Install unzip command

First, open the terminal application. Next, use any one of the following command as per your Linux or Unix variant to install the unzip tool:

Debian/Ubuntu Linux user install unzip

The syntax is as follows using apt-get command:

sudo apt-get install unzip

CentOS/RHEL/Fedora Linux user install unzip

The syntax is as follows using yum command:

sudo yum install unzip

How do I use unzip command on a Linux or Unix like systems?

The syntax is:

unzip zipfilename
unzip zipfilename fileToExtract
unzip [optionz] zipfilename

Extract a zip file named

To use unzip to extract all members of the archive into the current directory and subdirectories below it, creating any subdirectories as necessary, type:
unzip database
Another example:

unzip foo
<pre lang="bash">

Sample outputs:

   creating: etc/
  inflating: etc/afpovertcp.cfg      
  inflating: etc/aliases             
   creating: etc/apache2/
   creating: etc/apache2/extra/
  inflating: etc/apache2/extra/httpd-autoindex.conf  
  inflating: etc/apache2/extra/httpd-dav.conf  
  inflating: etc/apache2/extra/httpd-default.conf  
  inflating: etc/apache2/extra/httpd-info.conf  
  inflating: etc/apache2/extra/httpd-languages.conf  
  inflating: etc/apache2/extra/httpd-manual.conf  
  inflating: etc/apache2/extra/httpd-mpm.conf  
  inflating: etc/sshd_config         
  inflating: etc/sshd_config~previous  
  inflating: etc/syslog.conf         
  inflating: etc/ttys                
 extracting: etc/xtab                
  inflating: etc/zshenv       

To extract all python (*.py) files, enter:
unzip "*.py"
To extract all C source files “*.c”, and “*.h” and a Makefile into the ~/projects/editor directory:

unzip "*.[ch]" Makefile -d ~/projects/editor

Extract all files except bar.txt from zipfile

 unzip -x bar.txt

Extract files into given directory

To extract files into /tmp/data instead of the default current directory, type:

unzip -d /tmp/data
unzip -d /tmp/data pic1.jpg

Sample outputs:

   creating: ../ddd/etc/
  inflating: ../ddd/etc/afpovertcp.cfg  
  inflating: ../ddd/etc/aliases      
   creating: ../ddd/etc/apache2/
   creating: ../ddd/etc/apache2/extra/
  inflating: ../ddd/etc/apache2/extra/httpd-autoindex.conf  
  inflating: ../ddd/etc/apache2/extra/httpd-dav.conf  
  inflating: ../ddd/etc/apache2/extra/httpd-default.conf  

Forcefully overwrite existing files when unzip

unzip -o
unzip -o data.jpg

The -o option will overwrite files WITHOUT prompting. Pass the -n option to never overwrite existing files:

unzip -n
unzip -n data.jpg

List files stored in a zip file on screen

unzip -l
unzip -l | more
unzip -l

Sample outputs:

  -p  extract files to pipe, no messages     -l  list files (short format)
  -f  freshen existing files, create none    -t  test compressed archive data
  -u  update files, create if necessary      -z  display archive comment
  -x  exclude files that follow (in xlist)   -d  extract files into exdir
modifiers:                                   -q  quiet mode (-qq => quieter)
  -n  never overwrite existing files         -a  auto-convert any text files
  -o  overwrite files WITHOUT prompting      -aa treat ALL files as text
  -j  junk paths (do not make directories)   -v  be verbose/print version info
  -C  match filenames case-insensitively     -L  make (some) names lowercase
  -X  restore UID/GID info                   -V  retain VMS version numbers
  -K  keep setuid/setgid/tacky permissions   -M  pipe through "more" pager
Examples (see unzip.txt for more info):
  unzip data1 -x joe   => extract all files except joe from zipfile
  unzip -p foo | more  => send contents of via pipe into program more
