To check if the unzip program is installed on your Ubuntu system, follow these steps:

Method 1: Using the Command Line

1. Open a terminal.
2. Run the following command
   • unzip -v

Method 2: Using dpkg

You can check if the unzip package is installed using dpkg:

dpkg -l | grep unzip

• If unzip is installed, you will see its details listed.
• If it is not installed, the command will return nothing.

Method 3: Using which

Another way to check is to see if the unzip binary exists:

which unzip

If not, it will return nothing.

If unzip is installed, this will return the path to the unzip executable, e.g., /usr/bin/unzip.
