I apologize if this isn't an strictly an ansible problem, but I'm
attempting to run a command like the following which works when run

Shell in Ansible is using /bin/sh, depending on your distribution sh
usually has limited functionality. So things like [[ ]] and $() might
not work.
The full explanation of what i'm trying to do is create a log with the
history of ansible plays run and their version in git that have been run
against the target application. In the full script the commit hash will be
coming from a register variable in a previous step, but i can't even get a
basic case to run with all the competing special characters. The command is
supposed to look at a log file and compare the last entry to the current
entry to be written and if they're not the same, to add the entry to the
end of the file. I tried doing this more simply with lineinfile but it
would only write if the line didn't exist somewhere else in the file(which
is not what i want).
Thanks in advance for any advice/help given.
There is a few ways to solve it, make script or do something like this:
- name: Get last log
command: tail -1 /app/psoft/install_logs/deployment_version_history.log
register: mylog
- name: Update log
shell: echo "81cdc80ec7fdb0201e00fe2f8767b10ec136c687 peoplesoft.yml"
>> /app/psoft/install_logs/deployment_version_history.log
when: mylog.stdout != "81cdc80ec7fdb0201e00fe2f8767b10ec136c687
peoplesoft.yml"
