Whether you're a command-line aficionado seeking the precision of text-based interactions or a GUI enthusiast preferring a visual approach, this article has you covered.

By the end, you'll be equipped with the knowledge to streamline your file management tasks, reduce storage space, and effortlessly share your data.

How to Zip a Folder in Ubuntu Linux / Debian Linux Using the CLI Method

Step 1: Install the zip and unzip Commands

Before using the zip command, ensure that it is installed on your system. Open the terminal and type the following command to install both zip and unzip:

$ sudo apt install zip unzip

Step 2: Zip a Folder / Compress a Folder Using Zip Command

To compress a folder using the zip command, use the following syntax:

$ zip -r give_zipped_file_a_name.zip folder_you_want_to_zip

For example:

$ zip -r archive.zip directory/

You can also zip multiple folders. To do that, Run:

$ zip -r filename.zip folder1 folder2

Or specify the full paths:

$ zip -r filename.zip /path/to/folder1 /path/to/file2

For example, to create a compressed archive named data.zip of the data folder in the current directory, run:

$ zip -r data.zip data/

Once the directory is zipped, verify the creation of the zip file by simply typing the ls command:

ls

Alternatively, you can use the following command that confirms the zip file creation with date and time details:

$ ls -l data.zip

Step 3: Password Protect the Zip File (Optional)

To encrypt the zip file with a password, use the -e option:

$ zip -r -e data.zip data/

You will be prompted to enter and verify the password.

Step 4: Explore Additional Options

The zip command provides various options for customization. Here are some examples:

Option	Description
-f	Only include changed files in the archive.
-u	Include changed or new files in the archive.
-d	Remove specified entries from the archive.
-m	Add files to the archive and delete the original files (move into zipfile).
-r	Add files to the archive and delete the original files (move into zip file).
-j	Do not record directory names during compression.
-0	Do not compress files, store them in the archive as-is.
-l	Convert LF to CR LF: Convert newline characters during compression.
-1	Use faster compression settings.
-9	Use maximum compression settings.
-q	Suppress normal output, print only errors.
-v	Print detailed information about the compression process.

-y	Store symbolic links as the link instead of the referenced file.
-e	Password-protect the archive entries.
-n	Exclude files with specified suffixes from compression.
-h2	Display additional help information.

These descriptions provide a clear overview of each zip command option and its purpose.

Let’s implement some of the options mentioned above:

$ zip -r -u filename.zip folder  # Update existing zip file
$ zip -r -9 filename.zip folder  # Use maximum compression
$ zip -r -x '*.log' filename.zip folder  # Exclude files with a specific extension

Let’s explore more options using the man command:

$ man zip

The man command in Linux is used to display the manual pages for a given command. Manual pages are documentation that provides information about the usage, options, and details of a command or program.

The man zip command above will display detailed information about the zip command, including its syntax, options, and usage examples. You can navigate through the manual page using the arrow keys (nudge keys) and to exit the manual page, press the q key.

The man command is a valuable resource for learning more about various commands and understanding how to use them effectively in a Unix-like operating system, including Linux.
