What command is used to extract files from a compressed archive?

The command used to extract files from a compressed archive is represented correctly. The command structure includes several components: "tar" is the command itself for manipulating archive files. The option "-x" specifically signifies the extraction of files from an archive. The "v" stands for verbose, which provides information on the files being extracted during the operation. Finally, the "f" option indicates that a file name is specified and follows right after the command.

This command is typically used for uncompressed tar files (often with a .tar extension). For compressed archives, additional flags might be involved to handle different compression formats, such as gzip or bzip2. Options with "z" or "j" would account for those scenarios. Therefore, while the choice provided accurately addresses the extraction of files from a plain tar archive, it does not account for those that are compressed.
