Overview

COSCMD enables you to use simple command lines to batch-operate objects, such as upload, download, and delete.

Operating Environments

System environment

Windows, Linux, and macOS

Note：

• Local characters should use UTF-8 encoding. Otherwise, exceptions will occur when you operate on Chinese files.
• Ensure that the local time is in sync with UTC. If there is a large deviation between the two, COSCMD might not function properly.

Software requirements

• Python 2.7/3.5/3.6/3.9
• Latest version of pip

  Note：

  You are advised to install the latest version of Python (3.9.0) that is integrated with pip.

Installation and configuration

• For more information about the installation and configuration of the environment, please see Python.
• For more information about the installation and configuration of pip, please see Installation.

Download and Installation

You can install COSCMD in the following three ways:

1.1 Installing with pip

Run the pip command to install COSCMD:

pip install coscmd

After the installation is complete, you can run the -v or --version command to view the version information.

Note：

After installing COSCMD in Windows, you need to add the C:\python_install_dir and C:\python_install_dir\Scripts paths to environment variables.

1.2 Upgrading with pip

After the installation is complete, you can run the following command to upgrade COSCMD:

pip install coscmd -U

2. Installing with the source code (not recommended)

You can click here to download the source code.

git clone https://github.com/tencentyun/coscmd.git
cd coscmd
python setup.py install

Note：

If your Python version is 2.6, installing the dependent libraries with pip may fail. Therefore, this installation method is recommended.

3. Installing from offline

Note：

Ensure that the two devices are installed with the same version of Python. Otherwise, the installation might fail.

# Run the following commands on a device that is connected to the Internet
mkdir coscmd-packages
pip download coscmd -d coscmd-packages
tar -czvf coscmd-packages.tar.gz coscmd-packages

# Copy the installation package to a device that is not connected to the Internet and run the following commands
tar -xzvf coscmd-packages.tar.gz
pip install coscmd --no-index -f coscmd-packages

Generating a configuration file

COSCMD will first read the necessary information from the configuration file before running. By default, COSCMD will read configuration items from ~/.cos.conf.

Note：

Before the configuration, you need to go to the COS console to create a bucket (e.g., configure-bucket-1250000000) for parameter configuration and create a key.

The following is a sample configuration file:

[common]
secret_id = AKIDA6wUmImTMzvXZNbGLCgtusZ2E8mG****
secret_key = TghWBCyf5LIyTcXCoBdw1oRpytWk****
bucket = configure-bucket-1250000000
region = ap-chengdu
max_thread = 5
part_size = 1
retry = 5
timeout = 60
schema = https
verify = md5
anonymous = False

Note：

• schema can be set to http or https (default).
• anonymous can be set to True or False. If set to True, the anonymous mode is used (the signature is empty).
• For more information about the parameter description, please run the coscmd config -h command.

Generating a configuration file via the config command

You can run the config command to automatically generate a configuration file in ~/.cos.conf. The command format is as follows:

coscmd config [OPTION]...<FILE>...
          [-h] --help
          [-a] <SECRET_ID>
          [-s] <SECRET_KEY>
          [-t] <TOKEN>
          [-b] <BucketName-APPID>
             [-r] <REGION> | [-e] <ENDPOINT>
             [-m] <MAX_THREAD>
             [-p] <PART_SIZE>
             [--do-not-use-ssl]
             [--anonymous]   

Note：

Fields enclosed in "[]" are optional, and those in "<>" are required.

The parameters are described as follows:

Option	Parameter Description	Valid Value	Required
-a	Key ID, which can be obtained at Manage API Key	String	Yes
-s	Key, which can be obtained at Manage API Key	String	Yes
-t	Temporary key token, which needs to be specified in the x-cos-security-token header when a temporary key is used.	String	No
-b	Name of the specified bucket, formatted as BucketName-APPID. For more information, please see Naming Conventions. If this is your first time using COSCMD, you need to create a bucket in the COS console to configure COSCMD.	String	Yes
-r	Region of the bucket. For more information, please see Regions and Access Endpoints.	String	Yes
-e	ENDPOINT of the request. Once configured, the REGION parameter will be invalidated. If you use the default endpoint, this parameter is formatted as cos.<region>.myqcloud.com; if you use a global acceleration endpoint, the format is cos.accelerate.myqcloud.com.	String	No
-m	Maximum number of threads in a multi-thread operation (default: 5; value range: 1-30)	Number	No
-p	Size of the multipart upload part, in MB (default: 1; value range: 1-1000)	Number	No
--do-not-use-ssl	Uses the HTTP protocol instead of HTTPS	String	No
--anonymous	Anonymous operation (without carrying a signature)	String	No

