if command I have done page using my english. Why ? If has used so often like programlanguage if. If command is different. Same situation with ex. case.

Big idea is to understand that everyline is commandline = works same way even command is builtin if, case, ... or something else like date, ls, rm, ...
- filename generation
- pipe
- io-redirection
- argument delimeter !!! (ex. if ...)
- ...

Example

Code:

ls * 
echo *
if cp x y 2>/dev/null ; then
   print ok
else
   print not so good
fi

I'm sure, you get other links also.

uri::url

URI::URL(3)						User Contributed Perl Documentation					       URI::URL(3)

NAME

       URI::URL - Uniform Resource Locators

SYNOPSIS

	$u1 = URI::URL->new($str, $base);
	$u2 = $u1->abs;

DESCRIPTION

       This module is provided for backwards compatibility with modules that depend on the interface provided by the "URI::URL" class that used to
       be distributed with the libwww-perl library.

       The following differences exist compared to the "URI" class interface:

       o  The URI::URL module exports the url() function as an alternate constructor interface.

       o  The constructor takes an optional $base argument.  The "URI::URL" class is a subclass of "URI::WithBase".

       o  The URI::URL->newlocal class method is the same as URI::file->new_abs.

       o  URI::URL::strict(1)

       o  $url->print_on method

       o  $url->crack method

       o  $url->full_path: same as ($uri->abs_path || "/")

       o  $url->netloc: same as $uri->authority

       o  $url->epath, $url->equery: same as $uri->path, $uri->query

       o  $url->path and $url->query pass unescaped strings.

       o  $url->path_components: same as $uri->path_segments (if you don't consider path segment parameters)

       o  $url->params and $url->eparams methods

       o  $url->base method.  See URI::WithBase.

       o  $url->abs and $url->rel have an optional $base argument.  See URI::WithBase.

       o  $url->frag: same as $uri->fragment

       o  $url->keywords: same as $uri->query_keywords

       o  $url->localpath and friends map to $uri->file.

       o  $url->address and $url->encoded822addr: same as $uri->to for mailto URI

       o  $url->groupart method for news URI

       o  $url->article: same as $uri->message
