## NAME
       lwp-request - Simple command line user agent

## SYNOPSIS
       **lwp-request **[**-afPuUsSedvhx**] [**-m _**method_] [**-b _**base_ _URL_] [**-t _**timeout_]
                   [**-i _**if-modified-since_] [**-c _**content-type_]
                   [**-C _**credentials_] [**-p _**proxy-url_] [**-o _**format_] _url_...

## DESCRIPTION
       This program can be used to send requests to WWW servers and your local file system. The
       request content for POST, PUT and PATCH methods is read from stdin.  The content of the
       response is printed on stdout.  Error messages are printed on stderr.  The program returns a
       status value indicating the number of URLs that failed.

       The options are:

### -m <method>
           Set  which method to use for the request.  If this option is not used, then the method is
           derived from the name of the program.

       -f  Force request through, even if the program believes that  the  method  is  illegal.   The
           server might reject the request eventually.

### -b <uri>
           This URI will be used as the base URI for resolving all relative URIs given as argument.

### -t <timeout>
           Set  the  timeout  value  for  the  requests.  The timeout is the amount of time that the
           program will wait for a response from the remote server before  it  fails.   The  default
           unit  for the timeout value is seconds.  You might append "m" or "h" to the timeout value
           to make it minutes or hours, respectively.  The default timeout is '3m', i.e. 3 minutes.

### -i <time>
           Set the If-Modified-Since header in the request. If _time_ is the name of a file,  use  the
           modification  timestamp  for  this file. If _time_ is not a file, it is parsed as a literal
           date. Take a look at [HTTP::Date](https://www.chedong.com/phpMan.php/perldoc/HTTP%3A%3ADate/markdown) for recognized formats.

### -c <content-type>
           Set the Content-Type for the request.  This option is only allowed for requests that take
           a content, i.e. POST, PUT and PATCH.  You can force methods to take content by using  the
           "-f"   option   together   with   "-c".    The   default   Content-Type   for   POST   is
           "application/x-www-form-urlencoded".   The  default  Content-type  for  the   others   is
           "text/plain".

### -p <proxy-url>
           Set  the  proxy  to be used for the requests.  The program also loads proxy settings from
           the environment.  You can disable this with the "-P" option.

       -P  Don't load proxy settings from environment.

### -H <header>
           Send this HTTP header with each request. You can specify several, e.g.:

               lwp-request \
                   -H 'Referer: <http://other.url/>' \
                   -H 'Host: somehost' \
                   <http://this.url/>

       -C <username>:<password>
           Provide credentials for documents that are protected by  Basic  Authentication.   If  the
           document is protected and you did not specify the username and password with this option,
           then you will be prompted to provide these values.

       The following options controls what is displayed by the program:

       -u  Print request method and absolute URL as requests are made.

       -U  Print request headers in addition to request method and absolute URL.

       -s  Print response status code.  This option is always on for HEAD requests.

       -S  Print  response  status  chain.  This  shows redirect and authorization requests that are
           handled by the library.

       -e  Print response headers.  This option is always on for HEAD requests.

       -E  Print response status chain with full response headers.

       -d  Do **not **print the content of the response.

### -o <format>
           Process HTML content in various ways before printing it.  If  the  content  type  of  the
           response  is  not  HTML,  then  this  option has no effect.  The legal format values are;
           "text", "ps", "links", "html" and "dump".

           If you specify the "text" format then the HTML will be formatted as plain "latin1"  text.
           If you specify the "ps" format then it will be formatted as Postscript.

           The "links" format will output all links found in the HTML document.  Relative links will
           be expanded to absolute ones.

           The  "html"  format  will reformat the HTML code and the "dump" format will just dump the
           HTML syntax tree.

           Note that the "HTML-Tree" distribution needs to be installed for this option to work.  In
           addition the "HTML-Format" distribution needs to be installed for "-o text" or "-o ps" to
           work.

       -v  Print the version number of the program and quit.

       -h  Print usage message and quit.

       -a  Set text(ascii) mode for content input and output.  If this option is not  used,  content
           input and output is done in binary mode.

       Because this program is implemented using the LWP library, it will only support the protocols
       that LWP supports.
