Answer 2

Answer:

B. tar ztf archive.tgz




Explanation:

1. Purpose of the Command:
   The command tar ztf archive.tgz lists the contents of a gzip-compressed tar archive (*.tgz or *.tar.gz) without extracting it. The flags used are:

• z: Decompress using gzip.

• t: List contents.

• f: Specify the archive file.

• 
  

2. Why Other Options Are Incorrect:

• Creates a new archive (c flag) but does not display contents.

• Similar to A, but uses t to list. However, it’s redundant; tar ztf is the direct method.

• 
  

• This decompresses the file first (losing original compression) and pipes it to tar, but it extracts (xvf) instead of listing contents.

• A. gzip archive.tgz | tar xvf -

• C. gzip -d archive.tgz | tar tvf -

• D. tar cf archive.tgz

3. Key Advantage of tar ztf:
   It’s a single-step solution to inspect compressed archives, avoiding unnecessary decompression or extraction.
