Practical Zip Command Examples

The zip command in Linux offers unmatched convenience for handling files on Linux, letting you compress, secure, and transfer data effortlessly.

Whether you are a Linux novice or a system admin, a powerful Linux VPS can maximize the efficiency and speed of your workflows.

Let’s go through the examples of this Linux zip tutorial to learn about the Best ways to compress and organize files in Linux using zip and run them on your Linux system to start compressing, securing, and managing your files like a pro.

1. Create a ZIP Archive

To create a zip archive in Linux, use the zip command in Linux followed by the archive name and the files or directories you wish to compress.

This is the most basic and common use case for the zip command.

• Main Syntax:

zip <archive-name>.zip <file1> <file2> ...

• Example:

To create a zip archive named documents.zip containing the opera_project.txt file, run:

zip documents.zip opera_project.txt

Output

 adding: opera_project.txt (deflated 18%)

Using the zip command to create compressed archives helps with managing files efficiently on Linux.

This command is especially useful when compressing data for backups or reducing file size for easier sharing.

2. List ZIP File Contents

To list the contents of a ZIP archive without extracting it, you can use the -sf option with the zip command.

This will show you the files contained within the archive.

• Main Syntax:

zip -sf <archive-name>.zip

• Example:

To list the contents of the files.zip archive, run:

zip -sf files.zip

Output

Archive:  files.zip
  Length    Date    Time    Name
---------  ---------- -----   ----
     1234  12-12-2024 10:00 opera_project.txt
---------                     -------
     1234                     1 file

Using the -sf option helps you quickly inspect the contents of a ZIP file without extracting anything, which is handy for reviewing archives before decompressing them.

3. Add Specific File Types to a ZIP Archive

To add specific file types to a ZIP archive, use the -i option.

This option allows you to specify certain file extensions or patterns that you want to include, making the compression process more selective.

• Main Syntax:

zip -i "*.txt" <archive-name>.zip <file1> <file2> ...

• Example:

To add only .txt files from the directory to the documents.zip archive, run:

zip -i "*.txt" documents.zip opera_project.txt report.txt

Output

  adding: opera_project.txt (deflated 18%)
  adding: report.txt (deflated 20%)

Using the -i option with zip lets you include specific file types in your archive, providing more control over the contents.

This is particularly useful when you want to compress only certain file extensions without including others.

4. Adjust ZIP Compression

You can control the compression level in a ZIP archive using the -# option, where # is a number between 0 and 9, indicating the level of compression.

A higher number results in better compression but slower performance.

• Main Syntax:

zip -9 <archive-name>.zip <file1> <file2> ...

• Example:

To create a ZIP archive with maximum compression level (9) for the opera_project.txt file, run:

zip -9 documents.zip opera_project.txt

Output

  adding: opera_project.txt (deflated 58%)

5. Compress Both Files and Directories into a ZIP Archive

The -r option allows you to recursively include all files and subdirectories within a specified directory.

You can use the zip command in Linux to compress both files and directories into a single archive.

• Main syntax:

zip -r <archive-name>.zip <directory-name> <file1> <file2> ...

• Example:

To compress the opera_project directory and the report.txt file into the documents.zip archive, run:

zip -r documents.zip opera_project report.txt

Output

  adding: opera_project/ (stored 0%)
  adding: opera_project/file1.txt (deflated 20%)
  adding: report.txt (deflated 30%)

Using the -r option ensures that all files and subdirectories within the specified directory are included, which is useful for creating complete backups or archiving entire projects.

5-1. Also, you can combine the -r option for directories and the -q option for quiet operation to compress both files and directories while minimizing output during the process:

• Main syntax:

zip -r -q <archive-name>.zip <directory-name> <file1> <file2> ...

• Example:

To compress the opera_project directory and the report.txt file into the documents.zip archive with no output, run:

zip -r -q documents.zip opera_project report.txt

Output

No output, since -q suppresses messages.

Using the zip command in Linux to compress files and directories with the -q option is perfect for users who prefer a quieter, less cluttered terminal when creating archives.

6. Remove Files from an Existing Zip Archive

The -d option in the zip command in Linux allows you to delete specific files from an existing .zip archive.

This is particularly useful for managing compressed files on Linux without needing to recreate the entire archive, which saves both time and disk space.

• Main Syntax:

zip -d <archive-name>.zip <file-to-delete>

• Example:

To delete a file named opera_notes.txt from the project.zip archive, run:

zip -d project.zip opera_notes.txt

Output

deleting: opera_notes.txt

By using the Linux zip command with the -d option, you can efficiently manage and organize your data within .zip files.

7. Update Existing Files in a Zip Archive

The -u option in the zip command in Linux lets you update files within an existing .zip archive, ensuring only modified files are re-added to save time and disk space.

This option is especially useful when you need to maintain Linux zip multiple files in a current state without recreating the entire archive.

