This seems massively complicated for a simple shell command to send an email. ON top of that you are attempting to break the anisble.builtin.script module by forcing it to run on the localhost (controller) rather than the target. Better option would be to just use the either the command module and mailx or the community.general.mail.module, both options will run fine with the "delegate_to: localhost" and require much less coding to make work.
A rough example base on the visible code: name: mail host list community.general.mail: host: mail.server.com port: 25 to: John Smith <[email protected]> from: [email protected] subject: Ansible-report body: List of hosts {{ ansible_hostname }} delegate to local hostocalhost register: out vars: arg: "{{ ansible_play_hosts_all | join(' ') }}" On Fri, Jul 28, 2023 at 9:46 AM Prady A <[email protected]> wrote: > Hi Todd, > > Thank you so much as always. > Actually to run the ansible we switch from normal user to root user and > run the ansible. > In my case when I m running "who am i" from Putty it is working but when > I am executing it from visual studio code using remote ssh login plugin > there it is not working. > Basically I want to send the mail from the user who logged in ex: > [email protected].
