Question 18

Explanation

Answer:

# tar -cjf /home/bin.tar.bz2 /usr/bin

Explanation

1. Command Breakdown:

   • tar: This command is used for creating and manipulating tar archives.

   • -c: Creates a new archive.

   • -j: Compresses the archive using bzip2 compression, which is more efficient than gzip.

   • -f: Specifies the file name for the archive (/home/bin.tar.bz2).

   • /usr/bin: Specifies the directory to be archived.

2. Alternative Method: If you prefer creating an uncompressed .tar file first and then compressing it with bzip2, use:

   # tar -cf /home/bin.tar /usr/bin && bzip2 /home/bin.tar

   • This creates an uncompressed bin.tar file and then compresses it to bin.tar.bz2.

Key Takeaway

Using -cjf directly is generally faster and simpler, making it ideal for the exam.
