问题
I am at beginner level and I need to use sudo su - and pwd in one command line in script for two different users. (I'm using pwd as an example; the specific command is not important.)
And I am using command sudo su - user -c pwd. This command works when switching to one user, but not when switching to another.
For example:-
$ sudo su - ora -c pwd
/oracle/
$ sudo su - adm -c pwd
Sorry, user myuser is not allowed to execute '/usr/bin/su - adm -c pwd' as root on server.
$
How can I make it work for 'adm' user too?
回答1:
sudo is used to run a command as somebody else. By default it runs a command as root. You can also supply the -u option to run a command as another user. You really shouldn't need to use sudo and su together as they do similar jobs. Sudo does this job in a much more controlled and configurable fashion.
Sudo can be configured to control:
- Who can use it.
- What commands they can run.
- Who they can run them as.
- Whether they need to supply their password when doing so.
You can only run one command at a time, so if you need to do several things together you will need to write a script. Alternatively you can chain them together in a one liner. Or finally you can run a shell as the user you require. e.g.:
sudo bash
I think in your case you probably want to use:
sudo -u adm anycommand
