                            Hello all,<br>
                            <br>
                            I want to run multiline shell command within
                            python without using a command file but
                            directly execute several lines of shell.<br>
                            I already use *subprocess.checkoutput("csh
                            -f my_file.csh".split())* but I want to know
                            if it is posssible to avoid making file and
                            execute<br>
                            shell lines of code directly.<br>

                          <div>Yes, this is very possible. Specify
                            shell=True as an argument and you can do
                            anything you can do in a shell:</div>
                          <div><br>

                          <div>... ps aux | grep python"""</div>
                          <div>>>> b =
                            subprocess.check_output(commands,
                            shell=True)</div>

              Many thanks Hugo. It makes my day!<br>
              In my case there are no possibilities for shell injection.
              It is internal to a class.<br>
