Note that you must supply
                         the capability name as the object name
                         parameter.
    COMMON_EVENT_        A common event flag cluster.
    CLUSTER
    DEVICE               A device, such as a disk or tape drive.
    FILE                 A file or a directory file. This is the
                         default.
    GROUP_GLOBAL_        A group global section.
    SECTION
    LOGICAL_NAME_TABLE   A logical name table.
    QUEUE                A batch queue or a device (printer, server,
                         or terminal) queue.
    RESOURCE_DOMAIN      A resource domain.
    SECURITY_CLASS       A security class.
    SYSTEM_GLOBAL_       A system global section.
    SECTION
    VOLUME               A disk or tape volume.

2.2  –  Examples

    1.$ EDIT/ACL/CLASS=DEVICE WORK1

      The command in this example specifies that the object WORK1 is
      a device.

    2.$ EDIT/ACL/CLASS=QUEUE FAST_BATCH

      The command in this example creates an ACL for the queue FAST_
      BATCH. Note that if you create an ACL for a generic queue, you
      must create identical ACLs for all execution queues to which
      jobs can be directed.

3    /JOURNAL

    Controls whether a journal file is created for the editing
    session.

    Format

      /JOURNAL  [=file-spec]

      /NOJOURNAL

3.1  –  Description

    By default, the ACL editor keeps a journal file containing a
    copy of modifications made during an editing session. The journal
    file is given the name of the object and a .TJL file type. If
    you specify a different name for the file, do not include any
    wildcard characters.

    To prevent the ACL editor from creating a journal file, specify
    /NOJOURNAL.

    If your editing session ends abnormally, you can recover the
    changes made during the aborted session by invoking the ACL
    editor with the /RECOVER qualifier.

3.2  –  Example

  $ EDIT/ACL/JOURNAL=COMMONACL.SAV MECH1117.DAT

      With this command, you create a journal file named
      COMMONACL.SAV. The file contains a copy of the ACL and
      the editing commands used to create the ACL for the file
      MECH1117.DAT.

      If the editing session is interrupted, you can recover your
      edits by specifying the name COMMONACL.SAV with the /RECOVER
      qualifier.

  $ EDIT/ACL/CLASS=RESOURCE/JOURNAL=ZERO_RESOURCE.TJL [0]

      If you edit an ACL for the resource domain [0], the ACL editor
      attempts to create the file [0].TJL on the default device
      and fails. To create an ACL for the resource [0], you must
      specify a different name for the journal file (as shown in this
      example) or suppress the creation of a journal file with the
      /NOJOURNAL qualifier.

4    /MODE

    Specifies the use of prompting during the editing session.

    Format

      /MODE  =option

4.1  –  Description

    By default, the ACL editor prompts you for each ACE and provides
    values for some of the fields within an ACE (/MODE=PROMPT). To
    disable prompting, specify /MODE=NOPROMPT on the command line.

4.2  –  Example

  $ EDIT/ACL/MODE=NOPROMPT WEATHERTBL.DAT

      With this command, you initiate an ACL editing session to
      create an ACL for the file WEATHERTBL.DAT. The /MODE=NOPROMPT
      qualifier specifies that no assistance is required in entering
      the ACL entries.

5    /OBJECT_TYPE

    The /OBJECT_TYPE qualifier is superseded by the /CLASS qualifier.

6    /RECOVER

    Restores an ACL from a journal file at the beginning of an
    editing session.

    Format

      /RECOVER  [=file-spec]

      /NORECOVER

6.1  –  Description

    The /RECOVER qualifier specifies that the ACL editor must restore
    the ACL from a journal file. The ACL editor restores the ACL
    to the state it was in when the last ACL editing session ended
    abnormally.

    By default the journal file is given the name of the object and
    a .TJL file type. If you specify a more meaningful name for the
    journal file when you invoke the ACL editor (by using /JOURNAL),
    specify that file name with the /RECOVER qualifier.

6.2  –  Example

  $ EDIT/ACL/JOURNAL=SAVEACL MYFILE.DAT
     .
     .
     .
  User creates ACL until system crashes
     .
     .
     .
  $ EDIT/ACL/JOURNAL=SAVEACL/RECOVER=SAVEACL MYFILE.DAT

     .
     .
     .
  ACL is restored and user proceeds with editing until done
     .
     .
     .
    ^Z
  $

      The first command in this example starts the ACL editing
      session and specifies that the ACL editor must save the journal
      file SAVEACL.TJL if the session ends abnormally. The session
      proceeds until it is aborted by a system crash.

      The next command restores the lost session with the journal
      file SAVEACL.TJL. To end the session, press Ctrl/Z. The ACL
      editor saves the edits and deletes the journal file.
