File Manager Commands
=====================

Prompt
------

The prompt character, which is displayed when the File Manager is ready
to receive a command, is the greater than sign '>'. If this is not
displayed, then no input is expected.

Command Syntax
--------------

Commands are typed in with their arguments (usually filenames) separated
by spaces. Wildcard characters may be specified. Commands may be in
upper or lower case alphabetic characters.

Wildcards
---------

DEMOS supports the use of wildcards '?' and '*'. The '?' character will
allow DEMOS to search file names and disregard the characters replaced
with '?'. For example, suppose there where five files with the names
FILE1.TXT - FILE5.TXT. The following :doc:`dir` command would only
list those files:

::

   >DIR FILE?.TXT
   FILE1.TXT FILE2.TXT FILE3.TXT
   FILE4.TXT FILE5.TXT

or

::

   >DIR A?FILE.COM
   AAFILE.COM ACFILE.COM A4FILE.COM

The '*' wildcard replaces the entire extension or file name. The example
below will list all files with the extension .HBA:

::

   >DIR *.HBA
   PROG1.HBA PROG2.HBA START.HBA

or

::

   >DIR MYFILE.*
   MYFILE.TXT MYFILE.COM MYFILE.HBA

To list all files held in the HUNTER the command 'DIR' is used.

A combination of wildcards can also be used:

::

   >DIR ??FILE.*
   MYFILE.TXT MYFILE.CCM MYFILE.HBA
   AAFILE.CGM ACFILE.COM A4FILE.COM
   MRFILE.HBA

Wildcards may be used with other File Manager commands apart from
:doc:`dir`, for instance, as follows with the :doc:`era` command:

::

   >ERA BIG.*

this will erase any file starting with 'BIG' and any extension for
example, BIGER.FIL, BIG.HBA or BIGGLES.COM would all be deleted.

Note that, as a precaution. Hunter will query the erasure of each file
in turn, requiring operator confirmation at each stage.
