Use the influx query command 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

influx query --file /path/to/query.flux

Pass raw Flux via stdin pipe

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.

// ...
    |> drop(columns: ["_start", "_stop"])
