Make sure to verify the download to ensure that the file is complete and not corrupted. A corrupted file can lead to installation issues. Downloading can take a bit of time.

Preparing for Installation

Before running the installer, you need to prepare your system by opening the terminal, navigating to the download directory, and extracting the downloaded file.

Opening the Terminal

The terminal is your gateway to interacting with the CentOS Stream 10 operating system via command-line interface (CLI). You’ll use the terminal to execute commands for installing and configuring IntelliJ IDEA.

Open the terminal application. You can usually find it in the applications menu or by searching for “terminal”.

Once the terminal is open, you are ready to execute commands. Make sure you have the correct user permissions to proceed.

Navigating to the Download Directory

After opening the terminal, navigate to the directory where you saved the downloaded IntelliJ IDEA tar.gz file. The `cd` command is used to change directories.

Use the `cd` command followed by the path to your download directory. For example, if you saved the file in the “Downloads” directory, the command would be:
```
cd Downloads
```

Verify that you are in the correct directory by listing the files using the `ls` command. You should see the IntelliJ IDEA tar.gz file in the list.

Extracting the Downloaded File

The tar.gz file needs to be extracted to a directory where IntelliJ IDEA will be installed. Use the `tar` command to extract the file.

Execute the following command to extract the tar.gz file:
```
tar -xzf ideaIC-*.tar.gz
```
Replace `ideaIC-*.tar.gz` with the actual name of the downloaded file.
The `-xzf` options tell tar to extract (`x`), decompress using gzip (`z`), and specify the file (`f`).

This process will create a new directory with the extracted files. The directory name will typically be `idea-IC-`, where `<version>` is the version number of IntelliJ IDEA.

Installing IntelliJ IDEA

With the file extracted, you can now proceed to install IntelliJ IDEA. This involves navigating to the bin folder within the extracted directory and running the installation script.

Changing Directory to Bin Folder

Navigate to the `bin` directory within the extracted IntelliJ IDEA directory. This directory contains the executable files needed to start IntelliJ IDEA.

Use the `cd` command to navigate to the `bin` directory. For example:
```
cd idea-IC-*/bin
```
Replace `idea-IC-*` with the actual name of the extracted directory.

The `bin` directory contains the `idea.sh` script, which is used to launch IntelliJ IDEA.

Running the Installation Script

Execute the `idea.sh` script to start the installation process. This script will launch the IntelliJ IDEA installation wizard.

Run the following command to execute the installation script:
```
./idea.sh
```
If you encounter a “Permission denied” error, you may need to make the script executable:
```
chmod +x idea.sh
./idea.sh
```

This command starts the IntelliJ IDEA installation wizard, which guides you through the remaining steps.
