7z: command not found

It seems like the 7z command is not found on your system. This error usually occurs when the 7-Zip package is not installed or not added to the system's PATH variable. To resolve this issue, you can try the following steps:

1. Install the 7-Zip package if it is not already installed on your system. You can download it from the official website (www.7-zip.org).

2. Make sure the 7-Zip installation directory is added to the system's PATH variable. This allows the system to locate the 7z command when you execute it from the command line.

- On Windows:
- Open the Control Panel and go to System > Advanced system settings.
- Click on the "Environment Variables" button.
- In the "System variables" section, scroll down and double-click on the "Path" variable.
- Add the path to the 7-Zip installation directory (e.g., C:\Program Files\7-Zip) at the end of the "Variable value" field.
- Click OK to save the changes.

- On Linux:
- Open a terminal and run the following command to edit the ~/.bashrc file:

       nano ~/.bashrc

- Add the following line at the end of the file, replacing "/path/to/7zip" with the actual path to your 7-Zip installation directory:

       export PATH="/path/to/7zip:$PATH"

- Save the changes (Ctrl+O) and exit (Ctrl+X).
- Run the following command to apply the changes to your current session:

       source ~/.bashrc

Once you have completed these steps, try running the 7z command again in your terminal. It should now be recognized and executed without any errors.
