What is the purpose of the TAR command with the flag -L?

The TAR command is widely used for creating and manipulating tape archives in Unix and Linux systems. The purpose of the TAR command with the -L flag is specifically to set the tape length for multiple tapes in an archive. This feature is particularly useful for managing the storage and retrieval of data across multiple tape drives, ensuring that the data is written and accessed correctly.

When using the -L flag, the user can specify the number of bytes that will be allocated for each tape in the archive. This helps in situations where data exceeds the capacity of a single tape, allowing for a smooth transition from one tape to another without data loss or corruption.

Understanding the role of the -L flag enhances your ability to effectively manage archives, especially in environments where data is frequently backed up or where large volumes of data are handled using tape storage. The other options relate to different functionalities of the TAR command but do not pertain to the specific use of the -L flag.
