Ubuntu: How to Unzip a File using Terminal

If you have a .zip file on your Ubuntu system and you are wondering how to unzip the file using the Terminal (Command Line), well you can make use of the unzip binary.

First thing we need to check if unzip is installed on your Ubuntu system by just typing unzip on on the Terminal Prompt.

# unzip

bash: unzip command not found.

If you get the command not found, well you need to get it installed (this will be the case if you are using a docker image of Ubuntu).

To download and install unzip we will need to make use of the apt-get package manager.

sudo apt-get install unzip

Now we are good to unzip our zip file.

unzip my_zip_file.zip

Note this will extract the contents of the zip file in the current directory.

If you wish to unzip the contents to a specific location then you can make use of the -d parameter.

Example:

unzip my_zip_file.zip -d path/to/the/destination/directory

The best way to know more about the utility is by using the unzip -hh option

Extended Help for UnZip

See the UnZip Manual for more detailed help


UnZip lists and extracts files in zip archives.  The default action is to
extract zipfile entries to the current directory, creating directories as
needed.  With appropriate options, UnZip lists the contents of archives
instead.

Basic unzip command line:
  unzip [-Z] options archive[.zip] [file ...] [-x xfile ...] [-d exdir]

Some examples:
  unzip -l foo.zip        - list files in short format in archive foo.zip

  unzip -t foo            - test the files in archive foo

  unzip -Z foo            - list files using more detailed zipinfo format

  unzip foo               - unzip the contents of foo in current dir

  unzip -a foo            - unzip foo and convert text files to local OS

....
