Impossible to execute a command by using su for another (system) user I've created my user like this: `sudo adduser --disabled-password --system --home /var/lib/deluge --gecos "Deluge server" --group deluge` The content of `/etc/passwd`: `deluge:x:110:114:Deluge server,,,:/var/lib/deluge:/bin/false` The directory I'm in : root@xxxxxx:/var/lib/deluge/.flexget# ls -al drwxr-xr-x 2 deluge deluge 4096 15 mars 11:39 . drwxr-xr-x 7 deluge deluge 4096 15 mars 11:40 .. -rwxr-xr-x 1 deluge deluge 3881 15 mars 11:39 config.yml What I'm trying to do : su deluge -c "flexget --test execute" But nothing happens, I've got no error shown, I also tried just `su deluge` but the same still root. How can I run a command using this user ? (I'm not using `sudo`)

Your `deluge` user has `/bin/false` for their default shell - this is what `su` is running and passing the `-c` option to (or running without any options when you simply do `su deluge`). You can use the `--shell` option to `adduser` to set a shell when creating the user. Eg:


sudo adduser --shell /bin/sh --disabled-password --system \
--home /var/lib/deluge --gecos "Deluge server" --group deluge


Or use `chsh` to change the shell for an already created user:


sudo chsh -s /bin/sh deluge


Or you could use the `--shell` (or `-s`) option with `su` to override `/etc/passwd`:


su deluge -s /bin/sh -c "flexget --test execute"


Depending on what else your are doing with the user, `/bin/bash` might be a more appropriate shell to use.
