Final answer:
To check the NGINX version in Linux, open a terminal and use the command 'nginx -v' for basic version information or 'nginx -V' for detailed information. If necessary, include 'sudo' for proper privileges.
Step-by-step explanation:
To check the NGINX version on Linux, you need to open a terminal window and enter a specific command. The standard command to check the version is:
nginx -v
This command will show you the installed version of NGINX without starting or stopping the service. If you have sudo privileges or if the nginx command is not in your PATH, you might need to run:
sudo nginx -v
Additionally, for more detailed version information including configuration options, you can use:
nginx -V
Remember that case matters in Linux, so be sure to use the capital 'V' for the detailed output. Following these steps properly will provide you with the NGINX version currently installed on your Linux system.
