Creating a gzip-compressed tar archive | LinuC Level 1 101 Exam original practice question

1.02.2Basic

Create project.tar.gz from the project directory using gzip compression.

Keep the original directory.

Which GNU tar command is appropriate?

Hint 1: Focus on the requirement

Separate tar's archive operation from the compression format and archive filename operand.

Hint 2: Key terms

Review the short command and filesystem definitions before comparing the choices.

tar: Combines files and directories into an archive stream.
Create operation: The tar operation that builds a new archive.
gzip: The compression format selected by tar's z flag.
File operand: The tar flag that makes the following argument the archive filename.

Detailed explanation

Correcttar -czf project.tar.gz project

Correct. tar -czf project.tar.gz project creates the gzip-compressed archive.

Incorrecttar -xzf project.tar.gz project

Incorrect. -x extracts an archive rather than creating one.

Incorrecttar -cjf project.tar.gz project

Incorrect. -j selects bzip2, not gzip.

Incorrecttar -cJf project.tar.gz project

Incorrect. -J selects xz, not gzip.

Try it yourself

An example you can run in a temporary verification environment.

tmp=$(mktemp -d); mkdir "$tmp/project"; printf data >"$tmp/project/item"; (cd "$tmp" && tar -czf project.tar.gz project && tar -tzf project.tar.gz); rm -rf "$tmp"

Expected result

project/とproject/itemを含む一覧

Key points

c creates
z means gzip
f is followed by archive name

Notes

Environment: GNU tar 1.x / gzip / 一時ディレクトリ
Use disposable files and directories for destructive or timestamp-related checks.
Command details can vary slightly between GNU and non-GNU implementations.

Foundation review

Place the operation

Creating a gzip-compressed archive requires the create operation, gzip selection, and an output archive name.

Check the side effect

List the archive after creation to confirm that the expected members were stored.
