NAME
perldoc - Look up Perl documentation in pod format.
SYNOPSIS

Name|ProgramName
perldoc -f BuiltinFunction
perldoc -q FAQ Keyword
DESCRIPTION
perldoc looks up a piece of documentation in .pod format that is embed-
ded in the perl installation tree or in a perl script, and displays it
via "pod2man | nroff -man | $PAGER". (In addition, if running under
HP-UX, "col -x" will be used.) This is primarily used for the documen-
tation for the perl library modules.
Your system may also have man pages installed for those modules, in
which case you can probably just use the man(1) command.
If you are looking for a table of contents to the Perl library modules
documentation, see the perltoc page.
OPTIONS
-h help
Prints out a brief help message.
-v verbose
Describes search for the item in detail.
-t text output
Display docs using plain text converter, instead of nroff. This
may be faster, but it won't look as nice.
-u unformatted
Find docs only; skip reformatting by pod2*
-m module
Display the entire module: both code and unformatted pod documen-
tation. This may be useful if the docs don't explain a function
in the detail you need, and you'd like to inspect the code
directly; perldoc will find the file for you and simply hand it
off for display.
-l file name only
Display the file name of the module found.
-F file names
Consider arguments as file names, no search in directories will be
performed.
-f perlfunc
The -f option followed by the name of a perl built in function
will extract the documentation of this function from perlfunc.
-q perlfaq
The -q option takes a regular expression as an argument. It will
search the question headings in perlfaq[1-9] and print the entries
matching the regular expression.
-X use an index if present
The -X option looks for an entry whose basename matches the name
given on the command line in the file "$Config{archlib}/pod.idx".
The pod.idx file should contain fully qualified filenames, one per
line.
-U run insecurely
Because perldoc does not run properly tainted, and is known to
have security issues, it will not normally execute as the supe-
ruser. If you use the -U flag, it will do so, but only after set-
ting 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.
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".
ENVIRONMENT
Any switches in the "PERLDOC" environment variable will be used before
the command line arguments. "perldoc" also searches directories speci-
fied 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 plain text or
unformatted pod.)
One useful value for "PERLDOC_PAGER" is "less -+C -E".
VERSION
This is perldoc v2.03.
