Hi, it's possible to automate the use of "su" command??
I refer to the issue of the introduction of the password.
There is something like this:
su - username/password???
Thanks.

Re: Automate switch user
You can use "sudo" instad of su. Or maybe a combination of both, for example:
sudo su - user -c "command"
You need to configure the sudoers file with the visudo command.
Check for information about sudo in google.
Cheers.
sudo su - user -c "command"

Combining su and sudo means you're first transitioning to root, and then to target user. The logs will reflect that. Sometimes, seeing a message about JoeUser becoming root can cause undue agitation in security auditors.
If you have a relatively modern version of sudo, the effect of:
sudo su - -c
can be exactly replicated with:
sudo -u -i
It will also consolidate all the essential information into one log line: JoeUser becomes for the purpose of running the .
Of course, to use "sudo -i" effectively, your sudoers file must be written to say what you really mean: instead of
JoeUser ALL=(root) su -
you should write:
JoeUser ALL=() ALL
If you need to allow JoeUser to execute a particular command automatically, without prompting a password, you might write:
JoeUser ALL=() NOPASSWD:
(OK, I admit: this is my pet peeve. But I see "sudo su - ..." as a nothing more than a bad habit, encouraged by sloppy sudoers rule writing practices.)
