When writing a Python code, I could write os.system('some cmd command'). How could I make it run from a specific directory (without using a 'cd' command)?
The reason I'm trying to do this is because my cmd command isn't in my cmd PATH, and therefore is recognized only in its own directory.
I'm looking for something similar to this:
p = Popen ('file.bat', cwd = 'location')
stdout, stderr = p.communicate()
just without having to create a .bat file for it...
You could always do:
p = Popen ('../relative/path/to/executable.exe')
stdout, stderr = p.communicate()
Or you could hard-code an absolute path in there, but be sure to check if the file exists first or to catch any exceptions thrown by the popen calls (more pythonic).
LE:
Please note that there is a cwd parameter on the Popen's constructor, but the executed program's current directory will be changed to that, it won't look for the executable in there.
shell=True as another argument for the Popen constructor. Be sure to read on why that might be a security issue if the command you're running comes from user input in the documentation of the subprocess module.shell=True is needed only if the command is to be passed through the shell, from your original question I understand that your command is an executable script, which shouldn't require that, though this is only an assumption.
