You can use the -h option to view all options supported by ossutil.
To view the options that a command supports, run the ossutil help [command] command such as ossutil help cp.
The following section describes common options that can be added to most commands supported by ossutil:
- -c, --config-file
Specifies the configuration file path of ossutil. ossutil reads the configuration file during the startup, and writes configurations to the file by using the config command. When you manage buckets that belong to different accounts, you can generate multiple configuration files, and set one of these configuration files to the default configuration file. When you manage a bucket that belongs to other accounts, you can use the -c option to specify the corresponding configuration file.
- -e, --endpoint
Specifies the endpoint of a bucket. When you manage buckets across regions, you can use the -e option to specify the regions.
- -i, --access-key-id
Specifies the AccessKey ID used to access OSS. When you manage buckets that belong to different accounts, you can use the -i option to specify the corresponding AccessKey IDs.
- -k, --access-key-secret
Specifies the AccessKey secret used to access OSS. When you manage buckets that belong to different accounts, you can use the -k option to specify the corresponding AccessKey secrets.
Generates the ossutil.log file in the current working folder. The default value is null, which indicates that no log files are generated. Valid values: info and debug.
- Default: The value of --loglevel is null, which indicates that no log files are generated.
- info: generates operations logs of ossutil.
./ossutil [command] --loglevel=info
- debug: generates logs that contain HTTP requests and responses and original signature
strings to locate problems.
./ossutil [command] --loglevel=debug
- --proxy-host, --proxy-user, and --proxy-pwd
If your environment requires a proxy server to access websites, you must use these three options to specify the information of the proxy server. ossutil uses the specified information to access OSS through the corresponding proxy server.Example:
./ossutil ls oss://bucket1 --proxy-host http://47.88. **.**:3128 --proxy-user test --proxy-pwd test
