In python, but let it communicate with a shell script via named pipe or file.
So something like this could work: subprocess.Popen()Īlternatively, consider implementing interprocess communication. Stdout = subprocess.check_output(cmdlist, env=new_env)Īnd here's an example using it in my xrandr-indicator for switching screen resolution from Ubuntu's top panel as the name suggests, it calls xrandr behind the scenes : n_cmd()Īs for shell, you'd need to call a shell with -c argument. """ Reusable function for running external commands """ Here's for example a standard function I use for calling external commands from Python script: def run_cmd(self, cmdlist): You can call commands stored in places like /bin or /usr/bin via subprocess module in Python. It's a scripting language, yet more suitable for system and programming stuff than shells. So the answer is no, you can't use full-blown Gtk stuff in shell scripts, only the limited set of things that yad and zenity allow.īut you can use Python. When you use subprocess, Python is the parent that creates a new child process.
The parent-child relationship of processes is where the sub in the subprocess name comes from. These processes can be anything from GUI applications to the shell.
Gtk is a library, and meant to be imported in actual programming languages. The Python subprocess module is for launching child processes. Shells are just command interpreters as per POSIX definition.
