Google cloud platform - How to copy only files from many subdirectory under the directory to another project bucket in GCP?

To copy only files from many subdirectories under a directory to another project's bucket in Google Cloud Platform (GCP), you can use the gsutil command-line tool. Here's how you can do it:

  1. Install and Authenticate gsutil: If you haven't already, install the Google Cloud SDK, which includes gsutil. Then, authenticate gsutil with your Google Cloud account using the gcloud auth login command.

  2. Use gsutil cp Command: You can use the gsutil cp command to copy files from one location to another. To copy only files (not directories) from many subdirectories under a directory, you can use the wildcard (*) character in the source path.

    For example, suppose you have a directory source_directory with multiple subdirectories and files, and you want to copy only the files to a bucket named destination_bucket in another project. You can use the following command:

    gsutil -m cp -r source_directory/*/*.txt gs://destination_bucket/

    This command copies all .txt files from all subdirectories under source_directory to the root of destination_bucket in another project.

    Explanation of the command:

    • -m: Enables multithreaded/multipart copying for faster performance.
    • cp: Specifies the copy command.
    • -r: Indicates recursive copying.
    • source_directory/*/*.txt: Specifies the source files matching the pattern of any .txt files (*.txt) within any subdirectory (*) of source_directory.
    • gs://destination_bucket/: Specifies the destination bucket.

    Adjust the source and destination paths and patterns (*.txt, etc.) as needed based on your specific requirements.

  3. Ensure Permissions: Make sure that the service account used to authenticate gsutil has the necessary permissions to read from the source bucket and write to the destination bucket in both projects.

By following these steps and using the gsutil cp command with appropriate patterns, you can copy only files from many subdirectories under a directory to another project's bucket in GCP.

Examples

  1. GCP copy files from subdirectories to another bucket

    • Description: Users might search for methods to copy files from multiple subdirectories under a directory to another bucket in Google Cloud Platform (GCP).
    gsutil -m cp -r gs://source-bucket-name/path/to/directory/** gs://destination-bucket-name/

  2. GCP copy files from specific subdirectories to another bucket

    • Description: This query is about copying files only from specific subdirectories under a directory to another bucket in GCP.
    gsutil -m cp -r gs://source-bucket-name/path/to/directory/{subdir1,subdir2}/* gs://destination-bucket-name/

  3. GCP copy files recursively from subdirectories to another bucket

    • Description: Users might want to copy files recursively, including those from subdirectories, to another bucket in GCP.
    gsutil -m cp -r gs://source-bucket-name/path/to/directory/ gs://destination-bucket-name/

  4. GCP copy files by subdirectory to another bucket

    • Description: This query seeks methods to copy files grouped by subdirectory to another bucket in GCP.
    gsutil -m cp -r gs://source-bucket-name/path/to/directory/subdirectory* gs://destination-bucket-name/

  5. GCP move files from subdirectories to another bucket

    • Description: Users might search for ways to move files from subdirectories to another bucket in GCP, which involves copying and deleting files.
    gsutil -m mv -r gs://source-bucket-name/path/to/directory/** gs://destination-bucket-name/

  6. GCP sync files from subdirectories to another bucket

    • Description: This query is about synchronizing files, including those from subdirectories, to another bucket in GCP, ensuring that the destination is an exact copy of the source.
    gsutil -m rsync -r gs://source-bucket-name/path/to/directory/ gs://destination-bucket-name/

  7. GCP transfer files from subdirectories to another bucket

    • Description: Users might want to transfer files, including those from subdirectories, to another bucket in GCP.
    gsutil -m cp -r gs://source-bucket-name/path/to/directory/** gs://destination-bucket-name/

  8. GCP copy files from multiple subdirectories to another bucket

    • Description: This query is about copying files from multiple subdirectories under a directory to another bucket in GCP.
    gsutil -m cp -r gs://source-bucket-name/path/to/directory/** gs://destination-bucket-name/

  9. GCP copy files with specific extensions from subdirectories

    • Description: Users might search for methods to copy files with specific extensions from subdirectories to another bucket in GCP.
    gsutil -m cp gs://source-bucket-name/path/to/directory/**/*.jpg gs://destination-bucket-name/

  10. GCP copy files from subdirectories preserving directory structure

    • Description: This query is about copying files from subdirectories while preserving the directory structure to another bucket in GCP.
    gsutil -m cp -r gs://source-bucket-name/path/to/directory/** gs://destination-bucket-name/path/to/directory/
