py-admin-launch 0.1.3

A cross-platform command launcher for administrator privileges.

py-admin-launch

A cross-platform Python command/helper to launch a specified program with administrator privileges.

Strategy

• Linux desktop: pkexec for polkit GUI authentication, falling back to sudo when pkexec is not available. GUI session variables such as DISPLAY, XAUTHORITY, WAYLAND_DISPLAY, XDG_RUNTIME_DIR, and DBUS_SESSION_BUS_ADDRESS are passed explicitly so desktop apps can still reach the current display after elevation.
• Windows: ShellExecuteW(..., "runas", ...).
• macOS: osascript + with administrator privileges, falling back to sudo when osascript is not available.

If the current process is already administrator/root, the command is launched directly as the current user.

CLI

Run from source:

python -m py_admin_launch -- your-command arg1 arg2

After installing the package:

py-admin-launch -- your-command arg1 arg2

Useful options:

py-admin-launch --cwd /path/to/workdir -- your-command arg1 arg2
py-admin-launch --no-wait -- your-command arg1 arg2

The CLI waits by default. On Linux and macOS, that means py-admin-launch returns the elevated command's exit code, including failures such as cancelled authentication or a failed pkexec/sudo invocation. This matches the behavior users usually expect from commands like sudo your-command.

Use --no-wait only when you intentionally want to start the command in the background and return after the elevation request is handed off. In that mode, the launcher cannot report the elevated command's later exit code.

On Windows, elevated launches use ShellExecuteW(..., "runas", ...), which does not provide a child process handle to this helper. That means the CLI cannot observe the elevated program's exit code on Windows.

Python API

from py_admin_launch import launch

launch(["python", "-m", "http.server", "80"])

launch() accepts a command list plus optional cwd and wait arguments:

result = launch(["your-command", "arg1"], cwd="/tmp", wait=True)
print(result.elevated, result.returncode)

When wait=True, returncode is the launched command's exit code where the platform exposes one. When wait=False, returncode is None.
