Linux "a2query" Command Line Options and Examples

retrieve runtime configuration from a local Apache 2 HTTP server

a2query is a program designed to retrieve configuration values from a locally available Apache 2 HTTP web server. It was designed to be as robust as possible by returning feasible values even if the Apache 2 syntax validator fails. This program is primarily meant to be used from maintainer scripts.
