* Overview:: Features of Wget.
@cindex overview
@cindex features
+@c man begin DESCRIPTION
GNU Wget is a freely available network utility to retrieve files from
the World Wide Web, using @sc{http} (Hyper Text Transfer Protocol) and
@sc{ftp} (File Transfer Protocol), the two most widely used Internet
and disconnect from the system, letting Wget finish the work. By
contrast, most of the Web browsers require constant user's presence,
which can be a great hindrance when transferring a lot of data.
+@c man end
@sp 1
+@c man begin DESCRIPTION
@item
Wget is capable of descending recursively through the structure of
@sc{html} documents and @sc{ftp} directory trees, making a local copy of
feature can be used to mirror archives and home pages, or traverse the
web in search of data, like a @sc{www} robot (@pxref{Robots}). In that
spirit, Wget understands the @code{norobots} convention.
+@c man end
@sp 1
+@c man begin DESCRIPTION
@item
File name wildcard matching and recursive mirroring of directories are
available when retrieving via @sc{ftp}. Wget can read the time-stamp
retrieval, and automatically retrieve the new version if it has. This
makes Wget suitable for mirroring of @sc{ftp} sites, as well as home
pages.
+@c man end
@sp 1
+@c man begin DESCRIPTION
@item
Wget works exceedingly well on slow or unstable connections,
retrying the document until it is fully retrieved, or until a
user-specified retry count is surpassed. It will try to resume the
download from the point of interruption, using @code{REST} with @sc{ftp}
and @code{Range} with @sc{http} servers that support them.
+@c man end
@sp 1
+@c man begin DESCRIPTION
@item
By default, Wget supports proxy servers, which can lighten the network
load, speed up retrieval and provide access behind firewalls. However,
gateway, you can get the socks library and build Wget with support for
socks. Wget also supports the passive @sc{ftp} downloading as an
option.
+@c man end
@sp 1
+@c man begin DESCRIPTION
@item
Builtin features offer mechanisms to tune which links you wish to follow
(@pxref{Following Links}).
+@c man end
@sp 1
+@c man begin DESCRIPTION
@item
The retrieval is conveniently traced with printing dots, each dot
representing a fixed amount of data received (1KB by default). These
representations can be customized to your preferences.
+@c man end
@sp 1
+@c man begin DESCRIPTION
@item
Most of the features are fully configurable, either through command line
options, or via the initialization file @file{.wgetrc} (@pxref{Startup
File}). Wget allows you to define @dfn{global} startup files
(@file{/usr/local/etc/wgetrc} by default) for site settings.

@node Invoking, Recursive Retrieval, Overview, Top
@chapter Invoking
By default, Wget is very simple to invoke. The basic syntax is:
@example
+@c man begin SYNOPSIS
wget [@var{option}]@dots{} [@var{URL}]@dots{}
+@c man end
@end example
Wget will simply download all the @sc{url}s specified on the command
wget -X '' -X /~nobody,/~somebody
@end example
+@c man begin OPTIONS

