Therefore, the usage for these commands is as + +```zsh + bench COMMAND [ARGS]... +``` + +### The usual commands + + - **init**: Initialize a new bench instance in the specified path. This sets up a complete bench folder with an `apps` folder which contains all the Frappe apps available in the current bench, `sites` folder that stores all site data seperated by individual site folders, `config` folder that contains your redis, NGINX and supervisor configuration files. The `env` folder consists of all python dependencies the current bench and installed Frappe applications have. + - **restart**: Restart web, supervisor, systemd processes units. Used in production setup. + - **update**: Updates bench tool and if executed in a bench directory, without any flags will backup, pull, setup requirements, build, run patches and restart bench.
