 I need to investigate further to see if this change was somehow
 intentional (though I can't imagine what the reasoning would be); if I

One reason to keep the current behavior is to retain all of the existing

previous one. However, I think that only makes sense if wget is comparing
the new content with what is already on disk.

OK. Here's some insight: wget is essentially a web browser. If the URL
starts with http, then wget sees the exact same content as Internet
Explorer, Firefox, and Opera (except in cases where the server customizes
its content to the user agent - in those cases you may have to tweak the
user agent to see the same content).

 

If the files are visible to FTP, then try using wget with a URL starting
with ftp instead.  Otherwise, if you want to mirror the files as they
appear on the server, you will have to use something like scp to transfer
the files directly from Server A to Server B.

OK. I'm responding to the chain and not Hrvoje's expression of pain. :-)

What if we changed the semantics of --no-clobber so the user could specify
the behavior? I'm thinking it could accept the following strings:
- after: append a number after the file name (current behavior)
- before: insert a number before the suffix
- new: change name of new file (current behavior)
- old: change name of old file

With this scheme --no-clobber becomes equivalent to --no-clobber=after,new.
If I want to change where the number appears in the file name or have the
old file renamed then I can specify the behavior I want on the command line
(or in .wgetrc). I think I would change my default to
--no-clobber=before,old.

I think it would be useful to have semantics in .wgetrc where I specify what
I want my --no-clobber default to be without that meaning I want
--no-clobber processing on each invocation. It would be nice if I could say
that I want my default to be before,old, but to only have that apply when
I specify --no-clobber on the command line.

Back to the painful point at the start of this note, I think we treat
.tar.gz as a suffix and if --no-clobber=before is specified, the file name
becomes .1.tar.gz.

No, you can only get wget to compare a file of the same name between your
local system and the remote server.

 The only option I have come up with is to keep a copy of the gz file
 in the temporary directory and run wget from there.

You will need to keep the original gz file with a timestamp matching the
server in order for wget to know that the file you have is the same as the
one on the server.

 Unfortunately, at least as far as I can tell, wget does not issue an
 exit code if it has downloaded a newer file.

Better exit codes is on the wish list.

 It would really be nice though if wget simply issued an exit code if
 an updated file were downloaded.

Yes, it would.

 Therefore, I am unable to craft a script that will unpack the file,
 test and install it if a newer version has been downloaded.

Keep one directory that matches the server and another one (or perhaps two)
where you process new files. Before and after wget runs, you can check the
dates on the directory that matches the server. You only need to process
files that changed.

Hope that helps.

 If you mean that you want Wget to find any file that matches that

Seems to me that is a big unless because we've all seen lots of websites
that have http directory listings. Apache will do it out of the box (and by
default) if there is no index.htm[l] file in the directory.

Perhaps we could have a feature to grab all or some of the files in a HTTP
directory listing. Maybe something like this could be made to work:

wget http://www.exelana.com/images/mc*.gif

Perhaps we would need an option such as --http-directory (the first thing
that came to mind, but not necessarily the most intuitive name for the
option) to explicitly tell wget how it is expected to behave. Or perhaps it
can just try stripping the filename when doing an http request and wildcards
are specified.

At any rate (with or without the command line option), wget would retrieve
http://www.exelana.com/images/ and then retrieve any links where the target
matches mc*.gif.

If wget is going to explicitly support http directory listings, it probably
needs to be intelligent enough to ignore the sorting options. In the case of
Apache, that would be things like A HREF=?N=DName/A.

Anyone have any idea how many different http directory listing formats are
out there?

To find out what a command line option does:

  Look in src/main.c in the option_data array for the string to corresponds
to

  the command line option; the entries are of the form:

  { option, 'O', TYPE, data, argtype },

 

  where you're searching for option.

 

  If TYPE is OPT_BOOLEAN or OPT_VALUE:

Note the value of data. Then look at init.c at the commands array for

an entry that starts with the same data. These lines are of the form:

{ data, opt.variable, cmd_TYPE },

 

The corresponding line will tell you what variable gets set when that
option

is selected. Now use grep or some other search tool to find out where
the

variable is referenced.

 

For example, the --accept option sets the value of opt.accepts, which is

referenced in ftp.c and utils.c

 

  If the TYPE is anything else:

Look to see how main.c handles that TYPE.

 

For example, OPT__APPEND_OUTPUT sets the option named logfile and then

sets the variable append_to_log to true. Searching for append_to_log

shows that it is only used in main.c. Checking init.c (as described
above)

for the option logfile shows that it sets the value of opt.lfilename,

which is referenced in mswindows.c, progress.c, and utils.c.

