The builder.sh script builds the different scripts of the Wazuh installation assistant repository:

echo -e "DESCRIPTION"
echo -e "        -i,  --installer"
echo -e "                Builds the installation assistant (wazuh-install.sh)"
echo -e ""
echo -e "        -c,  --cert-tool"
echo -e "                Builds the certificate tool (wazuh-certs-tool.sh)"
echo -e ""
echo -e "        -d [pre-release|staging],  --development"
echo -e "                Use development repositories. By default it uses the pre-release package repository. If staging is specified, it will use that repository."
echo -e ""
echo -e "        -p,  --password-tool"
echo -e "                Builds the password tool (wazuh-passwords-tool.sh)"
echo -e ""
echo -e "        -h,  --help"
echo -e "                Shows help."

I have discovered that, if no parameter is passed to the builder.sh script, the script does not print the help (it does not perform any operation either).

➜  bash builder.sh 
➜   

Important

It would be desirable that, if no argument is passed to this script, the help will be printed, in order to follow the script usage.
