a2query: Check if a specific module is installed.
$ sudo a2query -m ${module_name}
try on your machine
The command "sudo a2query -m ${module_name}" is used in Linux systems to query the Apache web server modules.
Here's what each component of the command means:
- "sudo": It is a command that allows users to run programs with the security privileges of another user, typically the superuser (root).
- "a2query": This is a utility command used in Apache web server installations to query various information about Apache modules, sites, and configuration files.
- "-m": It is an option/flag that indicates that we want to query a specific module.
- "${module_name}": It is a placeholder indicating that you need to replace it with the name of the module you want to query. You should replace "${module_name}" with the actual name of the module you are interested in.
For example, if you want to query the status of the "rewrite" module, you would run the command as follows: sudo a2query -m rewrite
This command will then give you information about whether the "rewrite" module is enabled or not in your Apache web server configuration.

never run a command you are not sure if it is safe.
