How to execute a file without the ".exe" extension

Question

I have a file: "abc", it's a executable file. I want to execute it by Phthon or windows CMD.

If I write code:

subprocess.Popen('-a -b -c', creationflags=0x08, shell=True, executable="C:\\abc")

Then, abc executed, but params(-a -b -c) been ignored

So...How Can I reslove it?

Have you tried `subprocess.Popen("C://abc -a -b -c", shell=True)`? See https://stackoverflow.com/questions/11284147/how-to-do-multiple-arguments-with-python-popen — ChrisOram, Oct 12 '21 at 08:36
this should work. And the preferred way is using an argument list (and drop shell=True). How can you be sure/prove that the arguments are ignored? for instance this works: `p=subprocess.Popen("/c dir",executable=r"C:\Windows\System32\cmd.exe")` — Jean-François Fabre, Oct 12 '21 at 08:38

Why not change your code to the following version

args = ['C:\\abc', '-a', '-b', '-c']

p = subprocess.Popen(' '.join(args), shell=True, stdout=subprocess.PIPE, stderr=subprocess.STDOUT)

or without shell=True you can further reduce it to

p = subprocess.Popen(args, stdout=subprocess.PIPE, stderr=subprocess.STDOUT)

or you can use another method to get output from your exe and pass arguments to it

Output = subprocess.check_output(' '.join(args), shell=True).decode()

if a executable(c:\\abc) file's name without the ".exe", Popen not work: abc not be called. And when I rename abc to abc.exe, it works – yuriarthas Oct 12 '21 at 09:28

Finally, I found the answer myself, which is to use win32process.CreateProcess Thanks to other authors, but their answers are wrong.

The correct answer is:

win32process.CreateProcess(r"C:\abc", "-a -b -c", None, None, 0, 0, None, None, win32process.STARTUPINFO())

The following answer does not work:

subprocess.Popen('-a -b -c', creationflags=0x08, shell=True, executable="C:\\abc")

#or

p = subprocess.Popen(args, stdout=subprocess.PIPE, stderr=subprocess.STDOUT)

Maybe I really don’t know how to use subprocess, but Windows is really special. Executable files without a suffix cannot be executed directly on the command line.

This is neither python nor CMD nor a way to call without the `exe` extension. – Daniel May 05 '22 at 14:02
