perldoc -f BuiltinFunction

perldoc -q FAQ Keyword

See below for more description of the switches.

DESCRIPTION

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 the perltoc manpage page.

OPTIONS

-h

Prints out a brief help message.

-v

Describes search for the item in detail (verbosely).

-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 (Unformatted)

-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 performed.

-f perlfunc

The -f option followed by the name of a perl built in function will extract the documentation of this function from the perlfunc manpage .

Example:

perldoc -f sprintf

-q perlfaq-search-regexp

The -q option takes a regular expression as an argument. It will search the question headings in perlfaq[1-9] and print the entries matching the regular expression. Example: perldoc -q shuffle

-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 -oIFor 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 must at least provide a parse_from_file method. For example: perldoc -MPod::Perldoc::ToChecker.

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 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 textsize expects an integer, and you do -w textsize:big , expect trouble.)

You can use -w optionname (without a value) as shorthand for -w optionname:I >. This is presumably useful in cases of on/off features like: -w page_numbering .

You can use a ``='' instead of the ``:'', as in: -w textsize=15 . This might be more (or less) convenient, depending on what shell you use.

-X

Use an index if it is present -- the -X option looks for an entry whose basename matches the name given on the command line in the file $Config{archlib}/pod.idx. The pod.idx file should contain fully qualified filenames, one per line.

PageName|ModuleName|ProgramName

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.

-n some-formatter

Specify replacement for nroff

-r

Recursive search.

-i

Ignore case.

-V

Displays the version of perldoc you're running.
