If preexec_fn is set to a callable object, this object will be called in the child process just before the child is executed. (Unix only) If close_fds is true, all file If passing a single string, either shell must be True (see below) or else the string must simply name the program to be executed without specifying any arguments. Note that on Windows, you cannot set close_fds to true and also redirect the standard handles by setting stdin, stdout or stderr.

The arguments shown above are merely the most common ones, described below in Frequently Used Arguments (hence the slightly odd notation in the abbreviated signature). his comment is here What can I do to prevent this in the future?

In addition, the replacements using check_output() will fail with a CalledProcessError if the requested operation produces a non-zero return code. If env is not None, it must be a mapping that defines the environment variables for the new process; these are used instead of inheriting the current process' environment, which non_existent; rm -rf / # >>> call("cat " + filename, shell=True) # Uh-oh.