The following sample shows how to use the config command:

coscmd config -a AChT4ThiXAbpBDEFGhT4ThiXAbp**** -s WE54wreefvds3462refgwewe**** -b configure-bucket-1250000000 -r ap-chengdu

Common Commands

Specifying a bucket and its region

If you do not specify the bucket and region in the commands, the commands take effect for the bucket that is used to configure COSCMD. To perform operations on another bucket, you need to specify the bucket and the region where the bucket resides.

Note：

• Use the -b <bucketname-appid> parameter to specify the bucket name, which must be formatted as BucketName-APPID.
• Use the -r <region> parameter to specify the region where the bucket resides.

• Command syntax

  coscmd -b <BucketName-APPID> -r <region> <action> ...
  

• Sample: creating a bucket named examplebucket that resides in the Beijing region

  coscmd -b examplebucket-1250000000 -r ap-beijing createbucket
  

• Sample: uploading “picture.jpg” from D drive to the examplebucket bucket

  coscmd -b examplebucket-1250000000 -r ap-beijing upload D:/picture.jpg /
  

Command for specifying the configuration file and log file paths

If you do not specify the configuration file path, ~/.cos.conf will be used by default. Similarly, if you do not specify the log file path, ~/.cos.log will be used by default.

Note：

• Use the -c <conf_path> parameter to specify the configuration file path. COSCMD will read configuration information from the path when running.
• Use the -l <log_conf> parameter to specify the log file path. COSCMD will output the logs generated at runtime to the log files in the path.

• Command syntax

  coscmd -c <conf_path> -l <log_conf> <action> ...
  

• Sample: setting the configuration file’s path to /data/home/cos_conf and the log path to /data/home/cos_log, and creating a bucket named examplebucket in the Beijing region

  coscmd -c /data/home/cos_conf -l /data/home/cos_log -b examplebucket-1250000000 -r ap-beijing createbucket
  

Running commands in debugging mode

If -d or -debug is added before a command, detailed operation information will be displayed when executing the command, as shown in the example below:

• Command syntax

  coscmd -d upload <localpath> <cospath>
  

• Sample: outputting detailed information upon the upload

  coscmd -d upload -rs D:/folder/ /
  

Running commands in silence mode

You can prefix -s or --silence in each command so that no message will be output. A command sample is as follows:

• Command syntax

  coscmd -s upload <localpath> <cospath>
  

• Sample:

  coscmd -s upload D:/picture.jpg /
  

Common Bucket Commands

Creating a bucket

Note：

Please specify -b <bucketname-appid> and -r <region> when you run the coscmd createbucket command; otherwise, an error may be reported. This is because if the bucket and region are not specified, this command takes effect for the bucket that is used to configure COSCMD.

• Command syntax

  coscmd -b <BucketName-APPID> createbucket
  

• Sample: creating a bucket named examplebucket that resides in the Beijing region

  coscmd -b examplebucket-1250000000 -r ap-beijing createbucket
  

Deleting a bucket

Note：

coscmd deletebucket takes effect only for the bucket that is used to configure COSCMD. To delete another bucket, run the command with the -b <bucketname-appid> and -r <region> parameters specified.

• Command syntax

  coscmd -b <BucketName-APPID> deletebucket
  

• Sample: deleting empty buckets

  coscmd -b examplebucket-1250000000 -r ap-beijing deletebucket
  

• Sample: forcibly deleting a non-empty bucket

  coscmd -b examplebucket-1250000000 -r ap-beijing deletebucket -f
  

Note：

The -f parameter will forcibly delete the bucket, including all files, noncurrent folders (if versioning is enabled), and incomplete multipart uploads.

Common Object Commands

Uploading a file

• Command syntax for uploading a file

  coscmd upload <localpath> <cospath>
  

Note：

Replace "localpath" and "cospath" enclosed in "<>" with the path of the local file to upload and the COS storage path, respectively.

