I work on redhat and i can't find odoo-bin file it not exist in my odoo folder. I have command not found

To create a new custom module try the below command:

./odoo-bin scaffold custom_module_name addons_path

In ubuntu you can find "odoo-bin" in "/opt/odoo10/odoo". Since 'odoo-bin' is a hidden file you must enable the "Show hidden files" from the 'view' menu.