• Main Syntax:

zip -u <archive-name>.zip <file-to-update>

• Example:

To update opera_project.txt in the documents.zip archive, run:

zip -u documents.zip opera_project.txt

Output

updating: opera_project.txt (deflated 20%)

8. Move Files into a Zip Archive

The -m option in the zip command compresses files and then removes the original files, effectively moving files into a zip archive.

This is useful when you want to compress and clean up the source files in one action.

• Main Syntax:

zip -m <archive-name>.zip <file-to-move>

• Example:

To move opera_project.txt into documents.zip and remove it from the original location, run:

zip -m documents.zip opera_project.txt

Output

adding: opera_project.txt (deflated 18%)

This method is an efficient way to manage zip files efficiently on Linux.

It’s ideal for those looking for a quick solution for How to create, update, and manage zip archives in Linux, as it allows for easy file organization and space optimization.

9. Recursively Zip Directories

The -r option in the zip command in Linux is used to recursively zip all files and subdirectories within a specified directory.

This is a great option when you need to compress directories while preserving the entire folder structure.

• Main Syntax:

zip -r <archive-name>.zip <directory-to-zip>

• Example:

To recursively zip the opera_project directory and its contents into documents.zip, run:

zip -r documents.zip opera_project

Output

adding: opera_project/
adding: opera_project/opera_project.txt (deflated 25%)

Recursive zipping with the Linux zip command is perfect for compressing directories into zip archives, allowing you to easily handle large files and subdirectories.

This option is ideal for Recursive zipping with the Linux zip command, ensuring that all files and folders are included in the compressed archive.

10. Exclude Unwanted Files from a Zip Archive

The -x option in the zip command in Linux allows you to exclude specific files from being added to the archive.

This is useful when you want to compress a directory but omit certain files, such as temporary files or logs, to keep the archive clean and efficient.

• Main Syntax:

zip -r -x <file-to-exclude> <archive-name>.zip <directory-to-zip>

• Example:

To zip the opera_project directory into documents.zip but exclude *.log files, run:

zip -r -x "*.log" documents.zip opera_project

Output

adding: opera_project/
adding: opera_project/opera_project.txt (deflated 20%)

Using the -x option for excluding specific files from a zip archive helps to streamline the process when you need to avoid including unwanted data.

This is an ideal method for filtering files during compression while ensuring important files like your opera_project.txt remain in the archive.

11. View Zip Archive Details

The -v option in the zip command in Linux provides verbose output while compressing files, displaying detailed information about the files being added to the archive.

This helps track the compression process and confirm what files are included in the archive.

• Main Syntax:

zip -v <archive-name>.zip <file1> <file2> ...

• Example:

To compress the opera_project.txt file and view detailed information about the compression, run:

zip -v documents.zip opera_project.txt

Output

  adding: opera_project.txt (deflated 18%)
  creating: documents.zip
  adding: opera_project.txt (stored 18%)

12. Secure Your ZIP Archive with Password Protection

The -e option allows you to create a password-protected ZIP file, ensuring that only authorized users can access its contents.

This is an essential feature for securing sensitive files or protecting confidential data.

• Main Syntax:

zip -e <archive-name>.zip <file1> <file2> ...

• Example:

To create a password-protected ZIP archive named secure_documents.zip for the opera_project and report.txt files, run:

zip -e secure_documents.zip opera_project report.txt

Output

Enter password: ********
Verify password: ********
  adding: opera_project/ (stored 0%)
  adding: report.txt (deflated 20%)

With the -e option, the ZIP archive is encrypted, requiring a password to extract its contents, which makes it an excellent method for securing sensitive files in a Linux environment.

For those interested in managing visibility and security in Linux, hide files and show hidden files in Ubuntu might be a helpful source.

13. Create Split ZIP Archives

The -s option in the zip command in Linux allows you to split a large ZIP archive into smaller, manageable parts.

This is especially useful when dealing with large files that need to be transferred or stored in segments, particularly when you need to send them via email or upload them to servers with size limits.

• Main Syntax:

zip -s <size> <archive-name>.zip <file1> <file2> ...

Where <size> defines the maximum size of each split archive (e.g., 10m for 10 MB).

• Example:

To create a split archive of the opera_project directory, where each split part is 10 MB, run:

zip -s 10m split_project.zip opera_project

Output

  adding: opera_project/ (stored 0%)
  adding: opera_project/file1.txt (deflated 20%)
  adding: opera_project/subfolder/ (stored 0%)
  creating split_project.zip.z01
  creating split_project.zip.z02

Compressing large files into manageable segments with the -s option in Linux is crucial for efficient file transfer and storage management.

The split archive will be saved in parts, with each part being of the specified size (e.g., 10MB).

Using the zip command in Linux to compress files and directories into split archives helps manage large amounts of data, ensuring that files can be efficiently distributed or backed up in smaller chunks.

How to Create a ZIP Archive Using a GUI in Linux
