pm_which - find installed modules

CONTENTS

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.
