2 VMS_specifics
Wget on VMS systems may behave differently in some ways from Wget on other
systems.
The "-b" or "--background" command-line option is ignored on VMS systems.
Other differences involve command-line case, restrictions on directory
and file names, some FTP behavior, and some RMS default parameters.
3 Command-line_case
On non-VAX systems, Wget for VMS enables the following DECC$* run-time
option:
DECC$ARGV_PARSE_STYLE
This way, with extended command parsing enabled ("SET PROCESS
/PARSE_STYLE = EXTENDED"), command-line case is preserved, which
obviates quoting case-sensitive option switches, URLs, and other
parameters.
3 Directory_and_file_names
When the destination for a downloaded file is an ODS2 file system,
excessive dots (".") in file names and directory names generated by
recursive retrieval (which would be illegal in ODS2 directory or file
names) are replaced by underscores ("_"). All tildes ("~") are replaced
by hyphens ("-"), and all "at" signs ("@") are replaced by dollar signs
("$"). Any other invalid characters are replaced by underscores ("_").
Also, case information is lost.
For example, the command:
wget -r "ftp://ftp.xfree86.org/pub/XFree86/3.3.5/binaries/NetBSD-1.3/"
on a UNIX system, should put files into the directory:
./ftp.xfree86.org/pub/XFree86/3.3.5/binaries/NetBSD-1.3/
while on a VMS ODS2 file system, the directory would be:
[.FTP_XFREE86_ORG.PUB.XFREE86.3_3_5.BINARIES.NETBSD-1_3]
When the destination for a downloaded file is an ODS5 file system, the
ODS5-invalid characters "?" and "*" are converted to "!" and "#",
respectively.
On non-VAX systems, Wget for VMS enables the following DECC$* run-time
options:
DECC$EFS_CHARSET
DECC$EFS_CASE_PRESERVE
This way, when the destination for a downloaded file is an ODS5 file
system, multiple dots will be permitted and case will be preserved in
directory and file names, so the previous example directory would be:
[.ftp^.xfree86^.org.pub.XFree86.3^.3^.5.binaries.NetBSD-1^.3]
3 FTP_file_date
Files downloaded using FTP from some servers may get date-time info in
server-local time. Define an environment variable (symbol or logical
name) WGET_TIMEZONE_DIFFERENTIAL (a signed time in seconds) to offset
these file dates.
3 FTP_file_format
By default, when Wget does a binary (Image) FTP transfer, the
destination file is created with fixed-length, 512-byte records. When
Wget does an ASCII FTP transfer, the destination file is created with
Stream_LF format.
In Wget versions before 1.10.1, an FTP destination file was always
created with Stream_LF format.
A command-line option, --ftp-stmlf, forces all FTP destination files to
Stream_LF format, as in Wget versions before 1.10.1.
Add ";type=a" to the end of an FTP URL to specify an ASCII transfer.
Destination files specified using "-O" ("--output-document") are always
created with Stream_LF format.
3 FTP_file_versions
To specify an explicit ";nnn" version number in an FTP URL, escape the
";" as "%3B", or, if the (VMS) FTP server will accept it, use a second
dot. For example, for "file.type;25" use a URL like:
ftp://server/directory/file.type%3B25
or:
ftp://server/directory/file.type.25
3 RMS_default_parameters
For improved I/O speed, when writing a downloaded file, Wget uses these
RMS parameter values by default: BLOCK_COUNT = 127, BUFFER_COUNT = 2,
EXTEND_QUANTITY = 16384.
The user may overide these values by specifying different (non-zero)
values for these parameters using the SET RMS_DEFAULT command.
3 File_attributes
As with many C programs which originated on non-VMS systems, Wget may
make some assumptions about file attributes which can cause some
problems. One example is the "--post-file=FILE" option, which requires
that the "FILE" be in Stream_LF format. (In this case, HTTP 1.0
requires the length of the request to be known, and the method used to
determine the size of the file will fail for Variable-length format
files.)
