Windows CMD Start and wait for the default application in a batch file -

-

i trying start default application file, wait complete, , continue batch file. problem start, when used below creates command prompt window example.doc in title bar. can use call instead of start, call not wait program finish before going next line. appears start needs have executable name , not work default application system in windows.

any ideas how can make happen without having hardcode windows application in batch file well?

set filename=example.doc start /wait %filename% copy %filename% %filename%.bak

how start default application file, wait completion, continue?

it appears start needs have executable name , not work default application system in windows.

start, when used below creates command prompt window example.doc in title bar

start /wait %filename%

the above command won't work because %filename% used window title instead of command run.

always include title can simple string "my script" or pair of empty quotes ""

according microsoft documentation, title optional, depending on other options chosen can have problems if omitted.

source start

try following command instead:

start "" /wait %filename%

alternative solution using default open command

any ideas how can make happen without having hardcode windows application in batch file well?

one way use assoc , ftype default open command used file execute command.

the following batch file (so no hard coding of windows applications needed).

open.cmd:

@echo off  setlocal enabledelayedexpansion set _file=example.doc rem extension %%a in (%_file%) (   set _ext=%%~xa   ) rem filetype associated extension /f "usebackq tokens=2 delims==" %%b in (`assoc %_ext%`) (   set _assoc=%%b   ) rem open command used files of type filetype /f "usebackq tokens=2 delims==" %%c in (`ftype %_assoc%`) (   set _command=%%c   rem replace %1 in open command filename   set _command=!_command:%%1=%_file%!   ) rem run command , wait finish. start "" /wait %_command% copy %_file% %_file%.bak 1>nul endlocal
