NAME

       pm_which - find installed modules

SYNOPSIS

	   pm_which [ options ] module(s)

	   Returns the path to the given module(s)

   OPTIONS
	   -q, --quiet	   Just print paths
	   -p, --paths	   Just convert the module name into a relative path
	   -a, --all	   Print all paths, not just the first one found
	   -n, --namespace Print all modules in the given namespace
	   -m		   Only print module names, not paths
	   -V		   Show module version
	   -I libpath	   Add a path to search (like perl -I)
	   -d, --dump	   Dump paths that would be searched (@INC by default)
	   -h, --help	   Print this message
	   -v, --version   Print version information
	   -		   Read modules from stdin, one per line

DESCRIPTION

       This tool reports the locations of installed perl modules.

       By default it lists the location of each specified module that would be loaded by require.

OPTION DETAILS

   quiet
       Under quiet mode, module names are suppressed and missing modules are not reported.

       Normal output:

	   $ pm_which Module::One Module::Two Missing::Module
	   Module::One	   - /path/to/Module/One.pm
	   Module::Two	   - /path/to/Module/Two.pm
	   Missing::Module - not found

       Under --quiet:

	   $ pm_which -q Module::One Module::Two Missing::Module
	   /path/to/Module/One.pm
	   /path/to/Module/Two.pm

   paths
       In "paths" mode, each module is simply converted into a relative file path. This is possible even when the module is not installed.

	   $ pm_which -p Missing::Module
	   Missing/Module.pm

   all
       When the "all" switch is specified, all installed modules will be reported, not just the first one. This is useful for determining when
       there is a module installed in multiple locations.

	   $ pm_which -a MyModule
	   /path/to/MyModule.pm
	   /home/me/perl/MyModule.pm

   namespace
       Arguments are taken as namespaces to search under.

	   $ pm_which -n MyModule
	   MyModule	       - /path/to/MyModule.pm
	   MyModule::Foo       - /path/to/MyModule/Foo.pm
	   MyModule::Foo::Bar  - /path/to/MyModule/Foo/Bar.pm

   -m
       Disables printing of module paths. This is only really useful in conjunction with --namespace.

	   $ pm_which -nm MyModule
	   MyModule
	   MyModule::Foo
	   MyModule::Foo::Bar

   -V
       Prints the version of each module, according to ExtUtils::MakeMaker.

	   $ pm_which -V MyModule
	   MyModule - /path/to/MyModule.pm [ 1.00 ]

	   $ pm_which -Vnm MyModule
	   MyModule [ 1.00 ]
	   MyModule::Foo [ 0.01 ]
	   MyModule::Foo::Bar [ undef ]

   dump
       Dumps the paths that would be searched and exits. This is @INC modified by any -I switches.

	   $ pm_which --dump
	   /usr/lib/perl5/site_perl/5.8.6
	   /usr/lib/perl5/vendor_perl/5.8.6
	   ...

	   $ pm_which -I lib --dump -I blib/lib
	   lib
	   blib/lib
	   /usr/lib/perl5/site_perl/5.8.6
	   ...

   version
       Prints the version number of the script, plus the version and path of Module::Util that was loaded.

EXIT CODES

       o   0 - Everything was OK

       o   1 - Initialisation failed (bad switches?)

       o   2 - Some modules were not installed

SEE ALSO

       This utility comes with Module::Util.
