149 Wget on VMS systems may behave differently in some ways from Wget on other
152 The "-b" or "--background" command-line option is ignored on VMS systems.
154 Other differences involve command-line case, restrictions on directory
155 and file names, some FTP behavior, and some RMS default parameters.
158 On non-VAX systems, Wget for VMS enables the following DECC$* run-time
160 DECC$ARGV_PARSE_STYLE
162 This way, with extended command parsing enabled ("SET PROCESS
163 /PARSE_STYLE = EXTENDED"), command-line case is preserved, which
164 obviates quoting case-sensitive option switches, URLs, and other
167 3 Directory_and_file_names
168 When the destination for a downloaded file is an ODS2 file system,
169 excessive dots (".") in file names and directory names generated by
170 recursive retrieval (which would be illegal in ODS2 directory or file
171 names) are replaced by underscores ("_"). All tildes ("~") are replaced
172 by hyphens ("-"), and all "at" signs ("@") are replaced by dollar signs
173 ("$"). Any other invalid characters are replaced by underscores ("_").
174 Also, case information is lost.
176 For example, the command:
177 wget -r "ftp://ftp.xfree86.org/pub/XFree86/3.3.5/binaries/NetBSD-1.3/"
179 on a UNIX system, should put files into the directory:
180 ./ftp.xfree86.org/pub/XFree86/3.3.5/binaries/NetBSD-1.3/
182 while on a VMS ODS2 file system, the directory would be:
183 [.FTP_XFREE86_ORG.PUB.XFREE86.3_3_5.BINARIES.NETBSD-1_3]
185 When the destination for a downloaded file is an ODS5 file system, the
186 ODS5-invalid characters "?" and "*" are converted to "!" and "#",
189 On non-VAX systems, Wget for VMS enables the following DECC$* run-time
192 DECC$EFS_CASE_PRESERVE
194 This way, when the destination for a downloaded file is an ODS5 file
195 system, multiple dots will be permitted and case will be preserved in
196 directory and file names, so the previous example directory would be:
197 [.ftp^.xfree86^.org.pub.XFree86.3^.3^.5.binaries.NetBSD-1^.3]
200 Files downloaded using FTP from some servers may get date-time info in
201 server-local time. Define an environment variable (symbol or logical
202 name) WGET_TIMEZONE_DIFFERENTIAL (a signed time in seconds) to offset
206 By default, when Wget does a binary (Image) FTP transfer, the
207 destination file is created with fixed-length, 512-byte records. When
208 Wget does an ASCII FTP transfer, the destination file is created with
211 In Wget versions before 1.10.1, an FTP destination file was always
212 created with Stream_LF format.
214 A new command-line option, --ftp-stmlf, forces all FTP destination
215 files to Stream_LF format, as in Wget versions before 1.10.1.
217 Add ";type=a" to the end of an FTP URL to specify an ASCII transfer.
219 Destination files specified using "-O" ("--output-document") are always
220 created with Stream_LF format.
223 To specify an explicit ";nnn" version number in an FTP URL, escape the
224 ";" as "%3B", or, if the (VMS) FTP server will accept it, use a second
225 dot. For example, for "file.type;25" use a URL like:
226 ftp://server/directory/file.type%3B25
228 ftp://server/directory/file.type.25
230 3 RMS_default_parameters
231 For improved I/O speed, when writing a downloaded file, Wget uses these
232 RMS parameter values by default: BLOCK_COUNT = 127, BUFFER_COUNT = 2,
233 EXTEND_QUANTITY = 16384.
235 The user may overide these values by specifying different (non-zero)
236 values for these parameters using the SET RMS_DEFAULT command.
239 As with many C programs which originated on non-VMS systems, Wget may
240 make some assumptions about file attributes which can cause some
241 problems. One example is the "--post-file=FILE" option, which requires
242 that the "FILE" be in Stream_LF format. (In this case, HTTP 1.0
243 requires the length of the request to be known, and the method used to
244 determine the size of the file will fail for Variable-length format
