## Amazon CLI


To download a database log file, use the Amazon CLI command [https://docs.amazonaws.cn/cli/latest/reference/rds/download-db-log-file-portion.html](https://docs.amazonaws.cn/cli/latest/reference/rds/download-db-log-file-portion.html). By default, this command downloads only the latest portion of a log file. However, you can download an entire file by specifying the parameter `--starting-token 0`.

The following example shows how to download the entire contents of a log file called *log/ERROR.4* and store it in a local file called *errorlog.txt*.

**Example**  
For Linux, macOS, or Unix:  

```
1. aws rds download-db-log-file-portion \
2.     --db-instance-identifier myexampledb \
3.     --starting-token 0 --output text \
4.     --log-file-name log/ERROR.4 > errorlog.txt
```
For Windows:  

```
1. aws rds download-db-log-file-portion ^
2.     --db-instance-identifier myexampledb ^
3.     --starting-token 0 --output text ^
4.     --log-file-name log/ERROR.4 > errorlog.txt
```

## RDS API


To download a database log file, use the Amazon RDS API [https://docs.amazonaws.cn/AmazonRDS/latest/APIReference/API_DownloadDBLogFilePortion.html](https://docs.amazonaws.cn/AmazonRDS/latest/APIReference/API_DownloadDBLogFilePortion.html) action.