• Sample: uploading “picture.jpg” in D drive to the "doc" folder of COS

  coscmd upload D:/picture.jpg doc/
  

• Sample: uploading “picture.jpg” in the "doc" folder in D drive to the "doc" folder of COS

  coscmd upload D:/doc/picture.jpg doc/
  

• Sample: uploading a file to the ARCHIVE storage class to the "doc" directory of COS

  coscmd upload D:/picture.jpg doc/ -H "{'x-cos-storage-class':'Archive'}"
  

Note：

When you set the HTTP header with the -H parameter, please use the JSON format, for example, coscmd upload -H "{'x-cos-storage-class':'Archive','Content-Language':'zh-CN'}" <localpath> <cospath>. For more information about the headers, please see PUT Object.

• Sample: setting meta attributes and uploading a file to the “doc” folder of COS

  coscmd upload D:/picture.jpg doc/ -H "{'x-cos-meta-example':'example'}"
  

Uploading a folder

• Command syntax for uploading a folder

  coscmd upload -r <localpath> <cospath>
  

Note：

Windows users are recommended to use the upload command in cmd or PowerShell that comes with the system. Other tools, such as Git Bash, have a different command path resolution strategy than PowerShell and can cause users' files to be uploaded to a wrong path.

• Sample: uploading the "doc" folder in D drive to the root directory of COS

  coscmd upload -r D:/doc /
  

• Sample: uploading the "doc" folder in D drive to the "doc" folder of COS

  coscmd upload -r D:/doc doc
  

• Sample: uploading files synchronously (files with the same name, MD5 checksum, and file size will be skipped)

  coscmd upload -rs D:/doc doc
  

Note：

Use the -s parameter to upload files synchronously while skipping those with the same MD5 value (please note that the source files in COS must have been uploaded using COSCMD v1.8.3.2 or above; the x-cos-meta-md5 header is included by default).

• Sample: uploading files synchronously (files with the same name and file size will be skipped)

  coscmd upload -rs --skipmd5 D:/doc doc
  

Note：

The -s parameter allows synchronous upload, and the --skipmd5 parameters can be used to skip files with the same name and same file size.

• Sample: uploading the folder synchronously and deleting files that are deleted in the "doc" folder in D drive

  coscmd upload -rs --delete D:/doc /
  

• Sample: ignoring .txt and .doc files in the "doc" folder in D drive

  coscmd upload -rs D:/doc / --ignore *.txt,*.doc
  

Note：

When uploading folders, you can ignore certain types of files by using the --ignore parameter, or filter certain types of files by using --include. Multiple shell wildcard rules (separated by commas ,) are supported. To ignore a specified extension, , must be added at the end, or "" must be used to enclose the extension.

• Sample: uploading .txt and .doc files in the "doc" folder in D drive

  coscmd upload -rs D:/doc / --include *.txt,*.doc
  

Note：

• If the file to upload is larger than 10 MB, COSCMD will upload with multipart upload. The command is coscmd upload <localpath> <cospath> (same as simple upload).
• COSCMD supports checkpoint restart to resume the upload of large files. When the multipart upload of a large file fails, only the failed parts will be uploaded when the operation is resumed instead of starting over from scratch (please ensure that the directory and content of the re-uploaded file are consistent with the uploaded directory).
• COSCMD performs MD5 verification on each part during multipart upload.
• When COSCMD uploads a file, the x-cos-meta-md5 header is carried by default, whose value is the file's MD5 checksum. If the command has carried the --skipmd5 parameter, this header will not be carried.

Querying a file list

The query command is as follows:

• Command syntax

  coscmd list <cospath>
  

• Sample: recursively querying the list of all files prefixed with "doc/" in this bucket

  coscmd list doc/
  

• Sample: recursively querying the file list, number of files, and the file sizes of a bucket

  coscmd list -ar
  

• Sample: recursively querying the list of all files prefixed with "examplefolder"

  coscmd list examplefolder/ -ar
  

• Sample: querying the historical versions of all files in a bucket

  coscmd list -v
  

Note：

• Replace "cospath" enclosed in "<>" with the COS path of the file list to query. If <cospath> is empty, the root directory of the current bucket is queried.
• Use -a to query all files.
• Use -r to query files recursively. The number and total size of the files are listed at the end of the returned result.
• Use -n num to set the maximum number of files to query.

Viewing the file information

The command is as follows:

• Command syntax

  coscmd info <cospath> 
  

• Sample: viewing the metadata of "doc/picture.jpg"

  coscmd info doc/picture.jpg
  

Note：

Replace "cospath" enclosed in "<>" with the COS path of the file to query.

