Bash - Check internet connection

There are multiple ways to check whether or not you got internet connection. The most reliable way that I found is to use the following code.

# Check for internet connection.
if wget -q --spider "http://google.com"; then
    echo "Success, got internet connection!"
else
    echo "Error: No internet connection!"
fi

Output

Success, got internet connection!

Bash, Linux
