# Write data with the influx CLI

This page documents an earlier version of InfluxDB OSS. [InfluxDB 3 Core](/influxdb3/core/) is the latest stable version.

#### API token hashing is enabled by default in InfluxDB OSS 2.9.0

Stronger token security: tokens are stored as hashes on disk, so a copy of the database file doesn’t expose usable tokens. Existing tokens are hashed on first startup and the original strings can’t be recovered afterward — **capture any plaintext tokens you still need before you upgrade**.

For more information, see [Token hashing](/influxdb/v2/admin/tokens/#token-hashing).

To write data from the command line, use the [`influx write` command](/influxdb/v2/reference/cli/influx/write/). Include the following in your command:

| Requirement | Include by |
| --- | --- |
| Organization | Use the -o,--org, or --org-id flags. |
| Bucket | Use the -b, --bucket, or --bucket-id flags. |
| Precision | Use the -p, --precision flag. |
| API token | Set the INFLUX_TOKEN environment variable or use the t, --token flag. |
| Data | Write data using line protocol or annotated CSV. Pass a file with the -f, --file flag. |

*See [Line protocol](/influxdb/v2/reference/syntax/line-protocol/) and [Annotated CSV](/influxdb/v2/reference/syntax/annotated-csv)*

#### Example influx write commands

##### Write a single line of line protocol

```sh
influx write \
  -b bucketName \
  -o orgName \
  -p s \
  'myMeasurement,host=myHost testField="testData" 1556896326'
```

##### Write line protocol from a file

```sh
influx write \
  -b bucketName \
  -o orgName \
  -p s \
  --format=lp
  -f /path/to/line-protocol.txt
```

##### Write annotated CSV from a file

```sh
influx write \
  -b bucketName \
  -o orgName \
  -p s \
  --format=csv
  -f /path/to/data.csv
```
