In the context of file archiving, what is the role of the -p flag in CPIO?

The -p flag in CPIO is indeed used to preserve the file permissions and ownership of files during the archiving process. When you create an archive or extract files using CPIO, maintaining the original permissions and ownership is critical for ensuring that the files maintain their intended access rights and attributes. This is especially important when transferring files between systems or users, as it ensures the integrity and security of the data being handled.

Preservation of these attributes allows the files to retain their original functionality and access controls after extraction, which can be crucial in multi-user environments or when dealing with sensitive information. Utilizing the -p flag is a common practice to ensure that these important metadata aspects are not lost during the archiving process.