 




 

To add a new command line option:

  The simplest approach is to find an existing option that is close to what
you

  want to accomplish and mirror it. You will need to edit the following
files

  as described.

 

  src/main.c

Add a line to the option_data array in the following format:

  { option, 'O', TYPE, data, argtype },

 

where:

  option   is the long name to be accepted from the command line

  Ois the short name (one character) to be accepted from the

   command or '' if there is no short name; the short name

   must only be assigned to one option. Also, there are very

   few short names available and the maintainers are not

   inclined to give them out unless the option is likely to

   be used frequently.

  TYPE is one of the following standard options:

 OPT_VALUEon the command line, option must be

  followed by a value that will be stored

  ?somewhere?

 OPT_BOOLEAN  option is a boolean value that may appear

  on the command line as --option for true

  or --no-option for false

 OPT_FUNCALL  an internal function will be invoked if the

  option is selected on the command line

   Note: If one of these choices won't work for your option

   you can add a new value of the OPT__XXX to the enum list

   and add special code to handle it in src/main.c.

  data For OPT_VALUE and OPT_BOOLEAN, the name assigned to the

   option in the commands array defined in src/init.c (see

   below). For OPT_FUNCALL, a pointer to the function to be

   invoked.

  argtype  For OPT_VALUE and OPT_BOOLEAN, use -1. For OPT_FUNCALL use

   no_argument.

 

NOTE: The options *must* appear in alphabetical order because a Boolean

search is used for the list.

 

  src/main.c

Add the help string to function print_help as follows:

N_(\

  -O,  --optiondoes something nifty.\n),

 

If the short name is '', put spaces in place of -O,.

 

Select a reasonable place to add the text into the help output in one

of the existing groups of options: Startup, Logging and input file,

Download, Directories, HTTP options, HTTPS (SSL/TLS) options,

FTP options, Recursive download, or Recursive accept/reject.

 

  src/options.h

Define the variable to receive the value of the option in the options

structure.

 

  src/init.c

Add a line to the commands array in the following format:

  { data, opt.variable, cmd_TYPE },

 

where:

  data  matches the data string you entered above in the

All that being said, it wouldn't hurt to have a section in the documentation on

However, the big difference would be where the output was directed. When

all interesting (but sanitized) information would be written to the file 
bug_report whether or not the command included --debug, which would also direct

Subject: Suppressing DNS lookups when using wget, forcing specific IP
address

I'm moving a site from one server to another, and want to use wget
-m combined w/ diff -auwr to help make sure the site looks the same
on both servers.

My problem: wget -m sitename.com always downloads the site at its
*current* IP address. Can I tell wget: download sitename.com, but
pretend the IP address of sitename.com is ip.address.of.new.server
instead of ip.address.of.old.server. In other words, suppress the DNS
lookup for sitename.com and force it to use a given IP address.

I've considered kludges like using old.sitename.com vs
new.sitename.com, editing /etc/hosts, using a proxy server, etc,
but I'm wondering if there's a clean solution here?

On the command line you can use --post-data=”a=1b=2” or you can put the

you would use --post-file=foo.

Subject: Suggesting Feature: Download anything newer than...

I'm a very frequent user of wget, but must admit I haven't
dived too deep into various options - but as far as I can
tell, what I'm about to suggest is not a current feature.
If it is, can somebody tell me how to access it?  0:-)

What I'm suggesting is something similar to -N (check
timestamp and download newer) and may perhaps be used more
as a modifier to -N than a seperate option.

I occationally make a mirror of certain site with wget, and
then throw it into an archive.  Unfortuanately, a few months
(year) later when I want to catch-up with any updates, I either
have to mirror the whole thing again or locate the old archive
and unpack it (and I haven't necesserely preserved the whole
directory structure).

What I would love was the ability to specify (through an option)
an arbitrary timestamp (a date... and perhaps time), and for
only files created/modified after this time to be downloaded (e.g.
the approximate time for the creation of my latest archive).

I am envision it as based on the -N option; except that rather
than looking on the time-stamp - or the size or even the
existance - of a local file, it would only compare the remote file's
timestamp to the supplied timestamp - and download if the remote
file was newer.  Of course, it would probably be h*** of a lot worse
to program than just rewriting the -N option.  :-)

It would have to parse links in HTML-files (HTML) or traverse
directories (FTP).

Usually it would be used when no local mirror existed, and then
creating a mirror of just files made after a certain time (it would
of course have to create a dir-structure containing directories
also older than the specified time, but no older files).  However
being able to use it (a specified time) together with the -N or
--mirror option, may also be useful when updating a local mirror
(though I can't actually see when); so perhaps it should be an option
to be used in *companion* with -N (rather than instead of -N)... or
at least let it be *possible* to use it together with -N and --mirror
as well as by itself.

