       perldoc -v PerlVariable

       See below for more description of the switches.

       perldoc looks up a piece of documentation in .pod format that is
       embedded in the perl installation tree or in a perl script, and
       displays it via "pod2man | nroff -man | $PAGER". (In addition, if
       running under HP-UX, "col -x" will be used.) This is primarily used for
       the documentation for the perl library modules.

       Your system may also have man pages installed for those modules, in
       which case you can probably just use the man(1) command.

       If you are looking for a table of contents to the Perl library modules
       documentation, see the perltoc page.

       -h   Prints out a brief help message.

       -D   Describes search for the item in detail.

       -t   Display docs using plain text converter, instead of nroff. This
            may be faster, but it probably won't look as nice.

       -u   Skip the real Pod formatting, and just show the raw Pod source

       -m module
            Display the entire module: both code and unformatted pod
            documentation.  This may be useful if the docs don't explain a
            function in the detail you need, and you'd like to inspect the
            code directly; perldoc will find the file for you and simply hand
            it off for display.

       -l   Display only the file name of the module found.

       -F   Consider arguments as file names; no search in directories will be
            matching the regular expression.


                 perldoc -q shuffle

       -v perlvar
            The -v option followed by the name of a Perl predefined variable
            will extract the documentation of this variable from perlvar.


                 perldoc -v '$"'
                 perldoc -v @+
                 perldoc -v DATA

       -T   This specifies that the output is not to be sent to a pager, but
            is to be sent right to STDOUT.

       -d destination-filename
            This specifies that the output is to be sent neither to a pager
            nor to STDOUT, but is to be saved to the specified filename.
            Example: "perldoc -oLaTeX -dtextwrapdocs.tex Text::Wrap"

       -o output-formatname
            This specifies that you want Perldoc to try using a Pod-formatting
            class for the output format that you specify.  For example:
            "-oman".  This is actually just a wrapper around the "-M" switch;
            using "-oformatname" just looks for a loadable class by adding
            that format name (with different capitalizations) to the end of
            different classname prefixes.

            For example, "-oLaTeX" currently tries all of the following
            classes: Pod::Perldoc::ToLaTeX Pod::Perldoc::Tolatex
            Pod::Perldoc::ToLatex Pod::Perldoc::ToLATEX Pod::Simple::LaTeX
            Pod::Simple::latex Pod::Simple::Latex Pod::Simple::LATEX
            Pod::LaTeX Pod::latex Pod::Latex Pod::LATEX.

       -M module-name
            This specifies the module that you want to try using for
            formatting the pod.  The class must at least provide a
            "parse_from_file" method.  For example: "perldoc

            You can specify several classes to try by joining them with commas
            or semicolons, as in "-MTk::SuperPod;Tk::Pod".

       -w option:value or -w option
            This specifies an option to call the formatter with.  For example,
            "-w textsize:15" will call "$formatter->textsize(15)" on the
            formatter object before it is used to format the object.  For this
            to be valid, the formatter class must provide such a method, and
            the value you pass should be valid.  (So if "textsize" expects an
            integer, and you do "-w textsize:big", expect trouble.)
            fully qualified filenames, one per line.

       -L language_code
            This allows one to specify the language code for the desired
            language translation. If the "POD2::<language_code>" package isn't
            installed in your system, the switch is ignored.  All available
            translation packages are to be found under the "POD2::" namespace.
            See POD2::IT (or POD2::FR) to see how to create new localized
            "POD2::*" documentation packages and integrate them into

            The item you want to look up.  Nested modules (such as
            "File::Basename") are specified either as "File::Basename" or
            "File/Basename".  You may also give a descriptive name of a page,
            such as "perlfunc".

            For simple names like 'foo', when the normal search fails to find
            a matching page, a search with the "perl" prefix is tried as well.
            So "perldoc intro" is enough to find/render "perlintro.pod".

       -n some-formatter
            Specify replacement for nroff

       -r   Recursive search.

       -i   Ignore case.

       -V   Displays the version of perldoc you're running.

       Because perldoc does not run properly tainted, and is known to have
       security issues, when run as the superuser it will attempt to drop
       privileges by setting the effective and real IDs to nobody's or
       nouser's account, or -2 if unavailable.  If it cannot relinquish its
       privileges, it will not run.

       Any switches in the "PERLDOC" environment variable will be used before
       the command line arguments.

       Useful values for "PERLDOC" include "-oman", "-otext", "-otk", "-ortf",
       "-oxml", and so on, depending on what modules you have on hand; or the
       formatter class may be specified exactly with "-MPod::Perldoc::ToMan"
       or the like.

       "perldoc" also searches directories specified by the "PERL5LIB" (or
       "PERLLIB" if "PERL5LIB" is not defined) and "PATH" environment
       variables.  (The latter is so that embedded pods for executables, such
       as "perldoc" itself, are available.)

       "perldoc" will use, in order of preference, the pager defined in
       "PERLDOC_PAGER", "MANPAGER", or "PAGER" before trying to find a pager
       on its own. ("MANPAGER" is not used if "perldoc" was told to display
