apache:version

The command "sudo apache2ctl -v" is used to check the version of the Apache HTTP Server installed on the system.

Here is a breakdown of the command:

• "sudo" is a command in Unix-based systems that allows a user with superuser/administrative privileges to execute a command as another user, typically the root user. It will prompt for the user's password before executing the command.

• "apache2ctl" is a command-line utility used to control and manage the Apache HTTP Server. It provides various options to start, stop, restart, test configuration files, and more.

• "-v" is a command-line option that stands for "version". When used with "apache2ctl", it instructs the utility to display the version of the Apache server currently installed.

By running "sudo apache2ctl -v" in the terminal, you will see the version information of the Apache HTTP Server, including the server version, the build date, the installed modules, and other relevant details.
