Linux mzip Command with Practical Examples

Introduction

In this lab, you will learn how to use the mzip command, a utility for compressing and extracting files and directories in Linux. The mzip command is part of the mtools package, which provides a set of utilities for working with MS-DOS file systems. You will start by understanding the basic usage of the mzip command, and then explore how to compress and extract files and directories using this tool. The lab covers the key steps, including installing the mtools package, creating new archives, and extracting files from existing archives.

The lab is focused on the basic file and directory operations in Linux, providing practical examples of using the mzip command. While the mzip command is still available, it is important to note that it is primarily designed for working with MS-DOS file systems and may not be the most widely used compression tool in modern Linux environments. Users may want to consider more widely adopted compression utilities, such as zip or tar, for their file compression and extraction needs.

Understand the mzip Command

In this step, you will learn about the mzip command, which is a utility for compressing and extracting files and directories in Linux. The mzip command is a part of the mtools package, which provides a set of utilities for working with MS-DOS file systems.

To begin, let's install the mtools package on our Ubuntu 22.04 Docker container:

sudo apt-get update
sudo apt-get install -y mtools

Now, let's explore the basic usage of the mzip command:

mzip --help

Example output:

mzip version 4.0.26
Usage: mzip [-acdfhlLmMnqrtTvVwxz] [-b <bytes>] [-C <dir>] [-o <file>] [-p <password>] [-s <size>] file1 [file2 ...]

The mzip command supports a variety of options for compressing and extracting files and directories. Some of the most commonly used options are:

• -a: Append to an existing archive
• -c: Create a new archive
• -d: Delete files from an archive
• -f: Force overwrite of existing files
• -l: List the contents of an archive
• -x: Extract files from an archive

To create a new archive, you can use the -c option followed by the name of the archive file and the files or directories you want to compress:

mzip -c myarchive.mz file1.txt file2.txt directory1/

This command will create a new archive file named myarchive.mz and add the files file1.txt, file2.txt, and the contents of the directory1/ directory to the archive.

To extract files from an archive, you can use the -x option followed by the name of the archive file:

mzip -x myarchive.mz

This command will extract all the files and directories from the myarchive.mz archive to the current directory.

In the next step, you will learn how to use the mzip command to compress and extract files and directories in more detail.

Compress Files and Directories Using mzip

In this step, you will learn how to use the mzip command to compress files and directories.

First, let's create some sample files and directories to work with:

cd ~/project
mkdir sample_directory
touch sample_file1.txt sample_file2.txt

Now, let's compress the sample_directory and the two text files using the mzip command:

mzip -c sample_archive.mz sample_directory sample_file1.txt sample_file2.txt

This command will create a new archive file named sample_archive.mz and add the sample_directory and the two text files to the archive.

You can verify the contents of the archive using the -l (list) option:

mzip -l sample_archive.mz

Example output:

sample_directory/
sample_file1.txt
sample_file2.txt

To extract the contents of the archive, you can use the -x (extract) option:

mzip -x sample_archive.mz

This will extract all the files and directories from the sample_archive.mz archive to the current directory.

You can also use the mzip command to compress individual files or directories. For example, to compress a single file:

mzip -c sample_file.mz sample_file1.txt

And to compress a directory:

mzip -c sample_directory.mz sample_directory/

Remember, the mzip command is part of the mtools package, which provides a set of utilities for working with MS-DOS file systems. If you need to perform more advanced compression or archiving tasks, you may want to consider using other compression tools like gzip, bzip2, or zip.

Extract Compressed Files and Directories with mzip

In the previous step, you learned how to use the mzip command to compress files and directories. In this step, you will learn how to extract the contents of an mzip archive.

First, let's create a new mzip archive:

cd ~/project
mzip -c sample_archive.mz sample_directory sample_file1.txt sample_file2.txt

Now, let's extract the contents of the sample_archive.mz archive:

mzip -x sample_archive.mz

This command will extract all the files and directories from the sample_archive.mz archive to the current directory.

You can verify the extracted contents by listing the files and directories in the current directory:

ls -l

Example output:

total 8
drwxr-xr-x 2 labex labex 4096 Apr 26 12:34 sample_directory
-rw-r--r-- 1 labex labex    0 Apr 26 12:34 sample_file1.txt
-rw-r--r-- 1 labex labex    0 Apr 26 12:34 sample_file2.txt

As you can see, the sample_directory and the two text files have been extracted from the sample_archive.mz archive.

You can also extract specific files or directories from the archive using the mzip command. For example, to extract only the sample_directory from the archive:

mzip -x sample_archive.mz sample_directory/

This command will extract the sample_directory and its contents from the sample_archive.mz archive.

Remember, the mzip command is part of the mtools package, which provides a set of utilities for working with MS-DOS file systems. If you need to perform more advanced extraction or archiving tasks, you may want to consider using other tools like tar, unzip, or gunzip.

Summary

In this lab, you first learned about the mzip command, which is a utility for compressing and extracting files and directories in Linux. You installed the mtools package, which provides the mzip command, and explored its basic usage and available options. Then, you learned how to use the mzip command to compress files and directories by creating a new archive file, and how to extract files from an existing archive.