NXDOMAIN is short hand for non-existent domain. It means the domain name

having a non-published telephone number; if you know my number, you can call
me, but it won't do you any good to call directory assistance because they
can't tell you my number.)

If your web browser is able to find the site then it should be possible for
wget to find it too. But, since it's not a straightforward DNS lookup,
you'll have to figure out how your browser is pulling off the magic.

One way to do that is to run with a local proxy (such as Achilles) and study
what happens between your browser and the server. If you compare that with
the debug output of wget, you'll have an idea of where the flow is different
and what wget might do to make it work.

I'm sure someone can point out open-source options for the proxy. :-)

Have fun exploring.

Hi,

I'm trying to use wget to download 100s of JPGs into a cache server with a
different directory/filename heirarchy. What I tried to do was to create a
text or html file with 1 line for each download (e.g. URL -nd -P [new-path]
-O [new-filename]) and use the --input-file= switch, However, I discovered
that I cannot rename the path/filename of the file inside the input file.

Also, the JPGs will not all come from the same domain but they need to be
placed in a flattened directory tree with different filenames.

Can anyone offer me advice on how to best accomplish this? I'm using the
windows platform.

SI units are for decimal-based numbers (that is powers of 10) whereas
computer programs typically use binary-based numbers (powers of 2). It's
convenient for humans to equate 10^3 (1,000) with 2^10 (1,024) but with
large numbers, these values quickly diverge: 999k or 999 * 10^3 = 999,000,
but 999K or 999 * 2^10 = 1,022,976.

For what it's worth, according to Wikipedia either k or K is acceptable for

All of this is described in the Wikipedia article I referenced.

It's true that International Electrotechnical Commission prefers the term

used in computer standards.

Searching ietf.org there are 1,880 matches for kilobytes and only 2 for
kibibytes and those are both feedback from one individual arguing for the
use of kibibytes instead of kilobytes.

Searching gnu.org there are 452 matches for kilobytes and only 5 for
kibibytes and even then, the following appears:  `KiB' kibibyte: 2^10 =
1024. `K' is special: the SI prefix is `k' and the IEC 60027-2 prefix is
`Ki', but tradition and POSIX use `k' to mean `KiB'.

It seems odd to me that one would suggest that wget is the place to start
changing the long-established trend of using 'k' for 1,024.



RE: wget question (connect multiple times)

A) This is the list for reporting bugs. Questions should go to
wget@sunsite.dk

B) wget does not support multiple time simultaneously

C) The decreased per-file download time you're seeing is (probably) because
wget is reusing its connection to the server to download the second file. It
takes some time to set up a connection to the server regardless of whether
you're downloading one byte or one gigabyte of data. For small files, the
set up time can be a significant part of the overall download time.

Hope that helps!

You should not assume that the file saved by any browser is the same as the
file delivered to the browser by the server. The browser is probably
manipulating line endings to match the conventions on your operating system
when it saves files so that CR, CR-LF, or LF, all become CR-LF (or whatever
your OS uses for line endings).

Hello,
I tried everything, but images, built in via CSS are neither downloaded nor
related with wget.
Example (inline style):
CSS-Terms like

div style=background-image : 
url(/files/inc/image/pjpeg/hintergrund_startseite.jpg); id=pfad 

do not have any effect on the downloaded web-page.

The same thing happens, when you write

{background-image : url(/files/inc/image/pjpeg/hintergrund_startseite.jpg);}

into a css-file.

Maybe other references in CSS do not work either. Perhaps you can prove
this.

If you could fix this problem, wget would be the best tool for me.
Thank you and best regards

RE: regex support RFC

2006-03-31 Thread Tony Lewis
Mauro Tortonesi wrote: 

 no. i was talking about regexps. they are more expressive
 and powerful than simple globs. i don't see what's the
 point in supporting both.

The problem is that users who are expecting globs will try things like
--filter=-file:*.pdf rather than --filter:-file:.*\.pdf. In many cases their
expressions will simply work, which will result in significant confusion
when some expression doesn't work, such as
--filter:-domain:www-*.yoyodyne.com. :-)

It is pretty easy to programmatically convert a glob into a regular
expression. One possibility is to make glob the default input and allow
regular expressions. For example, the following could be equivalent:

--filter:-domain:www-*.yoyodyne.com
--filter:-domain,r:www-.*\.yoyodyne\.com

Internally, wget would convert the first into the second and then treat it
as a regular expression. For the vast majority of cases, glob will work just
fine.

