    You can download it to a temporary location (using mktemp), then compare the checksums of the existing and downloaded files, and move the file from temporary location to $FILE if the checksum is different. This is not necessary though since docker-compose can tell if the compose file has changed, but it will be helpful to the user to know whether they have downloaded an updated file or not.

      git pull
ansible-playbook -i inventory/hosts lemmy.yml --become
