How to Zip and Unzip Files in Linux
zip and unzip are popular command-line utilities for compressing and extracting files and directories on Linux systems. zip combines multiple files and directories into a single compressed archive, saving storage space and simplifying file management. unzip extracts the archived contents when needed.
This article explains how to install Linux's zip and unzip utilities to compress files, archive directories, and extract the archived contents.
Prerequisites
Before you begin, you need to:
- Have access to a Linux instance as a non-root sudo user.
Install Zip and Unzip in Linux
The zip and unzip utilities are available through the default package managers on most Linux distributions. Follow the steps below to install both tools using the package manager that matches your distribution.
Follow the steps below to install zip and unzip on Debian-based distributions.
Update the
aptpackage index.CONSOLEInstall

Zip Files in Linux
The zip command to create a .zip archive file that reduces file size and simplifies storage or file sharing.
zip Command Syntax
The zip command uses the following syntax.
Where,
[OPTIONS]modify the command behavior. These are optional. The next section discusses and demonstrates some important options.[COMPRESSED_FILENAME]is the name of the file that the command should create after archiving the files.[FILES/DIRS TO COMPRESS]is the list of files or directories you want to archive.
zip Command Usage
Compress a single file into a
.ziparchive.CONSOLEThe above command creates an archive named
archive-name.zipthat containsfile1.txt.Add multiple files to a new or existing archive.
CONSOLEThe above command adds the listed files to
archive-name.zip. If the archive doesn’t exist, it creates a new one. If it exists, it updates the archive with the specified files.Set the compression level. Use
-0to speed up the zip process without compression. Use-9to compress the file as much as possible.CONSOLEUse the
-Poption to set a password on a zip archive. Password-protecting archives can help secure sensitive files during storage or transfer.CONSOLEThe above command creates an
archive-name.zipfile containingfile4.txt, protected by the passwordyour_password.Use the
-xflag to exclude specific files from the archive. This is useful when compressing multiple files using a wildcard pattern and you want to skip specific files.CONSOLEThe above command adds all
.txtfiles in the directory to the archive exceptsecret.txt.Use the
-uflag to update files in the archive only if the source file is newer.CONSOLEThe above command updates
updatedfile.txtin the archive if the local version has changed since the last zip.Use the
-vflag to view detailed output while compressing files. The verbose output shows the filename, compression method, and size for each file added to the archive.CONSOLE
Unzip Files in Linux
Use the unzip command to extract files from a .zip archive. You can extract all files, target specific files, or list the zipped files.
unzip Command Syntax
The unzip command uses the following syntax.
Where,
[OPTIONS]modify how the contents are extracted. This is optional. The most important options are covered in the next section.[ZIP_FILENAME]is the.zipfile you want to extract entirely or some of its files.[MEMBER FILES/DIRS]are files or directories within the archive to extract. If omitted, the command extracts all files.
unzip Command Usage
Run the unzip command followed by the archive name to extract all files into the working directory.
CONSOLESpecify the filename after the archive name to extract only that file instead of the full archive.
CONSOLEThe above command extracts only
file1.txtfrom the archive and puts it into the working directory.Use the
-dflag to define the destination path where you want the files to be extracted. This is helpful when you want to keep extracted files organized.CONSOLEThe above command extracts all files from the archive into the
/path/to/destinationdirectory.Use the
-lflag to preview all files inside the archive. This option lets you inspect the archive contents before extracting.CONSOLEList multiple filenames after the archive name to extract only those files from the archive.
CONSOLEThe above command extracts
file1.txtandupdatedfile.txtfrom the archive and puts them into the working directory.Use the
-oflag to overwrite files that already exist in the destination without prompting. Overwriting files automatically is useful when scripting or automating the extraction process.CONSOLEThe above command extracts all files from
archive-name.zipand replaces any existing files with the same names without asking for confirmation.Use the
-nflag to skip files already present in the destination. Skipping existing files prevents overwriting.CONSOLEThe above command extracts files from
archive-name.zipbut skips any files that already exist in the destination directory.Use the
-vflag to view detailed output during extraction. This includes file names, sizes, and timestamps for each extracted file.CONSOLE
Zip a Directory
You can archive entire directories into a single .zip file to simplify backups, organize project files, or reduce storage usage.
Use the
zipcommand with the-rflag to compress a directory and include all its files and subdirectories.CONSOLEThe above command creates an archive named
archive-name.zipcontaining everything insidedirectory-name, including nested folders.Use the
-xflag to exclude specific files, file types, or folders during compression. This helps reduce archive size and avoids including unnecessary files.CONSOLEThe above command compresses the
directory-namebut skips all.logand.tmpfiles and the entirecachefolder..List multiple directories after the archive name to combine them into a single zip file.
CONSOLEUse a single dot
.to reference the working directory and compress all its contents.CONSOLE
Unzip a Directory
You can extract a .zip archive that contains an entire folder hierarchy, including subdirectories and nested files. Extracting complete folder structures is helpful when restoring backups, deploying packaged projects, or accessing compressed folders shared between systems.
Use the
unzipcommand followed by the archive name to extract the full directory structure into your working directory.CONSOLEUse the
-dflag to extract the archive into a specific location. This helps keep extracted files organized when working with multiple archives.CONSOLEThe above command extracts the entire directory structure into
/path/to/destination.Use the
-oflag to automatically overwrite the existing files and directories in the target location.CONSOLEUse the
-nflag to skip overwriting existing files or directories.CONSOLEThe above command extracts everything from
archive-name.zipbut leaves existing files and folders untouched in the destination directory.
Conclusion
You have installed the zip and unzip utilities on your Linux system. These utilities allow you to compress individual files, archive entire directories, and extract files or full folder structures from .zip archives. For additional options and advanced usage details, refer to the Info-ZIP documentation.
