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.
|
|
|
|
|
2010-01-09 18:24:02 -05:00
|
|
|
A command-line option, --ftp-stmlf, forces all FTP destination files to
|
|
|
|
Stream_LF format, as in Wget versions before 1.10.1.
|
2008-04-22 17:48:36 -04:00
|
|
|
|
|
|
|
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
|
2010-01-09 18:24:02 -05:00
|
|
|
files.)
|