One might argue that it's a lot of work to implement regular expressions if
the default input format is a glob, but I think we should aim for both lack
of confusion and robust functionality. Using ,r means people get regular
expressions when they want them and know what they're doing. The universe of
wget users who know what they're doing are mostly subscribed to this
mailing list; the rest of them send us mail saying please CC me as I'm not
on the list. :-)

If we go this route, I'm wondering if the appropriate conversion from glob
to regular expression should take directory separators into account, such
as:

--filter:-path:path/to/*

becoming the same as:

--filter:-path,r:path/to/[^/]*

or even:

--filter:-path,r:path[/\\]to[/\\][^/\\]*

Should the glob match path/to/sub/dir? (I suspect it shouldn't.)

I didn't miss the point at all. I'm trying to make a completely different

tell them that the argument to --filter is a regular expression). This
mailing list will get a huge number of bug reports when users try to use
globs that fail.

Yes, regular expressions are used elsewhere on Unix, but not everywhere. The
shell is the most obvious comparison for user input dealing with expressions
that select multiple objects; the shell uses globs.

Personally, I will be quite happy if --filter only supports regular
expressions because I've been using them quite effectively for years. I just
don't think the same thing can be said for the typical wget user. We've
already had disagreements in this chain about what would match a particular
regular expression; I suspect everyone involved in the conversation could
have correctly predicted what the equivalent glob would do.

I don't think ,r complicates the command that much. Internally, the only
additional work for supporting both globs and regular expressions is a
function that converts a glob into a regexp when ,r is not requested.
That's a straightforward transformation.

RE: wget 1.10.x fixed recursive ftp download over proxy

2006-01-10 Thread Tony Lewis
Here's what your version of the code said:

if ((opt.recursive || opt.page_requisites)
 ((url_scheme (*t) != SCHEME_FTP) || 
(opt.use_proxy  url_scheme (*t) == SCHEME_FTP)))

which means (for the bit after the ):

FTP  ^FTP
proxyT T
^proxy   F T

Regardless of whether it is FTP, the condition will always succeed if
use_proxy is true. Therefore, a simpler way of writing the expression is:
(url_scheme (*t) != SCHEME_FTP) || opt.use_proxy

You're right that I shouldn't have moved opt.use_proxy with the other
command line options. My revised suggestion is:

if ((opt.recursive || opt.page_requisites)
 ((url_scheme (*t) != SCHEME_FTP) || opt.use_proxy))
  status = retrieve_tree (*t);
else
  status = retrieve_url
  (*t, filename, redirected_URL, NULL, dt);

[EMAIL PROTECTED]Subject: wget 1.10.x fixed recursive ftp download 
over proxy
Hi,
We once encounter an annoying problem of recursively downloading FTP data 
using wget, through a ftp-over-http proxy. Previously it was the proxy firmware 
that does not support recursive downloads, but even upgrading we realized there 
is problem with wget itself as well.
We found that with new proxy firmwire, the older wget 1.7.x can download FTP 
database recursively, but the newer version (1.9.x and 1.10.x) can not. That 
means there must be something wrong with the code.
I also confirmed this is a known bug for wget since 2003 and it is strange it 
has not been fixed for a long time.
To fix this problem, I took some time to analyze its code and it happens wget 
uses different method to get the list of files for a destination folder when 
trying to do recursive download. For normal FTP, it uses FTP command "LIST" to 
get the file listing. For normal HTTP, it uses its internal method 
"retrieve_tree()" to generate the lists. 
In main.c, it does to use retrieve_tree() function to generate list if the 
traffic is FTP. Howerver, when we use ftp-over-http proxy, the actual request to 
the server is HTTP request, where the "LIST" FTP command wont work, so we only 
get one "index.html" file.
if ((opt.recursive || opt.page_requisites)  
url_scheme (*t) != SCHEME_FTP) status = retrieve_tree 
(*t);else status = retrieve_url  (*t, filename, 
redirected_URL, NULL, dt);
In this scenario, we need to modify the code to force wget call retrieve_tree 
function for FTP traffic if the proxy is involved 
if ((opt.recursive || opt.page_requisites)//  url_scheme (*t) != 
SCHEME_FTP) ((url_scheme (*t) != 
SCHEME_FTP) ||  (opt.use_proxy 
 url_scheme (*t) == SCHEME_FTP))) status = 
retrieve_tree (*t);else status = retrieve_url  (*t, 
filename, redirected_URL, NULL, dt);
After patching the main.c, the new wget works perfectly for FTP recursive 
downloading, both with proxy and without proxy. This patching works for 1.9.x 
and 1.10.x till the latest version so far (1.10.2).-- CHEN Peng [EMAIL PROTECTED]

wget is not terminating the path at the command line delimiter, Windows is.
In the same way that you have to enter:

wget --directory-prefix=c:/my prefix
or the command processor will split the directory path at the space before

When trying to recreate a form in wget, you have to send the data the server

In your browser, view the source to http://safari.informit.com/?FPI=uicode=

formatting information for the table that contains the form and reformatted
what was left to make it readable.

