010-160 Archiving and Compression 2

Question 1

Which tar option extracts files to a specific directory instead of the current one?

Accepted Answer

-C /path/to/dir

Answer

The -C option changes the working directory before performing any operations, so files are extracted there.

Question 2

What does the `gzip -k` flag do?

Accepted Answer

Keep the original file after compression

Answer

The -k (keep) flag tells gzip to retain the original file instead of replacing it with the compressed version.

Question 3

Which command lists the contents of a .tar.bz2 file without extracting it?

Accepted Answer

tar -tjf archive.tar.bz2

Answer

The -t flag lists contents, -j specifies bzip2, and -f specifies the filename — no extraction occurs.

Question 4

What compression format does the `xz` command produce by default?

Accepted Answer

.xz using LZMA2

Answer

The xz utility uses the LZMA2 algorithm and produces files with the .xz extension by default.

Question 5

Which tar option appends files to an existing uncompressed tar archive?

Accepted Answer

-r

Answer

The -r (append) option adds files to the end of an existing archive without recreating it.
