subprocess.Popen(): OSError: [Errno 8] Exec format error in python?

Question

Yesterday, I wrote and ran a python script which executes a shell using subprocess.Popen(command.split()) where command is string whic

Answer 1

The error is because the executables are not given in the prescribed format for subprocess to execute it.

example:

shell_command1 = r"/path/to/executable/shell/file"

shell_command2 = r"./path/to/executable/shell/file"

subprocess.call(shell_command1) or subprocess.Popen(shell_command1) will not be able to run shell_command1 because subprocess needs an executable command like (mailx, ls, ping, etc.) or executable script like shell_command2 or you need to specify command like this

subprocess.call(["sh", shell_command1])
subprocess.Popen(["sh", shell_command1])

but however, you can use os.system() or os.Popen() as well
