		Description: `
Providing no argument to the config command will print the active configuration.
When an argument is provided, the active config will be switched to the config with
a name matching that of the argument provided.

Examples:
	# show active config
	influx config

	# set active config to previously active config
	influx config -

	# set active config
	influx config $CONFIG_NAME

The influx config command displays the active InfluxDB connection configuration and
manages multiple connection configurations stored, by default, in ~/.influxdbv2/configs.
Each connection includes a URL, token, associated organization, and active setting.
InfluxDB reads the token from the active connection configuration, so you don't have
to manually enter a token to log into InfluxDB.

For information about the config command, see
https://docs.influxdata.com/influxdb/latest/reference/cli/influx/config/
