If I have a basic Python script, with it\'s hashbang and what-not in place, so that from the terminal on Linux I can run
/path/to/file/MyScript [args]
The best place to put things like this is /usr/local/bin.
/usr/local/bin
This is the normal place to put custom installed binaries, and should be early in your PATH.
PATH
Simply copy the script there (probably using sudo), and it should work for any user.
sudo