and parsed as if they had been retrieved from the Web.
@cindex continue retrieval
+@cindex incomplete downloads
+@cindex resume download
@item -c
@itemx --continue
-Continue getting an existing file. This is useful when you want to
-finish up the download started by another program, or a previous
-instance of Wget. Thus you can write:
+Continue getting a partially-downloaded file. This is useful when you
+want to finish up a download started by a previous instance of Wget, or
+by another program. For instance:
@example
wget -c ftp://sunsite.doc.ic.ac.uk/ls-lR.Z
@end example
-If there is a file name @file{ls-lR.Z} in the current directory, Wget
+If there is a file named @file{ls-lR.Z} in the current directory, Wget
will assume that it is the first portion of the remote file, and will
-require the server to continue the retrieval from an offset equal to the
+ask the server to continue the retrieval from an offset equal to the
length of the local file.
-Note that you need not specify this option if all you want is Wget to
-continue retrieving where it left off when the connection is lost---Wget
-does this by default. You need this option only when you want to
-continue retrieval of a file already halfway retrieved, saved by another
-@sc{ftp} client, or left by Wget being killed.
-
-Without @samp{-c}, the previous example would just begin to download the
-remote file to @file{ls-lR.Z.1}. The @samp{-c} option is also
-applicable for @sc{http} servers that support the @code{Range} header.
-
-Note that if you use @samp{-c} on a file that's already downloaded
-completely, @samp{@var{file}} will not be changed, nor will a second
-@samp{@var{file}.1} copy be created.
-
+Note that you don't need to specify this option if you just want the
+current invocation of Wget to retry downloading a file should the
+connection be lost midway through. This is the default behavior.
+@samp{-c} only affects resumption of downloads started @emph{prior} to
+this invocation of Wget, and whose local files are still sitting around.
+
+Without @samp{-c}, the previous example would just download the remote
+file to @file{ls-lR.Z.1}, leaving the truncated @file{ls-lR.Z} file
+alone.
+
+Beginning with Wget 1.7, if you use @samp{-c} on a non-empty file, and
+it turns out that the server does not support continued downloading,
+Wget will refuse to start the download from scratch, which would
+effectively ruin existing contents. If you really want the download to
+start from scratch, remove the file.
+
+Also beginning with Wget 1.7, if you use @samp{-c} on a file which is of
+equal size as the one on the server, Wget will refuse to download the
+file and print an explanatory message. The same happens when the file
+is smaller on the server than locally (presumably because it was changed
+on the server since your last download attempt)---because ``continuing''
+is not meaningful, no download occurs.
+
+On the other side of the coin, while using @samp{-c}, any file that's
+bigger on the server than locally will be considered an incomplete
+download and only @code{(length(remote) - length(local))} bytes will be
+downloaded and tacked onto the end of the local file. This behavior can
+be desirable in certain cases---for instance, you can use @samp{wget -c}
+to download just the new portion that's been appended to a data
+collection or log file.
+
+However, if the file is bigger on the server because it's been
+@emph{changed}, as opposed to just @emph{appended} to, you'll end up
+with a garbled file. Wget has no way of verifying that the local file
+is really a valid prefix of the remote file. You need to be especially
+careful of this when using @samp{-c} in conjunction with @samp{-r},
+since every file will be considered as an "incomplete download" candidate.
+
+Another instance where you'll get a garbled file if you try to use
+@samp{-c} is if you have a lame @sc{http} proxy that inserts a
+``transfer interrupted'' string into the local file. In the future a
+``rollback'' option may be added to deal with this case.
+
+Note that @samp{-c} only works with @sc{ftp} servers and with @sc{http}
+servers that support the @code{Range} header.
+
+@cindex progress indicator
@cindex dot style
-@cindex retrieval tracing style
-@item --dot-style=@var{style}
-Set the retrieval style to @var{style}. Wget traces the retrieval of
-each document by printing dots on the screen, each dot representing a
-fixed amount of retrieved data. Any number of dots may be separated in
-a @dfn{cluster}, to make counting easier. This option allows you to
-choose one of the pre-defined styles, determining the number of bytes
-represented by a dot, the number of dots in a cluster, and the number of
-dots on the line.
-
-With the @code{default} style each dot represents 1K, there are ten dots
-in a cluster and 50 dots in a line. The @code{binary} style has a more
-``computer''-like orientation---8K dots, 16-dots clusters and 48 dots
-per line (which makes for 384K lines). The @code{mega} style is
-suitable for downloading very large files---each dot represents 64K
-retrieved, there are eight dots in a cluster, and 48 dots on each line
-(so each line contains 3M). The @code{micro} style is exactly the
-reverse; it is suitable for downloading small files, with 128-byte dots,
-8 dots per cluster, and 48 dots (6K) per line.
+@item --progress=@var{type}
+Select the type of the progress indicator you wish to use. Legal
+indicators are ``dot'' and ``bar''.
+
+The ``dot'' indicator is used by default. It traces the retrieval by
+printing dots on the screen, each dot representing a fixed amount of
+downloaded data.
+
+When using the dotted retrieval, you may also set the @dfn{style} by
+specifying the type as @samp{dot:@var{style}}. Different styles assign
+different meaning to one dot. With the @code{default} style each dot
+represents 1K, there are ten dots in a cluster and 50 dots in a line.
+The @code{binary} style has a more ``computer''-like orientation---8K
+dots, 16-dots clusters and 48 dots per line (which makes for 384K
+lines). The @code{mega} style is suitable for downloading very large
+files---each dot represents 64K retrieved, there are eight dots in a
+cluster, and 48 dots on each line (so each line contains 3M).
+
+Specifying @samp{--progress=bar} will draw a nice ASCII progress bar
+graphics (a.k.a ``thermometer'' display) to indicate retrieval. If the
+output is not a TTY, this option will be ignored, and Wget will revert
+to the dot indicator. If you want to force the bar indicator, use
+@samp{--progress=bar:force}.
@item -N
@itemx --timestamping
Note that this option is turned on by default in the global
@file{wgetrc} file.
+@cindex wait, random
+@cindex random wait
+@itemx --random-wait
+Some web sites may perform log analysis to identify retrieval programs
+such as Wget by looking for statistically significant similarities in
+the time between requests. This option causes the time between requests
+to vary between 0 and 2 * @var{wait} seconds, where @var{wait} was
+specified using the @samp{-w} or @samp{--wait} options, in order to mask
+Wget's presence from such analysis.
+
+A recent article in a publication devoted to development on a popular
+consumer platform provided code to perform this analysis on the fly.
+Its author suggested blocking at the class C address level to ensure
+automated retrieval programs were blocked despite changing DHCP-supplied
+addresses.
+
+The @samp{--random-wait} option was inspired by this ill-advised
+recommendation to block many unrelated users from a web site due to the
+actions of one.
+
@cindex proxy
@item -Y on/off
@itemx --proxy=on/off
Caching is allowed by default.
+@cindex cookies
+@item --cookies=on/off
+When set to off, disable the use of cookies. Cookies are a mechanism
+for maintaining server-side state. The server sends the client a cookie
+using the @code{Set-Cookie} header, and the client responds with the
+same cookie upon further requests. Since cookies allow the server
+owners to keep track of visitors and for sites to exchange this
+information, some consider them a breach of privacy. The default is to
+use cookies; however, @emph{storing} cookies is not on by default.
+
+@cindex loading cookies
+@cindex cookies, loading
+@item --load-cookies @var{file}
+Load cookies from @var{file} before the first HTTP retrieval. The
+format of @var{file} is one used by Netscape and Mozilla, at least their
+Unix version.
+
+@cindex saving cookies
+@cindex cookies, saving
+@item --save-cookies @var{file}
+Save cookies from @var{file} at the end of session. Cookies whose
+expiry time is not specified, or those that have already expired, are
+not saved.
+
@cindex Content-Length, ignore
@cindex ignore length
@item --ignore-length
@section FTP Options
@table @samp
-@cindex symbolic links, retrieving
-@item --retr-symlinks
-Usually, when retrieving @sc{ftp} directories recursively and a symbolic
-link is encountered, the linked-to file is not downloaded. Instead, a
-matching symbolic link is created on the local filesystem. The
-pointed-to file will not be downloaded unless this recursive retrieval
-would have encountered it separately and downloaded it anyway.
-
-When @samp{--retr-symlinks} is specified, however, symbolic links are
-traversed and the pointed-to files are retrieved. At this time, this
-option does not cause Wget to traverse symlinks to directories and
-recurse through them, but in the future it should be enhanced to do
-this.
-
-Note that when retrieving a file (not a directory) because it was
-specified on the commandline, rather than because it was recursed to,
-this option has no effect. Symbolic links are always traversed in this
-case.
+@cindex .listing files, removing
+@item -nr
+@itemx --dont-remove-listing
+Don't remove the temporary @file{.listing} files generated by @sc{ftp}
+retrievals. Normally, these files contain the raw directory listings
+received from @sc{ftp} servers. Not removing them can be useful for
+debugging purposes, or when you want to be able to easily check on the
+contents of remote server directories (e.g. to verify that a mirror
+you're running is complete).
+
+Note that even though Wget writes to a known filename for this file,
+this is not a security hole in the scenario of a user making
+@file{.listing} a symbolic link to @file{/etc/passwd} or something and
+asking @code{root} to run Wget in his or her directory. Depending on
+the options used, either Wget will refuse to write to @file{.listing},
+making the globbing/recursion/time-stamping operation fail, or the
+symbolic link will be deleted and replaced with the actual
+@file{.listing} file, or the listing will be written to a
+@file{.listing.@var{number}} file.
+
+Even though this situation isn't a problem, though, @code{root} should
+never run Wget in a non-trusted user's directory. A user could do
+something as simple as linking @file{index.html} to @file{/etc/passwd}
+and asking @code{root} to run Wget with @samp{-N} or @samp{-r} so the file
+will be overwritten.
@cindex globbing, toggle
@item -g on/off
Use the @dfn{passive} @sc{ftp} retrieval scheme, in which the client
initiates the data connection. This is sometimes required for @sc{ftp}
to work behind firewalls.
+
+@cindex symbolic links, retrieving
+@item --retr-symlinks
+Usually, when retrieving @sc{ftp} directories recursively and a symbolic
+link is encountered, the linked-to file is not downloaded. Instead, a
+matching symbolic link is created on the local filesystem. The
+pointed-to file will not be downloaded unless this recursive retrieval
+would have encountered it separately and downloaded it anyway.
+
+When @samp{--retr-symlinks} is specified, however, symbolic links are

