This program can be used to send requests to WWW servers and your
local file system. The request content for POST and PUT
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.
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 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 and PUT. 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
- -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
Don't load proxy settings from environment.
- -H <header>
Send this HTTP header with each request. You can specify several, e.g.:
-H 'Referer: http://other.url/' \
-H 'Host: somehost' \
- -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:
Print request method and absolute URL as requests are made.
Print request headers in addition to request method and absolute URL.
Print response status code. This option is always on for HEAD requests.
Print response status chain. This shows redirect and authorization
requests that are handled by the library.
Print response headers. This option is always on for HEAD requests.
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.
Print the version number of the program and quit.
Print usage message and quit.
Extra debugging output.
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.
