 The `serve` command supports the following flags:
 
-- `--config-dir` string. Location of the config dir. This directory is used as the base for files with a relative path, eg. the private keys for the SFTP server or the SQLite database if you use SQLite as data provider. The configuration file, if not explicitly set, is looked for in this dir. We support reading from JSON, TOML, YAML, HCL, envfile and Java properties config files. The default config file name is `sftpgo` and therefore `sftpgo.json`, `sftpgo.yaml` and so on are searched. The default value is the working directory (".") or the value of `SFTPGO_CONFIG_DIR` environment variable.

The specified file name must have a supported extension (JSON, YAML, TOML, HCL or Java properties). The default value is empty or the value of `SFTPGO_CONFIG_FILE` environment variable.
 - `--grace-time`, integer. Graceful shutdown is an option to initiate a shutdown without abrupt cancellation of the currently ongoing client-initiated transfer sessions. This grace time defines the number of seconds allowed for existing transfers to get completed before shutting down. 0 means disabled. The default value is `0` or the value of `SFTPGO_GRACE_TIME` environment variable. A graceful shutdown is triggered by an interrupt signal or by a service `stop` request on Windows, if a grace time is configured.
 - `--loaddata-from` string. Load users and folders from this file. The file must be specified as absolute path and it must contain a backup obtained using the `dumpdata` REST API or compatible content. The default value is empty or the value of `SFTPGO_LOADDATA_FROM` environment variable.
