- DoubleDir (DD.EXE) Release 2.0 (4/87)
-
- Functions - Shows two directories side by side, sorted by name.
- * Each directory can be paged (scrolled) separately.
- * They can be printed side by side.
- * Wildcards can be used, exactly like the DOS "dir" command.
- * Various sort orders
- * Indicates matching and differing files
-
- * Alters file attributes
- * Copies files
- * Dumps files
- * Erases files
- * The choice of directories to examine can be changed
- without exiting the program.
- * The directories can be re-read to account for a change
- of disk or file status.
- * Moves files between directories without copying them
- * Renames files
-
- * supports 43-line mode when an EGA card is detected.
- * DOS access without exiting
- * supports color
-
- Purpose - Use to compare directories, as when moving files from floppy
- to floppy (or directory to directory). Allows execution
- of file maintainence tasks without losing sight of the
- directory.
-
- Syntax - dd [d:][\][path][filename] [d:][\][path][filename]
-
- Examples - dd
-
- dd a:*.asm b:*.com
-
- dd a:*.doc c:\mm\mydocs
-
- =============================================================================
-
- GETTING AROUND
-
- Default is to the current directory.
-
- Note that the directory on the left BECOMES the current directory when
- specified. For example:
-
- C:\MYDIR>dd c:\dir1 d:\dir2
-
- will CHANGE the DOS current directory to C:\DIR1.
-
- A reverse video bar on the bottom of screen indicates which directory will
- scroll with the cursor keys. Move the bar using Tab, Left, or Right.
-
- Files with matching entries are marked with "║". Files with the same name
- but differing sizes, dates, times, or attributes are marked with "═".
-
- Hidden and Read-only files are shown by "<" and "■". Cursor keys scroll
- the active directory.
-
- Other keys: Tab, Left, Right change active directory
- F1 Help
- F2 Re-read disks.
- F9 Print both directories, side by side.
- F10 Toggle 43-line display (EGA only)
- Esc exit to DOS
- CR Issue DOS command
-
- ============================================================================
-
- THE MENU
-
- Select a function by pressing the CAPITAL letters of your choice:
- For example:
-
- Attrib COpy ChDir Dump Erase Move Reverse Sort Xdos
-
- means press A for Alter, CO for copy, D for dump, V for reverse, etc.
- Pressing Return will give you a simulated DOS command prompt. Pressing
- Return at that prompt will restore the menu.
-
- ============================================================================
-
- THE FUNCTIONS
-
- GENERAL RULES: When you are asked for a filename, pressing Esc
- cancels the operation. Pressing F3 restores the previous
- entry (like in DOS). So do PgUp and Up-arrow.
-
- * Attrib will change the attribute of a file to Hidden, Readonly, or
- Normal. It will not affect the archive bit. Pressing Return without
- a filename will cancel.
-
- * Dump will give one of four kinds of dumps:
- 1) 'Hex' gives a Hex dump (Ascii on the right side)
-
- 2) 'Ascii' gives a 'raw' Ascii dump. It's like saying
- 'copy filename con /b'. Carriage return and other
- special characters appear as graphics.
-
- 3) 'Strings' shows printable strings only. It will ask you
- how many printable chacters in sequence should be considered
- significant (the default is 2, the maximum is 9).
-
- 4) 'Wordstar' strips the high bit of each character, and then
- shows all printable characters.
-
- Pressing Spacebar during a dump will pause it; then any key
- will resume. Pressing Esc during the dump will terminate it.
-
- * ChDir will prompt you for directory names ('Left side' and
- 'Right side'). If you enter a name, it will read the
- appropriate directory onto the side of the screen specified.
- <CR> alone will leave the currently selected directory
- unchanged. Note that the left side becomes the current
- working directory.
-
- * Copy will prompt you for source and target names. It accepts
- wildcards for source, but NOT for target. DON'T COPY
- A FILE TO ITSELF!! The target defaults to the current (left)
- directory. Pressing Return without a source name will
- cancel.
-
- * Erase will prompt you for a filename to erase. It takes
- wildcards. If you try to erase a Readonly file, you will
- get the message 'Access denied.'
-
- * Move will prompt you 'Source:' and 'Target:'. It will move the
- file(s) you name to a new directory, and/or will rename it
- if you wish. Example:
-
- Source: \foo2\*.* Target: \foofiles
-
- or
-
- Source: \ribbet.doc Target: \foofiles\ribbet.txt
-
- * Sort gives five sort options: Date, Extension, Name, Size, and
- Unsort. Extension is sorted first by extension and then
- by Name. The default is Name, ascending order (see Reverse).
-
- * Reverse inverts the current sorting sequence. It works with all
- sort forms.
-
- * Xdos runs COMMAND.COM and clears the screen. To return to
- DoubleDir, issue the EXIT command. DoubleDir will take
- up less than 9k of memory.
-
- * Help (F1) will show the help screen (really just a quick intro
- for those who haven't yet read this manual).
-
- * Re-read (F2) will reread the currently specified directories.
- This allows you to change disks. It is also useful when
- you have asked for a file to be deleted, or an attribute
- changed, as the display is not automatically updated after
- those operations.
-
- * Print (F9) prints the two directories side by side, just as they
- appear on the screen.
-
- * F10 toggles 43-line mode when an EGA is present.
-
- ============================================================================
-
- POSSIBLE CONFUSION
-
- You can specify related directories like in DOS:
-
- [ dd *.* ..\*.* ] will show the current directory and its parent.
- If you CHANGE the left directory [CD], but not the right one, you
- may get a surprise when you press F2 (Re-read), because the right
- directory will show the parent of the NEW current directory. If
- the current directory is the root, you will get the message 'File
- not found'.
-
- ============================================================================
-
- TRICKS AND TIPS
-
- 1) 'Dump Strings' is mostly intended for finding error messages and
- such in compiled code. You can Dump a text file by selecting
- 'Strings', and letting it default to 2 significant chars: it goes
- much faster than the DOS 'type' command.
-
- 2) A common use of the Re-read (F2) function is when looking for a
- file on a group of diskettes. For example, to find the
- files FOO*.DOC:
-
- Type: CD
- Response: 'Left Side: ' Type: c:foo*.doc<CR>
- Response: 'Right Side: ' Type: a:foo*.doc<CR>
-
- Now just keep replacing floppies, hitting F2 each time.
-
- ============================================================================
-
- QUIRKS
-
- 1) The program requires DOS >= 2.0, but does not check.
-
- 2) 'Alter' resets the System attribute when making a System file 'Normal'.
- This does not interfere with any known DOS function.
-
- 3) The 'Dump Wordstar' function sometimes splits lines.
-
- 4) Don't copy a file to itself!