@cindex link conversion
@item -k
@itemx --convert-links
-Convert the non-relative links to relative ones locally. Only the
-references to the documents actually downloaded will be converted; the
-rest will be left unchanged.
+After the download is complete, convert the links in the document to
+make them suitable for local viewing. This affects not only the visible
+hyperlinks, but any part of the document that links to external content,
+such as embedded images, links to style sheets, hyperlinks to non-HTML
+content, etc.
+
+Each link will be changed in one of the two ways:
+
+@itemize @bullet
+@item
+The links to files that have been downloaded by Wget will be changed to
+refer to the file they point to as a relative link.
+
+Example: if the downloaded file @file{/foo/doc.html} links to
+@file{/bar/img.gif}, also downloaded, then the link in @file{doc.html}
+will be modified to point to @samp{../bar/img.gif}. This kind of
+transformation works reliably for arbitrary combinations of directories.
+
+@item
+The links to files that have not been downloaded by Wget will be changed
+to include host name and absolute path of the location they point to.
+
+Example: if the downloaded file @file{/foo/doc.html} links to
+@file{/bar/img.gif} (or to @file{../bar/img.gif}), then the link in
+@file{doc.html} will be modified to point to
+@file{http://@var{hostname}/bar/img.gif}.
+@end itemize
+
+Because of this, local browsing works reliably: if a linked file was
+downloaded, the link will refer to its local name; if it was not
+downloaded, the link will refer to its full Internet address rather than
+presenting a broken link. The fact that the former links are converted
+to relative links ensures that you can move the downloaded hierarchy to
+another directory.
Note that only at the end of the download can Wget know which links have
-been downloaded. Because of that, much of the work done by @samp{-k}
-will be performed at the end of the downloads.

