In addition, exec_command takes keyword arguments for (re-)defining environment variables. Provides functions: exec_command --- execute command in a specified directory and in the modified environment. find_executable --- locate a command using info from environment variable PATH. Equivalent to posix `which` command.

Default None (True) use_tee : {bool, None}, optional If True use tee. Default None (True) Returns ------- res : str Both stdout and stderr messages. Notes ----- On NT, DOS systems the returned status is correct for external commands.