Note that the server expects the data to be posted to JVXSL.asp and that
there are a bunch of fields that must be supplied in order for the server to
process the login request. In addition, the two fields you supply are called
usr and pwd. So your first wget command line will look something like

When you specify a directory, it is up to the web server to determine what

some will return some file (such as index.html), and others will return an

For example, Apache might return (in this order): index.html, index.htm, a
directory listing (or a 403 Forbidden response if the configuration
disallows directory listings). The actual list of files that Apache will
search for and the order in which they are selected is determined by the
configuration.

If the web server returns any information, wget has to save the information
that is returned in *some* local file. It chooses to name that local file
index.html since it has no way of knowing where the information might have
actually been stored on the server.

There are no options on the command line for what you're attempting to do.

Neither wget nor the server you're contacting understand *.pdf in a URI.
In the case of wget, it is designed to read web pages (HTML files) and then
collect a list of resources that are referenced in those pages, which it
then retrieves. In the case of the web server, it is designed to return
individual objects on request (X.pdf or Y.pdf, but not *.pdf). Some web
servers will return a list of files if you specify a directory, but you
already tried that in your first use case.

Try coming at this from a different direction. If you were going to manually
download every PDF from that directory, how would YOU figure out the names
of each one? Is there a web page that contains a list somewhere? If so,
point wget there.

Hope that helps.

 Any thoughts of adding support for Stratus VOS file structures?

Your question is a little too vague -- even for me (I used to work for
Stratus and actually know what VOS is :-)

What file structures are you needing supported that wget does not currently
support? Are you needing support when wget is running on Stratus and saving
files that it downloads from somewhere else? Or are you needing support for
VOS file structures when wget is retrieving a file from a VOS system? If the
latter, does this support only apply if both systems are VOS?

Re: Escaping semicolons

Phil Endecott wrote:

 There is not much to go on in terms of specifications.  The closest is
 RFC1738, which includes BNF for a file: URI.  However it is ten years
 old, so whether it reflects current practice I do not know.  But it does

 I conclude from this that wget should be replacing ; with its %3b escape
 sequence.

I think you're confusing what wget is required to do with URLs entered on
the command line and what it chooses to do with the resulting files that it
saves. If a unencoded name of retrieved resource cannot be stored on the
local file system, wget encodes it to create a valid name.

  There is no need to escape ampersands either.

 Tony, are you suggesting that this is legal HTML?

   a href=http://foo.foo/foo.cgi?p1=v1p2=v2;Foo/a

 I'm fairly confident that you need to escape the  to make it valid, i.e.

   a href=http://foo.foo/foo.cgi?p1=v1amp;p2=v2;Foo/a

Just out of curiosity, did you try to implement your theory and see what
happens? If you did, you would that the first version works and the second
does not.

By the way, the correct URI encoding of ampersand is %26, not amp;. The
latter encoding is used for ampersands in HTML markup.

With regard to whether ampersand needs to be encoded, you're misreading the
RFC:

   Many URL schemes reserve certain characters for a special meaning:
   their appearance in the scheme-specific part of the URL has a
   designated semantics. If the character corresponding to an octet is
   reserved in a scheme, the octet must be encoded.  The characters ;,
   /, ?, :, @, = and  are the characters which may be
   reserved for special meaning within a scheme. No other characters may
   be reserved within a scheme.

   Usually a URL has the same interpretation when an octet is
   represented by a character and when it encoded. However, this is not
   true for reserved characters: encoding a character reserved for a
   particular scheme may change the semantics of a URL.

The RFC says that you have to escape Reserved characters if that character
appears in the name of the resource you're trying to retrieve. That is, if
you're trying to retrieve a file named ab.txt, you refer to that file as
a%26b.txt in the URL because you're using the ampersand for a non-reserved
purpose.

If you're using a reserved character for the purpose that it has been
reserved (in this case, separating parameters), you do NOT want to encode
it. The URL you proposed (after correcting the encoding of the ampersand) is
requesting a resource (probably a file) whose name is foo.cgi?p1=v1p2=v2.
It is NOT requesting that the script foo.cgi be executed with argument p1
having a value of v1 and p2 having a value of v2.

Hope that helps.
