This file details changes in the U/Win product from version 1.0 to
version 1.1.


New utilities
-------------

The following commands are new to version 1.1:

  cmp    Compare two files on a byte for byte basis (allowing binary files to
         be compared).
  cut    Retrieve selected fields from each line of a text file.
  diff   Compare two text files, showing logical differences (additions,
         changes, deletions).
  du     Reports disk usage by directory.
  find   find files matching a specification (name mask, size, date, etc).
  head   display the beginning of a file.
  mv     move files and directories.
  rm     remove files and directories (including files in subdirectories).
  tail   display the end of a file (supports continuous display option "-f").


Enhancements to existing utilities
----------------------------------

REGULAR EXPRESSIONS

The grep utility now supports regular expressions.  All commands accepting
file names as arguments now allow UNIX-style file name patterns, including
a single * to match any name, and character ranges (e.g. [a-z]) to match a
single character.  DOS file name patterns are still supported (*.* and * are
equivalent).


SORT ALGORITHM

A faster sort algorithm has been implemented.  Sort also now uses global
memory so that larger files may be sorted in memory, without having to use
slower work files on disk.


CLIPBOARD SUPPORT

The Windows clipboard may now be used with U/Win standard input and output.
Use &c as the filename following < to read standard input from the clipboard,
or after > to copy U/Win standard output to the clipboard.


CANCEL DIALOG

A Cancel dialog box has been added to the utilities that typically operate
on multiple files.  By pressing the Cancel button, the operation of the
utility (and any commands following it with pipes) is terminated.  The Cancel
button may be "pressed" with a mouse click, or by pressing the space bar.
The dialog box may be repositioned on the screen, by dragging the dialog title
bar.  The new position is retained for future U/Win sessions.


AUTOMATIC PIPE INSERTION

A pipe symbol is automatically appended to the command line if an additional
utility is added from a dialog box.


SCREEN SAVER COMPATIBILITY

With certain screen savers that blank the mouse cursor, the U/Win hourglass
cursor would sometimes disappear during an operation.  The cursor now remains
visible as an hourglass during lengthy U/Win operations.


Bug fixes
---------

CP *.*

The cp utility no longer includes "." and ".." in its expansion of "*.*".  This
had caused the contents of the parent directory to be included in the copy.


RM DIRECTORY ON NON-CURRENT DRIVE

The rm command now works correctly when removing a directory on a drive other
than the current drive.


DF DEFAULT

When no drive or options are provided, df now reports the space remaining on
the current drive.  In version 1.0, df displayed a title line only.


LONG PATH NAMES

Some utilities improperly shortened long path names with an ellipsis, causing
file reads to fail.  For example, e:\test1\test2\test3\test4\test5\test6\test7\
test8\test9\*.c was represented as e:\...\test5\test6\test7\test8\test9\*.c.
The full, correct path name is now used.


SAVED WINDOW POSITION

When U/Win was terminated while in an iconic state, the window position saved
was that of the icon.  The next U/Win session would begin with the window
positioned at the bottom of the screen.  The correct (open) window position
is now saved when U/Win is terminated as an icon.
