Please, note that this can be error prone as the script has a unique name: running multiple pipeline at a single time can bring to an error (think of master+develop).

Issue fixed by running a remote chmod command before running the /tmp/shared_links_update.sh script. To do this, I had to add the authorization of this command in the Shell script in charge of filtering the commands executed via SSH (/home/cochise/.ssh/check_ssh_command.sh).