-@item -nr
-@itemx --dont-remove-listing
-Don't remove the temporary @file{.listing} files generated by @sc{ftp}

-access the full remote file list when running a mirror, or for debugging
-purposes.

@cindex page requisites
@cindex required images, downloading
@item -p
For instance, say document @file{1.html} contains an @code{<IMG>} tag
referencing @file{1.gif} and an @code{<A>} tag pointing to external
-document @file{2.html}. Say that @file{2.html} is the same but that its
+document @file{2.html}. Say that @file{2.html} is similar but that its
image is @file{2.gif} and it links to @file{3.html}. Say this
continues up to some arbitrarily high number.
this is not the case, because @samp{-l 0} is equivalent to
@samp{-l inf}---that is, infinite recursion. To download a single HTML
page (or a handful of them, all specified on the commandline or in a
-@samp{-i} @sc{url} input file) and its requisites, simply leave off
-@samp{-p} and @samp{-l}:
+@samp{-i} @sc{url} input file) and its (or their) requisites, simply leave off
+@samp{-r} and @samp{-l}:
@example
wget -p http://@var{site}/1.html
wget -E -H -k -K -nh -p http://@var{site}/@var{document}
@end example
+In one case you'll need to add a couple more options. If @var{document}
+is a @code{<FRAMESET>} page, the "one more hop" that @samp{-p} gives you
+won't be enough---you'll get the @code{<FRAME>} pages that are
+referenced, but you won't get @emph{their} requisites. Therefore, in
+this case you'll need to add @samp{-r -l1} to the commandline. The
+@samp{-r -l1} will recurse from the @code{<FRAMESET>} page to to the
+@code{<FRAME>} pages, and the @samp{-p} will get their requisites. If
+you're already using a recursion level of 1 or more, you'll need to up
+it by one. In the future, @samp{-p} may be made smarter so that it'll
+do "two more hops" in the case of a @code{<FRAMESET>} page.
+
To finish off this topic, it's worth knowing that Wget's idea of an
external document link is any URL specified in an @code{<A>} tag, an
@code{<AREA>} tag, or a @code{<LINK>} tag other than @code{<LINK
@xref{Directory-Based Limits}, for more details.

-For each directory files must be retrieved from, Wget will use the

-Wget is @dfn{free software}, where ``free'' refers to liberty, not

-distribute it to other people, and even---if you want---charge money for
-any of these things. The sole restriction is that you have to grant
