Add a delay in git post-merge

My scenario is as follows: After updating files on my Git repository, I have a Git hook that calls an API from my web server. This API performs a Git pull and then I have a Git hook post-merge that restart the web server (Gunicorn). The restart of the web server should occurs a few seconds after the pull is completed otherwise the web server is shutting down before the API call is completed and that returns an error to the Git hook. Currently I worked out the following solution but I am not happy with it. The file .git/hooks/post-merge #!/bin/sh /var/www/tempcollect/.git/hooks/restart > /var/www/tempcollect/.git/hooks/restart.log & The file .git/hooks/restart sleep 10s /usr/bin/sudo systemctl restart tempcollect I would prefer to have the command to restart the web server in the post-merge file. The execution of the file post-merge is started by Git at the end of the pull, thus I have no control on the way it is started.
