(In addition, if running under HP-UX, -C<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 L<perltoc> page. - -=head1 OPTIONS - -=over 5 - -=item B<-h> - -Prints out a brief B<h>elp message. - -=item B<-D> - -B<D>escribes search for the item in B<d>etail. - -=item B<-t> - -Display docs using plain B<t>ext converter, instead of nroff. This may be faster, -but it probably won't look as nice. - -=item B<-u> - -Skip the real Pod formatting, and just show the raw Pod source (B<U>nformatted) - -=item B<-m> I<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. - -=item B<-l> - -Display onB<l>y the file name of the module found. - -=item B<-F> - -Consider arguments as file names; no search in directories will be performed. - -=item B<-f> I<perlfunc> - -The B<-f> option followed by the name of a perl built-in function will -extract the documentation of this function from L<perlfunc>. - -Example: - - perldoc -f sprintf - - -=item B<-q> I<perlfaq-search-regexp> - -The B<-q> option takes a regular expression as an argument. It will search -the B<q>uestion headings in perlfaq[1-9] and print the entries matching -the regular expression. - -Example: - - perldoc -q shuffle - - -=item B<-v> I<perlvar> - -The B<-v> option followed by the name of a Perl predefined variable will -extract the documentation of this variable from L<perlvar>. - -Examples: - - perldoc -v '$"' - perldoc -v @+ - perldoc -v DATA - - -=item B<-T> - -This specifies that the output is not to be sent to a pager, but is to -be sent right to STDOUT. - -=item B<-d> I<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: -C<perldoc -oLaTeX -dtextwrapdocs.tex Text::Wrap> - -=item B<-o> I<output-formatname> - -This specifies that you want Perldoc to try using a Pod-formatting -class for the output format that you specify. For example: -C<-oman>. This is actually just a wrapper around the C<-M> switch; -using C<-oI<formatname>> just looks for a loadable class by adding -that format name (with different capitalizations) to the end of -different classname prefixes. - -For example, C<-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. - -=item B<-M> I<module-name> - -This specifies the module that you want to try using for formatting the -pod. The class must at least provide a C<parse_from_file> method. -For example: C<perldoc -MPod::Perldoc::ToChecker>. - -You can specify several classes to try by joining them with commas -or semicolons, as in C<-MTk::SuperPod;Tk::Pod>. - -=item B<-w> I<option:value> or B<-w> I<option> - -This specifies an option to call the formatter B<w>ith. For example, -C<-w textsize:15> will call -C<< $formatter->textsize(15) >> on the formatter object before it is -used to format the object. For this to be valid, the formatter class -must provide such a method, and the value you pass should be valid. -(So if C<textsize> expects an integer, and you do C<-w textsize:big>, -expect trouble.) - -You can use C<-w optionname> (without a value) as shorthand for -C<-w optionname:I<TRUE>>. This is presumably useful in cases of on/off -features like: C<-w page_numbering>. - -You can use an "=" instead of the ":", as in: C<-w textsize=15>. This -might be more (or less) convenient, depending on what shell you use. - -=item B<-X> - -Use an index if it is present. The B<-X> option looks for an entry -whose basename matches the name given on the command line in the file -C<$Config{archlib}/pod.idx>. The F<pod.idx> file should contain fully -qualified filenames, one per line. - -=item B<-L> I<language_code> - -This allows one to specify the I<language code> for the desired language -translation. If the C<POD2::E<lt>language_codeE<gt>> package isn't -installed in your system, the switch is ignored. -All available translation packages are to be found under the C<POD2::> -namespace. See L<POD2::IT> (or L<POD2::FR>) to see how to create new -localized C<POD2::*> documentation packages and integrate them into -L<Pod::Perldoc>. - -=item B<PageName|ModuleName|ProgramName> - -The item you want to look up. Nested modules (such as C<File::Basename>) -are specified either as C<File::Basename> or C<File/Basename>. You may also -give a descriptive name of a page, such as C<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". - -=item B<-n> I<some-formatter> - -Specify replacement for nroff - -=item B<-r> - -Recursive search. - -=item B<-i> - -Ignore case. - -=item B<-V> - -Displays the version of perldoc you're running. - -=back - - - -=head1 SECURITY - -Because B<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. - - -=head1 ENVIRONMENT - -Any switches in the C<PERLDOC> environment variable will be used before the -command line arguments. - -Useful values for C<PERLDOC> include C<-oman>, C<-otext>, C<-otk>, C<-ortf>, -C<-oxml>, and so on, depending on what modules you have on hand; or -the formatter class may be specified exactly with C<-MPod::Perldoc::ToMan> -or the like. - -C<perldoc> also searches directories -specified by the C<PERL5LIB> (or C<PERLLIB> if C<PERL5LIB> is not -defined) and C<PATH> environment variables. -(The latter is so that embedded pods for executables, such as -C<perldoc> itself, are available.) - -C<perldoc> will use, in order of preference, the pager defined in -C<PERLDOC_PAGER>, C<MANPAGER>, or C<PAGER> before trying to find a pager -on its own. (C<MANPAGER> is not used if C<perldoc> was told to display -plain text or unformatted pod.) - -One useful value for C<PERLDOC_PAGER> is C<less -+C -E>. - -Having PERLDOCDEBUG set to a positive integer will make perldoc emit -even more descriptive output than the C<-v> switch does; the higher the -number, the more it emits. - - -=head1 CHANGES - -Up to 3.14_05, the switch B<-v> was used to produce verbose -messages of B<perldoc> operation, which is now enabled by B<-D>. - -=head1 SEE ALSO - -L<perlpod>, L<Pod::Perldoc> - -=head1 AUTHOR - -Current maintainer: Adriano R.
