Use the [`influx query` command](/influxdb/version/reference/cli/influx/query) to query data in InfluxDB using Flux.
|
|
Pass Flux queries to the command as either a file or via stdin.
|
|
|
|
###### Run a query from a file
|
|
|
|
```bash
|
|
influx query --file /path/to/query.flux
|
|
```
|
|
|
|
###### Pass raw Flux via stdin pipe
|
|
|
|
```bash
|
|
influx query - # Return to open the pipe
|
|
|
|
data = from(bucket: "example-bucket") |> range(start: -10m) # ...
|
|
# Linux & macOS: <ctrl-d> to close the pipe and submit the command
|
|
# Windows: <enter>, then <ctrl-d>, then <enter> to close the pipe and submit the command
|
|
```

#### Remove unnecessary columns in large datasets
|
|
When using the `influx query` command to query and download large datasets,
|
|
drop columns such as `_start` and `_stop` to optimize the download file size.
|
|
|
|
```js
|
|
// ...
|
|
|> drop(columns: ["_start", "_stop"])
|
|
```
