说明
a2query is a Debian-specific utility designed to retrieve configuration values from a locally installed Apache2 web server. It provides a robust interface primarily intended for use in maintainer scripts but also useful for system administrators. Arguments for -c, -m, and -s options are compared flexibly, ignoring leading mod_ prefixes and .conf or .load suffixes.
