<H2>DESCRIPTION</H2>
|
|
|
|
|
|
|
|
<B>a2query</B> is a program designed to retrieve configuration values from a locally
|
|
available Apache 2 <FONT SIZE="-1">HTTP</FONT> web server. It was designed to be as robust as possible
|
|
by returning feasible values even if the Apache 2 syntax validator fails.
|
|
<P>
|
|
|
|
This program is primarily meant to be used from maintainer scripts.

|
|
|

|
Returns the Apache 2 ``Module Magic Version'' (<FONT SIZE="-1">API</FONT> version) number, the server was
|
|
compiled with. The returned version does not contain any minor versions which
|
|
are known to be compatible with the major version returned.
|
|
<DT id="2">-c [<I></I><FONT SIZE="-1"><I>CONF</I></FONT><I></I>]<DD>
|
|
|
|
|
|
Checks whether the configuration <I></I><FONT SIZE="-1"><I>CONF</I></FONT><I></I> is enabled. If no argument was given,
|
|
all enabled configuration files are being returned. <I></I><FONT SIZE="-1"><I>CONF</I></FONT><I></I> is compared by
|
|
string comparison by ignoring a leading ``mod_'' prefix and possibly a '.conf' or
|
|
'.load' suffix.
|
|
<DT id="3">-h<DD>
|
|
|
|
|
|

|
|
the same way, as for configuration files queried by the -c switch.
|
|
<DT id="5">-M<DD>
|
|
|
|
|
|
Returns the currently enabled Apache 2 <FONT SIZE="-1">MPM</FONT> (Multi Processing Module).
|
|

|
|
|
|
|
|
Checks whether the module <I></I><FONT SIZE="-1"><I>SITE</I></FONT><I></I> is enabled, The argument is interpreted in
|
|

|
|
<DT id="7">-v<DD>
|
|
|
|
|
|
returns the currently installed Apache 2 <FONT SIZE="-1">HTTP</FONT> server version

<H2>EXIT CODES</H2>
|
|
|
|
|
|
|
|
<B>a2query</B> returns with a zero (0) exit status if the requested operation was
|
|
effectuated successfully and with a non-zero status otherwise. In case of an
|
|
error it leaves with error code 32 if a requested module, site or
|
|
configuration was not found and 33 if a module, site or configuration was
|
|
disabled by a maintainer script. However, exit status 1 is returned if the
|
|
module was not found at all
