Unattended setup succeeding but not really

[Matthew Adams <matthew@matthewadams.me>]

Hi all,

I posted question
http://superuser.com/questions/1031675/why-is-this-dos-batch-file-that-installs-cygwin-unattended-failing
on superuser.com, then realized I should've asked on this first.  The
text of the question is copied below (in case you don't want to head
over to superuser.com).  Any advice?


After assembling information from all over the Internet, I've managed
to come up with a DOS batch script that should be working AFAICT, but
after the Cygwin setup executable finishes (seemingly successfully),
there is no bin directory in the Cygwin root folder.

Why is it failing? Fixes welcome! :)

NB: It attempts to cleanly install in a directory called cyg64 in the
current user's home directory.

setlocal

if exist %HOMEDRIVE%%HOMEPATH%\cyg64 rmdir /s /q %HOMEDRIVE%%HOMEPATH%\cyg64
mkdir %HOMEDRIVE%%HOMEPATH%\cyg64

set CYGSETUP=%HOMEDRIVE%%HOMEPATH%\cyg64\cygsetup64.exe

for /f "tokens=4-7 delims=[.] " %%i in ('ver') do (if %%i==Version
(set v=%%j.%%k) else (set v=%%i.%%j))
if %v%==6.1 (
  bitsadmin /transfer "CygwinDownload"
https://www.cygwin.com/setup-x86_64.exe %CYGSETUP%
) else (
  powershell -command "& { iwr https://www.cygwin.com/setup-x86_64.exe
-OutFile $env:CYGSETUP } "
)

%CYGSETUP% -D -q -R %HOMEDRIVE%%HOMEPATH%\cyg64 -a x86_64 -l
%HOMEDRIVE%%HOMEPATH%\cyg64 -s http://cygwin.mirror.constant.com -P
openssh,autossh,nano,vim,git

endlocal

TIA,
Matthew
