Ansible Simulate "Press Enter" for shell script - ansible

Question

I am trying to run this script:
/usr/share/postgresql-common/pgdg/apt.postgresql.org.sh
When I run it without Ansible I get this:
This script will enable the PostgreSQL APT repository on apt.postgresql.org on
your system. The distribution codename used will be focal-pgdg.
Press Enter to continue, or Ctrl-C to abort.
I tried this and some other variations on this.
- name: 2) Run the PostgreSQL repository setup script
become: yes
expect:
command: /usr/share/postgresql-common/pgdg/apt.postgresql.org.sh
responses:
Question:
- This script will enable the PostgreSQL APT repository on apt.postgresql.org on
- your system. The distribution codename used will be focal-pgdg.
-
- Press Enter to continue, or Ctrl-C to abort.: echo -e '\n\n'
timeout: 30

"This script will enable the PostgreSQL APT repository on apt.postgresql.org on",
"your system. The distribution codename used will be focal-pgdg.",

]
}
The script itself has
if [ -z "${YES:-}" ]; then
echo -n "Press Enter to continue, or Ctrl-C to abort."
read enter
echo
fi
I was thinking of modifying the original script.
Any suggestions?
Thank you in advance.

If you look at that /usr/share/postgresql-common/pgdg/apt.postgresql.org.sh script, you'll see at the beginning:
while getopts "c:f:h:ipstv:y" opt ; do
case $opt in
c) COMPONENTS="main $OPTARG" ;; # make these extra components available
f) SOURCESLIST=$OPTARG ;; # sources.list filename to write to
h) HOST="$OPTARG" ;; # hostname to use in sources.list
i) INSTALL="yes" ;; # install packages for version given with -v
p) PURGE="yes" ;; # purge existing postgresql packages
s) DEB_SRC="deb-src" ;; # include source repository as well
t) PGDG="pgdg-testing" ;; # use *-pgdg or *-pgdg-testing
v) PGVERSION="$OPTARG" ;; # set up sources.list to use this version (useful for beta/devel packages)
y) ;; # don't ask for confirmation
*) exit 5 ;;
esac
YES="yes" # don't ask for confirmation if any option is given
done
This tells us (explicitly, via the comment) that the script won't prompt if you specify any command line options:
- name: install postgres
command: /usr/share/postgresql-common/pgdg/apt.postgresql.org.sh -i -v 14
Furthermore, based on the code you show in your question, you could just set the YES environment variable to a non-empty value to suppress prompting:
- name: install postgres
environment:
YES: yes
command: /usr/share/postgresql-common/pgdg/apt.postgresql.org.sh

pause module has the same behavior.
