Ubuntu Compress File and Change Ownership Command

This article explains how to compress a file and assign new ownership permissions in Ubuntu Linux. While there is no single native flag to perform both actions atomically, you can achieve this result efficiently by chaining standard compression tools with the change ownership command. The following guide provides the exact syntax required to compress a document and immediately assign it to a specific user and group.

In Ubuntu, compression utilities like gzip and tar create new files that default to the current user’s ownership. To change the ownership of the resulting compressed file, you must execute a change ownership command immediately after compression. You can combine these steps into one line using the logical AND operator.

To compress a file using gzip and change its ownership simultaneously, run the following command in your terminal:

gzip filename && sudo chown user:group filename.gz

Replace filename with your actual file name, user with the target username, and group with the target group name. The && operator ensures the ownership change only occurs if the compression succeeds. The resulting file will be named filename.gz.

If you are creating a tar archive, the process is similar. Use this command to create a compressed archive and set its filesystem ownership:

tar -czf archive.tar.gz /path/to/file && sudo chown user:group archive.tar.gz

Note that you may need sudo privileges to change ownership to a user other than yourself. Ensure you have the necessary permissions before executing the chown portion of the command. This method ensures your compressed data is secured under the correct user account immediately upon creation.
