Synopsis:
   The CD command changes the current "working directory".
Syntax:
   CD [path/]<dirname>
Description:
   If [path] is omitted, the target <dirname> is interpreted relative
   to the current working directory. Forward (/) and backward (\)
   slashes may be used interchangeably. Pathnames are case-sensitive.
Examples:
   CD FRED       Change to subdirectory FRED of current directory
   CD ..         Change up one level to parent directory
   CD /          Change to root directory
   CD FRED\JIM   Change to JIM subdirectory of FRED directory.
   CD ..\docs    Change up to parent, and down to 'docs' subdir.

   CDUP   Change up one directory

Synopsis:
   CDUP -- Change to 'parent' directory.
Syntax:
   CDUP
Description:
   The CDUP command changes the current working directory up one level
   to the parent directory, i.e. it performs the function of "CWD .."
   This command takes no arguments, and if the current directory is
   the root directory, CDUP has no effect.

Synopsis:
   COPY -- Copy or create file(s)
Syntax:
   COPY <source> [dest]
Description:
   The COPY command copies the file(s) specified by the pathname
   <source> into the file(s) or directory specified by [dest].
   <source> may be a directory, a single file, or multiple files
   specified using wildcards, and may contain a drive and path spec.
   If <source> is a directory, all the files in that directory are
   copied. If <source> contains wildcards, all matching files are
   copied. If <source> is "CON" (console) any further input from the
   keyboard goes into the file until receipt of Ctrl-Z or /EX on a
   fresh line.
   [dest] may be a directory, a single file, or blank. If [dest] is a
   directory, the source file(s) are copied into it as seperate files.
   If [dest] is a single file, the source file(s) are concatenated
   into it. If [dest] is not specified, the file is copied into the
   working directory, and retains the original filename. 
Examples:
   COPY ..\MYPROG.EXE  /progs/TESTPROG.EXE  
   COPY xrpi-backup/FWD.SYS                      
   COPY *.HLP HELP.DOC
   COPY CON fred.txt
Limitations:
   Concatenation using the "+" operator is not supported.
   Destination files are overwritten without warning.

Synopsis:
   The DEL (delete) command deletes one or more files.
Syntax:
   DEL <filespec>
Description:
   <filespec> may describe either an absolute or relative path
   and/or filename. Forward (/) and backward (\) slashes may be used
   interchangeably. Pathnames are case-sensitive.
   If <filespec> contains wildcards ('*' and '?'), any matching file
   is deleted.
Examples:
   DEL JIM.TXT         Delete file JIM.TXT from current directory.
   DEL \FRED/DOG.EXE   Delete DOG.EXE from directory /FRED
   DEL ../*.LOG        Delete all log files in parent directory.
Caveats:
   There is no "are you sure" warning.

Synopsis:
   DF -- Display free space on disk
Syntax:
   DF
Description:
   The DF command displays the free and total space in bytes on the
   drive containing XRouter, plus sector and cluster size information.

   disk drive.
Caveats:

Synopsis:
   DIR -- List files in a directory
Syntax:
    DIR [path/][mask]
Description
    The DIR command lists the contents of the specified directory, in
    alphabetical order, using the optional specified mask.
    If [path] is not specified, the "current working directory" is
    assumed. Forward and back slashes can be freely mixed. If [mask]
    is not specified, "*.*" is assumed. If only the filename part is
    specified, the extension ".*" is assumed.
Examples
    DIR MSGHDR??.*
    dir LOG\
    DIR /pub\DOCS\*.txt
Limitations
    Does not at present accept pipes, redirection or switches

Line Editor Commands:
    In the following document, n1, n2 and n3 refer to line numbers.
    These must be greater than zero, and within the range of line
    numbers used in the file being edited. The space between the
    command and the first number may be omitted. The numbers may be
    separated by spaces, commas, colons, tabs etc. Parameters in square
    brackets [] are optional. When copying, moving or inserting lines,
    the "source" text is inserted at the "destination" line, i.e.
    "in front of" the original text. Commmands are not case sensitive.
? -- Displays a brief list of commands
A <text> -- Append line <text> to the file
    The editor ignores exactly one space between the A and the text
    to be inserted. If you want to enter a line which has leading
    spaces, add one extra space.
C n1 n2 [n3] -- Copy line(s)
    If n3 is omitted, line n1 is copied into line n2, otherwise the
    block n1 to n2 inclusive is copied into the position beginning at
    n3. Note: n3 must not be within the block being copied.
D n1 [n2] -- Delete line(s)
    If both n1 and n2 are specified, the block of lines between and
    including n1 and n2 will be deleted. If n2 is omitted, or is the
    same as n1, only n1 will be deleted.
H n1 -- Hash (comment-out) a line using the '#' symbol
    This is useful for disabling configuration entries without
    deleting them. They can be easily re-activated at a later date
    using the U)nhash command. If the line already begins with '#'
    another one is not prepended.
I n1 <text> -- Insert <text> into line n1
L n1 [n2] -- List (display) line(s)
    If n2 is specified, lines n1 to n2 inclusive are displayed,
    otherwise it displays 10 lines beginning at n1. If n1 is omitted,
    it re-displays the same page, or if this is the first time the
    command has been used, the first 10 lines of text are displayed.
M n1 n2 [n3] -- Move line(s)
    If n3 is specified, the block of lines n1 to n2 inclusive are
    moved to the position beginning at n3, otherwise the single line
    n1 is moved to the n2 position.
N -- Next page
    Displays the next page (10 lines) of text.
P -- Previous page
    Displays the previous page (10 lines) of text.
Q -- Quit
    The text is abandoned and the original file is left intact,
    providing you hadn't used the W command.
S -- Save the text.
    Syntax and function identical to W)rite.
U n1 -- Unhash line n1
    Removes a '#' symbol from start of line, if one is present
    (opposite of H)ash).
W [<file>] -- Write (save) file being edited to disk
    If <file> is specified, the work is written there instead of
    the original name, but will not overwrite an existing file.
W! <file> -- Write unconditionally.
    Writes the text being edited to <file>, overwriting any existing
    file of the same name.
WQ -- Write & Quit.
    Writes the modified text back to the original file and quits
    editor. (Same as ZZ)
ZZ -- Same as WQ (see above)

Synopsis:
   EDIT -- Edit a file using line editor
Syntax:
   E[dit] [path/]<filename>
Description:
   The EDIT command is used to create, view or edit text files. It uses
   a line-based text editor which is primarily of use to remote sysops.
   If the specified file doesn't exist, it is created. All editing is
   done in memory, and the original file is only created or modified
   when the sysop issues a write command. 
Examples:
   EDIT ../Stuff\Docs/Xrpi.txt
   EDIT XROUTER.CFG
   edit help/chat.hlp
