Hi, I need to execute an external command with Python from Web. I know there is subprocess module that executes external programs but I'm trying to execute a command registered for the execution of a program. In this case when I execute my file in the shell everything is Ok, but from the Web it doesn't work. Does anybody know what could be???

Hi. I don't know much Python, but it's usually permissions. It could other things, like $PATH, $DISPLAY, current directory, selinux, etc. Working on getting the error message is often the easiest way. Does the program write anything to stderr? What is the python code doing with errors?
