The output of dir is different in command.com and cmd.exe. In a version I
have of cmd.exe compiled for win9x, the following works for me.
function sfn() {
win95cmd /c dir /x "$1" | \
sed -e '/^ /d' \
-e 's/^......................................//' \
-e 's/^ *//' -e 's/ .*//'
}
You might have to play with the options to dir and with the sed processing
to get it to work for Win2k.

This doesn't work under Win2k. First, it doesn't like "command.com". After
changing that to "cmd", it just prints the date when the first was
modified...
