WHAT'S MISSING
- Command-line qualifiers for most builtin commands
- Wildcards and relative paths in COPY, MOVE and RENAME
- Set functionality in DATE, TIME, ATTRIB, LABEL
- Full internationalisation of the text (and commands?).
@ -26,11 +25,6 @@ US date-time format is used. Set eg "LANG=en_GB" for DD/MM/YY dates and 24-hour
times.
- Line editing and command recall doesn't work due to missing functionality in
Wine.
- DIR/S only works if no file specification is given, ie "DIR C:\TEMP /S" works
but "DIR C:\TEMP\*.C" doesn't work if a matching file exists in a lower
directory.
- Copy, rename, move, need the source and destination to be specified fully
with an absolute or relative path but no wildcards or partial filenames.
- Redirection is implemented as a command line is parsed. This means that ">"
and "<" symbols cannot appear in command arguments even within quotes.
- In many cases parsing and syntax checking is less rigorous than DOS. Thus an

a GUI such as KDE, however it is not possible to invoke a second shell using the
"CMD /C filename" syntax. Conversely a Win32 application can be invoked from a
Win32 GUI such as Program Manager but that needs starting under Wine first.
