The contents of the power_consumption.sh script are -
hostfqdn=$(hostname --fqdn)
time=1
declare T0=($(cat /sys/class/powercap/intel-rapl/*/energy_uj));
sleep $time; declare T1=($(cat
/sys/class/powercap/intel-rapl/*/energy_uj))
for i in "${!T0[@]}"; do echo - | awk "{printf \"%.1f W\",
$((${T1[i]}-${T0[i]})) / $time / 1e6 }" >> $hostfqdn.txt ; done
I have no idea what I am doing wrong, I have tried to put the
script in /usr/bin as well but same result for all tasks -

Hi,
This if often because your ’shell’ script has the incorrect
shebang at the top. If its a bash script then add executable:
/bin/bash and try again, or check your script.
Cheers.

I also create a simple foo.sh and tried to execute it like
this, but here also I get errors -
foo.sh contents -
#!/bin/sh
echo "Hello world"
My TestShell script yml looks like this -
- name: Shell script test
hosts: all
tasks:
- name: Run a shell command and register its output as
a variable
ansible.builtin.shell: /usr/src/foo.sh
register: foo_result
ignore_errors: true
- name: Run a shell command using output of the
previous task
ansible.builtin.shell: /usr/src/bar.sh
when: foo_result.rc == 5
Output of the above yml gives this error -
