Thank you for your response vbe :-)

so I have

printf "checking for hidden modules: "
for mm in /sys/module/*; do 
   if test -d ${mm}/sections; then 
      MOD="$(basename ${mm})"; 
      lsmod | grep -E "^${MOD}" > /dev/null || printf "[found hidden module] \n${MOD}\n"; 

which works as expected. Problem is that:
1) if it doesn't find any modules, i cant figure out with this particular command how to make it say [ok] insted of
[found hidden module]
2) if it doesnt find any modules, it doesn't return a new line. Which would be solved also if I could figure out 1) !

Apache2::Module - Perl API for creating and working with Apache modules Synopsis use Apache2::Module (); #Define a configuration directive my @directives = ( { name => 'MyDirective', } ); Apache2::Module::add(__PACKAGE__, @directives); # iterate over the whole module list for (my $modp = Apache2::Module::top_module(); $modp; $modp = $modp->next) { my $name = $modp->name; my $index = $modp->module_index; my $ap_api_major_version = $modp->ap_api_major_version; my $ap_api_minor_version = $modp->ap_api_minor_version; my $commands = $modp->cmds; } # find a specific module my $module = Apache2::Module::find_linked_module('mod_ssl.c'); # remove a specific module $module->remove_loaded_module(); # access module configuration from a directive sub MyDirective { my ($self, $parms, $args) = @_; my $srv_cfg = Apache2::Module::get_config($self, $parms->server); [...] } # test if an Apache module is loaded if (Apache2::Module::loaded('mod_ssl.c')) { [...] } # test if a Perl module is loaded if (Apache2::Module::loaded('Apache2::Status')) { [...] } Description "Apache2::Module" provides the Perl API for creating and working with Apache modules See Apache Server Configuration Customization in Perl. API
"Apache2::Module" provides the following functions and/or methods: "add" Add a module's custom configuration directive to Apache. Apache2::Module::add($package, $cmds); arg1: $package ( string ) the package of the module to add arg2: $cmds ( ARRAY of HASH refs ) the list of configuration directives to add ret: no return value since: 2.0.00 See also Apache Server Configuration Customization in Perl. "ap_api_major_version" Get the httpd API version this module was build against, not the module's version. $major_version = $module->ap_api_major_version(); obj: $module ( "Apache2::Module object" ) ret: $major_version ( integer ) since: 2.0.00 This methid is used to check that module is compatible with this version of the server before loading it. "ap_api_minor_version" Get the module API minor version. $minor_version = $module->ap_api_minor_version(); obj: $module ( "Apache2::Module object" ) ret: $minor_version ( integer ) since: 2.0.00 "ap_api_minor_version()" provides API feature milestones. It's not checked during module init. "cmds" Get the "Apache2::Command" object, describing all of the directives this module defines. $command = $module->cmds(); obj: $module ( "Apache2::Module object" ) ret: $command ( "Apache2::Command object" ) since: 2.0.00 "get_config" Retrieve a module's configuration. Used by configuration directives. $cfg = Apache2::Module::get_config($class, $server, $dir_config); $cfg = Apache2::Module::get_config($class, $server); $cfg = $self->get_config($server, $dir_config); $cfg = $self->get_config($server); obj: $module ( "Apache2::Module object" ) arg1: $class ( string ) The Perl package this configuration is for arg2: $server ( "Apache2::ServerRec object" ) The current server, typically "$r->server" or "$parms->server". opt arg3: $dir_config ( "Apache2::ConfVector object" ) By default, the configuration returned is the server level one. To retrieve the per directory configuration, use "$r->per_dir_config" as a last argument. ret: $cfg (HASH reference) A reference to the hash holding the module configuration data. since: 2.0.00 See also Apache Server Configuration Customization in Perl. "find_linked_module" Find a module based on the name of the module $module = Apache2::Module::find_linked_module($name); arg1: $name ( string ) The name of the module ending in ".c" ret: $module ( "Apache2::Module object" ) The module object if found, "undef" otherwise. since: 2.0.00 For example: my $module = Apache2::Module::find_linked_module('mod_ssl.c'); "loaded" Determine if a certain module is loaded $loaded = Apache2::Module::loaded($module); name: $module ( string ) The name of the module to search for. If $module ends with ".c", search all the modules, statically compiled and dynamically loaded. If $module ends with ".so", search only the dynamically loaded modules. If $module doesn't contain a ".", search the loaded Perl modules (checks %INC). ret: $loaded ( boolean ) Returns true if the module is loaded, false otherwise. since: 2.0.00 For example, to test if this server supports ssl: if (Apache2::Module::loaded('mod_ssl.c')) { [...] } To test is this server dynamically loaded mod_perl: if (Apache2::Module::loaded('')) { [...] } To test if "Apache2::Status" is loaded: if (Apache2::Module::loaded('Apache2::Status')) { [...] } "module_index" Get the index to this modules structures in config vectors. $index = $module->module_index(); obj: $module ( "Apache2::Module object" ) ret: $index ( integer ) since: 2.0.00 "name" Get the name of the module's .c file $name = $module->name(); obj: $module ( "Apache2::Module object" ) ret: $name ( string ) since: 2.0.00 For example a mod_perl module, will return: mod_perl.c. "next" Get the next module in the list, "undef" if this is the last module in the list. $next_module = $module->next(); obj: $module ( "Apache2::Module object" ) ret: $next_module ( "Apache2::Module object" ) since: 2.0.00 "remove_loaded_module" Remove a module from the list of loaded modules permanently. $module->remove_loaded_module(); obj: $module ( "Apache2::Module object" ) ret: no return value since: 2.0.00 "top_module" Returns the first module in the module list. Useful to start a module iteration. $module = Apache2::Module::top_module(); ret: $module ( "Apache2::Module object" ) since: 2.0.00 See Also mod_perl 2.0 documentation.
