How to unzip a Zip File from the Terminal? 

For the understanding of unzipping the zip file using the command line, use the above-mentioned general syntax. 

Some of the basic usage of the unzip command in Linux have been explained with examples. 

Example 1: List Down the Contents using the unzip Command

Unzip command can be used to list down the contents of the zip archive file. For example, using the zip command, the contents of the “itslinuxfoss.zip” will be displayed:

$ unzip -l itslinuxfoss.zip
Unzip A File In Linux 2

The “l” option of the unzip is used to list down the contents of the compressed zip archive file.

Example 2: Unzip a Single File Using the unzip

To extract the specific single file from the zip archive, follow the general syntax of unzip command. For example, to extract the “itslinuxfoss/myfile5.txt” from “itslinuxfoss.zip”, run the command:

$ unzip itslinuxfoss.zip itslinuxfoss/myfile5.txt
Unzip A File In Linux 3

Example 3: Unzip the Multiple Files Using the unzip

Now extract the multiple files from the “mylinuxfoss.zip” using the unzip command:

$ unzip itslinuxfoss.zip itslinuxfoss/myfile6.txt itslinuxfoss/myfile6.txt
Unzip A File In Linux 4

Example 4: Unzip a Compressed File From Another Directory Using the unzip

To unzip the compressed zip archive located in some other directory, use the “d” option of the unzip command. For example, to unzip the “itslinuxfoss.zip” from the “Downloads” directory, execute the command:

$ unzip itslinuxfoss.zip -d /home/vboxuser/Downloads
Unzip A File In Linux 5

Example 5: Unzip the Entire Zip Archive Using the unzip Command

To unzip the complete zip archive, for example, “itslinuxfoss.zip”, run the command:

$ unzip itslinuxfoss.zip
Unzip A File In Linux 6

Example 6: Unzip All the Zip Archives within the Directory

To unzip all the zip archives within the same directory, simply execute the command:

$ unzip *.zip
Unzip A File In Linux 7

Example 7: Unzip a Zip Archive without Retaining its Structure

To extract the compressed file without retaining the structure of its directory, use the “j” option:

$ unzip -j itslinuxfoss.zip
Unzip A File In Linux 8

Example 8: Overwrite the Existing Files while Unzipping

When the same file is overwritten again, a message for the confirmation of the overwrite is prompted on the screen:

$ unzip itslinuxfoss.zip
Unzip A File In Linux 8

To overwrite the file without displaying the confirmation message, use the “o” option of unzip command:

$ unzip -o itslinuxfoss.zip
Unzip A File In Linux 9

Example 9: Extract a Zip Archive that is Password Protected

Use the “p” option of the unzip command to unzip the password protected zip archive. After using the “p” option, type the “password” and then the compressed file name. For example, to unzip the “itslinuxfoss” protected with a “qwer1234” password, use the command:

$ unzip -p qwer1234 itslinuxfoss.zip
Unzip A File In Linux 10

Example 10: Suppressing the Output Allows to Unzip the Zip Archive

How to Unzip a File in Linux Using the p7zip or 7z?

Another command utility that can be used to unzip the compressed files in Linux is by using the 7z command. The 7z command utility can be installed with the p7zip package, with the command:

$ sudo apt install p7zip-full -y
Unzip A File In Linux 12

After installing the 7z command utility, list down the contents of the zip archive using its “l” option:

$ 7z l itslinuxfoss.zip
Unzip A File In Linux 13

To unzip the contents of the “itslinuxfoss.zip” with the 7z command, use its “x” option:

$ 7z x itslinuxfoss.zip
Unzip A File In Linux 15

How to Unzip a File Using a Python Script?

The Python programming language can also be used to unzip a file in Linux and to use Python programming, create a Python script by opening a file using the nano text editor:

$ nano pyunzip_script.py
Unzip A File In Linux 16

The Python script listed below should be copied and pasted into the newly opened file:

#!/usr/bin/env python3
import sys
from zipfile import PyZipFile
for zip_file in sys.argv[1:]:
    pzf = PyZipFile(zip_file)
    pzf.extractall()
Unzip A File In Linux 17

Using the keyboard shortcuts CTRL+S to save a file and CTRL+X to close the nano text editor, respectively.  Now to unzip the “itslinuxfoss.zip” using the Python script, run the command:

$ python3 pyunzip_script.py itslinuxfoss.zip
Unzip A File In Linux 18

To confirm the successful execution of the Python script, list down the contents of the directory:

$ ls
Unzip A File In Linux 19

The folder of “itslinuxfoss” has successfully extracted using the Python script. 

How to Use a Perl Script to Unzip a File on Linux?

The “Perl Programming Language” is an additional programming language that may be used to unzip a file in Linux.  It can be used similarly to the Python language, first create a new file:

$ nano perlunzip_script.pl
Unzip A File In Linux 20

Copy and paste the below-mentioned Perl script for unzipping a zip archive file:

#!/usr/bin/perl

use strict;
use warnings;

my $zip_file = shift;

unless ($zip_file) {
    die "Usage: $0 <zip_file>\n";
}

unless (-e $zip_file) {
    die "Error: $zip_file not found.\n";
}

my $unzip_command = "unzip $zip_file";
system($unzip_command) == 0 or die "Error while unzipping: $!\n";
print "Successfully extracted $zip_file.\n";
Unzip A File In Linux 21
Unzip A File In Linux 23

Now using the shortcuts of CTRL+S and CTRL+X, save the file and close the nano text editor respectively. Now make the Perl script executable using the command:

$ chmod +x perlunzip_script.pl
Unzip A File In Linux 24

To unzip an “itslinuxfoss.zip” using the Perl script, run the command:

$ ./perlunzip_script.pl itslinuxfoss.zip
Unzip A File In Linux 25

The zip archive file has successfully unzipped with the Perl script. 

These are all many ways to use a terminal or the command-line to unzip a file in Linux. 

Conclusion