Downloading a file or folder

Command syntax for downloading a file

coscmd download <cospath> <localpath>

Note：

Replace "cospath" and "localpath" enclosed in "<>" with the COS path of the file to download and the local storage path, respectively.

• Sample: downloading the "doc/picture.jpg" file in COS to "D:/picture.jpg"

  coscmd download doc/picture.jpg D:/picture.jpg
  

• Sample: downloading the "doc/picture.jpg" file in COS to "D:/picture.jpg"

  coscmd download doc/picture.jpg D:/
  

• Sample: downloading a specified version of "picture.jpg" to D drive

  coscmd download picture.jpg --versionId MTg0NDUxMzc2OTM4NTExNTg7Tjg D:/
  

Command syntax for downloading a folder

coscmd download -r <cospath> <localpath>

• Sample: downloading the "doc" folder to "D:/folder/doc"

  coscmd download -r doc D:/folder/
  

• Sample: downloading files in the root directory while ignoring those in the doc directory that is under the root directory

  coscmd download -r / D:/ --ignore doc/*
  

• Sample: downloading all files in the root directory of the current bucket and overwriting local files

  coscmd download -rf / D:/examplefolder/
  

Note：

If a file with the same name exists locally, the download will fail. In this case, you need to use the -f parameter to overwrite the local file.

• Sample: synchronously downloading all files in the root directory of the current bucket while skipping those with the same filename and MD5 checksum

  coscmd download -rs / D:/examplefolder
  

Note：

Use the -s or --sync parameter to skip identical files that already exist locally when downloading a folder (provided that the downloaded files were uploaded via the COSCMD upload API and the x- cos-meta-md5 header was included).

• Sample: synchronously downloading all files in the root directory of the current bucket while skipping those with the same filename and file size

  coscmd download -rs --skipmd5 / D:/examplefolder
  

• Sample: synchronously downloading all files in the root directory of the current bucket and deleting local files that have been deleted in cloud

  coscmd download -rs --delete / D:/examplefolder
  

• Sample: ignoring .txt or .doc files

  coscmd download -rs / D:/examplefolder --ignore *.txt,*.doc
  

Note：

When downloading folders, you can ignore certain types of files by using the --ignore parameter, or filter certain types of files by using --include. Multiple shell wildcard rules (separated by commas ,) are supported. To ignore a specified extension, , must be added at the end, or "" must be used to enclose the extension.

• Sample: filtering .txt and .doc files

  coscmd download -rs / D:/examplefolder --include *.txt,*.doc
  

Note：

Since the old mget API is no longer in use, please use the download API for multipart downloads.

Getting signed download URLs

• Command syntax

  coscmd signurl <cospath>
  

• Sample: generating a signed URL for "doc/picture.jpg"

  coscmd signurl doc/picture.jpg
  

• Sample: generating a signed URL that is effective for 100 seconds for "doc/picture.jpg"

  coscmd signurl doc/picture.jpg -t 100
  

Note：

• Replace "cospath" enclosed in "<>" with the COS path of the file for which you need to get the download URL.
• The -t time parameter sets the effective time (in seconds) of the URL signature. The default value is 10000.

Deleting a file or folder

Command syntax for deleting a file

coscmd delete <cospath>

Note：

Replace "cospath" enclosed in "<>" with the COS path of the file to delete. You will be prompted to confirm this operation.

• Sample: deleting the "doc/exampleobject.txt" file

  coscmd delete doc/exampleobject.txt
  

• Sample: deleting files with version IDs

  coscmd delete doc/exampleobject.txt --versionId MTg0NDUxMzc4ODA3NTgyMTErEWN

• Sample: deleting the folder/doc folder

  coscmd delete -r folder/doc
  

• Sample: deleting all files with version IDs in the doc directory

  coscmd delete -r doc/ --versions
  

Note：

• You need to enter y to confirm a batch delete operation. You can skip this step if the -f parameter is used.
• Note that the delete folder command will delete the current folder as well as the files in it. To delete a versioning-enabled file, you need to specify a version ID.

Viewing incomplete multipart uploads

• Command syntax

  coscmd listparts <cospath>
  

• Sample: listing incomplete multipart uploads prefixed with "doc/"

  coscmd listparts doc/
  

Aborting incomplete multipart uploads
