Hello!

I have tried various ways to get my output to email in a readable format, with newlines, but ansible strips them off everytime. Its just a few shell commands i am testing. I've tried a for loop, with items, replace, etc. My email output is all on one-line like so:

"- ' 12:23:27 up 64 days, 1:36, 2 users, load average: 0.21, 0.08, 0.02' - USER TTY FROM LOGIN@ IDLE JCPU PCPU WHAT - 'dbsxxx pts/0 ho-it-dbsxxx-dt Tue08 19:39m 0.16s 0.30s sshd: dbsxxxx [priv]' - root pts/1 ho-lx-ansible01. 12:23 0.00s 0.10s 0.00s /usr/bin/w - Filesystem Size Used Avail Use% Mounted on - devtmpfs 11G 0 11G 0% /dev - tmpfs 11G 0 11G 0% /dev/shm - tmpfs 11G 1.1G 9.1G 11% /run - tmpfs 11G 0 11G 0% /sys/fs/cgroup - /dev/mapper/rootvg-root 46G 28G 19G 61% / - /dev/mapper/rootvg-home 10G 33M 10G 1% /home - /dev/sda1 1.1G 383M 656M 37% /boot - /dev/mapper/satvg-satlv01 503G 408G 96G 82% /var/satellite - /dev/mapper/oravg-oralv01 142G 41G 102G 29% /opt/oracle - tmpfs 2.1G 0 2.1G 0% /run/user/0 - tmpfs 2.1G 0 2.1G 0% /run/user/1922732921 "

my yaml code is:

- name: DF + UPTIME PLAYBOOK
hosts: "*"
gather_facts: false

tasks:
- shell: |
/usr/bin/w
/usr/bin/df -h
register: dfu

- debug: var=dfu.stdout_lines

- name: mail result
community.general.mail:

host: internal-smtp.xxxxxx.com
subtype: html
to: 'dbs...@xxxxxx.com'
subject: test
body: <h3> "{{ dfu.stdout_lines | to_nice_yaml(indent=4) }}" </h3>
...

How do I tell ansible to output in a email format like the way I see it from the debug output on my screen?

The console is using a fixed width font, while your mail client is not.

You need to format the email body in a way that your mail client uses a fixed width font to display it. This is not something this list is for, but as a start wrap the output in <pre> tags instead of <h3>.

Google for email formatting and html to tweak things further.
