140 | .SH "DESCRIPTION" |
141 | .IX Header "DESCRIPTION" |
142 | This program can be used to send requests to \s-1WWW\s0 servers and your |
143 | local file system. The request content for \s-1POST\s0 and \s-1PUT\s0 |
144 | methods is read from stdin. The content of the response is printed on |
145 | stdout. Error messages are printed on stderr. The program returns a |
146 | status value indicating the number of URLs that failed. |
147 | .PP |
148 | The options are: |
149 | .IP "\-m <method>" 4 |
150 | .IX Item "-m <method>" |
151 | Set which method to use for the request. If this option is not used, |
152 | then the method is derived from the name of the program. |
153 | .IP "\-f" 4 |
154 | .IX Item "-f" |
155 | Force request through, even if the program believes that the method is |
156 | illegal. The server might reject the request eventually. |
157 | .IP "\-b <uri>" 4 |
158 | .IX Item "-b <uri>" |
159 | This \s-1URI\s0 will be used as the base \s-1URI\s0 for resolving all relative URIs |
160 | given as argument. |
161 | .IP "\-t <timeout>" 4 |
162 | .IX Item "-t <timeout>" |
163 | Set the timeout value for the requests. The timeout is the amount of |
164 | time that the program will wait for a response from the remote server |
165 | before it fails. The default unit for the timeout value is seconds. |
166 | You might append \*(L"m\*(R" or \*(L"h\*(R" to the timeout value to make it minutes or |
167 | hours, respectively. The default timeout is '3m', i.e. 3 minutes. |
168 | .IP "\-i <time>" 4 |
169 | .IX Item "-i <time>" |
170 | Set the If-Modified-Since header in the request. If \fItime\fR is the |
171 | name of a file, use the modification timestamp for this file. If |
172 | \&\fItime\fR is not a file, it is parsed as a literal date. Take a look at |
173 | HTTP::Date for recognized formats. |
174 | .IP "\-c <content\-type>" 4 |
175 | .IX Item "-c <content-type>" |
176 | Set the Content-Type for the request. This option is only allowed for |
177 | requests that take a content, i.e. \s-1POST\s0 and \s-1PUT\s0. You can |
178 | force methods to take content by using the \f(CW\*(C`\-f\*(C'\fR option together with |
179 | \&\f(CW\*(C`\-c\*(C'\fR. The default Content-Type for \s-1POST\s0 is |
180 | \&\f(CW\*(C`application/x\-www\-form\-urlencoded\*(C'\fR. The default Content-type for |
181 | the others is \f(CW\*(C`text/plain\*(C'\fR. |
182 | .IP "\-p <proxy\-url>" 4 |
183 | .IX Item "-p <proxy-url>" |
184 | Set the proxy to be used for the requests. The program also loads |
185 | proxy settings from the environment. You can disable this with the |
186 | \&\f(CW\*(C`\-P\*(C'\fR option. |
187 | .IP "\-P" 4 |
188 | .IX Item "-P" |
189 | Don't load proxy settings from environment. |
190 | .IP "\-H <header>" 4 |
191 | .IX Item "-H <header>" |
192 | Send this \s-1HTTP\s0 header with each request. You can specify several, e.g.: |
193 | .Sp |
194 | .Vb 4 |
195 | \& lwp\-request \e |
196 | \& \-H 'Referer: http://other.url/' \e |
197 | \& \-H 'Host: somehost' \e |
198 | \& http://this.url/ |
199 | .Ve |
200 | .IP "\-C <username>:<password>" 4 |
201 | .IX Item "-C <username>:<password>" |
202 | Provide credentials for documents that are protected by Basic |
203 | Authentication. If the document is protected and you did not specify |
204 | the username and password with this option, then you will be prompted |
205 | to provide these values. |
206 | .PP |
207 | The following options controls what is displayed by the program: |
208 | .IP "\-u" 4 |
209 | .IX Item "-u" |
210 | Print request method and absolute \s-1URL\s0 as requests are made. |
211 | .IP "\-U" 4 |
212 | .IX Item "-U" |
213 | Print request headers in addition to request method and absolute \s-1URL\s0. |
214 | .IP "\-s" 4 |
215 | .IX Item "-s" |
216 | Print response status code. This option is always on for \s-1HEAD\s0 requests. |
217 | .IP "\-S" 4 |
218 | .IX Item "-S" |
219 | Print response status chain. This shows redirect and authorization |
220 | requests that are handled by the library. |
221 | .IP "\-e" 4 |
222 | .IX Item "-e" |
223 | Print response headers. This option is always on for \s-1HEAD\s0 requests. |
224 | .IP "\-d" 4 |
225 | .IX Item "-d" |
226 | Do \fBnot\fR print the content of the response. |
227 | .IP "\-o <format>" 4 |
228 | .IX Item "-o <format>" |
229 | Process \s-1HTML\s0 content in various ways before printing it. If the |
230 | content type of the response is not \s-1HTML\s0, then this option has no |
231 | effect. The legal format values are; \fItext\fR, \fIps\fR, \fIlinks\fR, |
232 | \&\fIhtml\fR and \fIdump\fR. |
233 | .Sp |
234 | If you specify the \fItext\fR format then the \s-1HTML\s0 will be formatted as |
235 | plain latin1 text. If you specify the \fIps\fR format then it will be |
236 | formatted as Postscript. |
237 | .Sp |
238 | The \fIlinks\fR format will output all links found in the \s-1HTML\s0 document. |
239 | Relative links will be expanded to absolute ones. |
240 | .Sp |
241 | The \fIhtml\fR format will reformat the \s-1HTML\s0 code and the \fIdump\fR format |
242 | will just dump the \s-1HTML\s0 syntax tree. |
243 | .Sp |
244 | Note that the \f(CW\*(C`HTML\-Tree\*(C'\fR distribution needs to be installed for this |
245 | option to work. In addition the \f(CW\*(C`HTML\-Format\*(C'\fR distribution needs to |
246 | be installed for \fI\-o text\fR or \fI\-o ps\fR to work. |
247 | .IP "\-v" 4 |
248 | .IX Item "-v" |
249 | Print the version number of the program and quit. |
250 | .IP "\-h" 4 |
251 | .IX Item "-h" |
252 | Print usage message and quit. |
253 | .IP "\-a" 4 |
254 | .IX Item "-a" |
255 | Set text(ascii) mode for content input and output. If this option is not |
256 | used, content input and output is done in binary mode. |
257 | .PP |
258 | Because this program is implemented using the \s-1LWP\s0 library, it will |
259 | only support the protocols that \s-1LWP\s0 supports. |
