* Overview:: Features of Wget.
@item
Wget supports proxy servers, which can lighten the network load, speed
up retrieval and provide access behind firewalls. However, if you are
-behind a firewall that requires that you use a socks style 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.
+behind a firewall that requires that you use a socks style gateway,
+you can get the socks library and build Wget with support for socks.
+Wget uses the passive @sc{ftp} downloading by default, active @sc{ftp}
+being an option.
+
+@sp 1
+@item
+Wget supports IP version 6, the next generation of IP. IPv6 is
+autodetected at compile-time, and can be disabled at either build or
+run time. Binaries built with IPv6 support work well in both
+IPv4-only and dual family environments.

@node Option Syntax
@section Option Syntax
@cindex option syntax
@cindex syntax of options
-Since Wget uses GNU getopts to process its arguments, every option has a
-short form and a long form. Long options are more convenient to
-remember, but take time to type. You may freely mix different option
-styles, or specify options after the command-line arguments. Thus you
-may write:
+Since Wget uses GNU getopt to process command-line arguments, every
+option has a long form along with the short one. Long options are
+more convenient to remember, but take time to type. You may freely
+mix different option styles, or specify options after the command-line
+arguments. Thus you may write:
@example
wget -r --tries=10 http://fly.srk.fer.hr/ -o log
wget -X '' -X /~nobody,/~somebody
@end example
-@c man begin OPTIONS
+Most options that do not accept arguments are @dfn{boolean} options,
+so named because their state can be captured with a yes-or-no
+(``boolean'') variable. For example, @samp{--follow-ftp} tells Wget
+to follow FTP links from HTML files and, on the other hand,
+@samp{--no-glob} tells it not to perform file globbing on FTP URLs. A
+boolean option is either @dfn{affirmative} or @dfn{negative}
+(beginning with @samp{--no}). All such options share several
+properties.
+
+Unless stated otherwise, it is assumed that the default behavior is
+the opposite of what the option accomplishes. For example, the
+documented existence of @samp{--follow-ftp} assumes that the default
+is to @emph{not} follow FTP links from HTML pages.
+
+Affirmative options can be negated by prepending the @samp{--no-} to
+the option name; negative options can be negated by omitting the
+@samp{--no-} prefix. This might seem superfluous---if the default for
+an affirmative option is to not do something, then why provide a way
+to explicitly turn it off? But the startup file may in fact change
+the default. For instance, using @code{follow_ftp = off} in
+@file{.wgetrc} makes Wget @emph{not} follow FTP links by default, and
+using @samp{--no-follow-ftp} is the only way to restore the factory
+default from the command line.
@node Basic Startup Options
@section Basic Startup Options

@cindex downloading multiple times
to specifying @samp{--dns-timeout}, @samp{--connect-timeout}, and
@samp{--read-timeout}, all at the same time.
-Whenever Wget connects to or reads from a remote host, it checks for a
-timeout and aborts the operation if the time expires. This prevents
-anomalous occurrences such as hanging reads or infinite connects. The
-only timeout enabled by default is a 900-second timeout for reading.
-Setting timeout to 0 disables checking for timeouts.
+When interacting with the network, Wget can check for timeout and
+abort the operation if it takes too long. This prevents anomalies
+like hanging reads and infinite connects. The only timeout enabled by
+default is a 900-second read timeout. Setting a timeout to 0 disables
+it altogether. Unless you know what you are doing, it is best not to
+change the default timeout settings.
-Unless you know what you are doing, it is best not to set any of the
-timeout-related options.
+All timeout-related options accept decimal values, as well as
+subsecond values. For example, @samp{0.1} seconds is a legal (though
+unwise) choice of timeout. Subsecond timeouts are useful for checking
+server response times or for testing network latency.
@cindex DNS timeout
@cindex timeout, DNS
@cindex read timeout
@cindex timeout, read
@item --read-timeout=@var{seconds}
-Set the read (and write) timeout to @var{seconds} seconds. Reads that
-take longer will fail. The default value for read timeout is 900
+Set the read (and write) timeout to @var{seconds} seconds. The
+``time'' of this timeout refers @dfn{idle time}: if, at any point in
+the download, no data is received for more than the specified number
+of seconds, reading fails and the download is restarted. This option
+does not directly affect the duration of the entire download.
+
+Of course, the remote server may choose to terminate the connection
+sooner than this option requires. The default read timeout is 900
seconds.
@cindex bandwidth, limit
Limit the download speed to @var{amount} bytes per second. Amount may
be expressed in bytes, kilobytes with the @samp{k} suffix, or megabytes
with the @samp{m} suffix. For example, @samp{--limit-rate=20k} will
-limit the retrieval rate to 20KB/s. This kind of thing is useful when,
-for whatever reason, you don't want Wget to consume the entire available
-bandwidth.
+limit the retrieval rate to 20KB/s. This is useful when, for whatever
+reason, you don't want Wget to consume the entire available bandwidth.
+
+This option allows the use of decimal numbers, usually in conjunction
+with power suffixes; for example, @samp{--limit-rate=2.5k} is a legal
+value.
Note that Wget implements the limiting by sleeping the appropriate
amount of time after a network read that took less time than specified
actions of one.
@cindex proxy
-@item -Y on/off
-@itemx --proxy=on/off
-Turn proxy support on or off. The proxy is on by default if the
-appropriate environment variable is defined.
+@itemx --no-proxy
+Don't use proxies, even if the appropriate @code{*_proxy} environment
+variable is defined.
For more information about the use of proxies with Wget, @xref{Proxies}.
@cindex DNS cache
@cindex caching of DNS lookups
-@item --dns-cache=off
-Turn off caching of DNS lookups. Normally, Wget remembers the addresses
-it looked up from DNS so it doesn't have to repeatedly contact the DNS
-server for the same (typically small) set of addresses it retrieves
-from. This cache exists in memory only; a new Wget run will contact DNS
-again.
-
-However, in some cases it is not desirable to cache host names, even for
-the duration of a short-running application like Wget. For example,
-some HTTP servers are hosted on machines with dynamically allocated IP
-addresses that change from time to time. Their DNS entries are updated
-along with each change. When Wget's download from such a host gets
-interrupted by IP address change, Wget retries the download, but (due to
-DNS caching) it contacts the old address. With the DNS cache turned
-off, Wget will repeat the DNS lookup for every connect and will thus get
-the correct dynamic address every time---at the cost of additional DNS
-lookups where they're probably not needed.
-
-If you don't understand the above description, you probably won't need
-this option.
+@item --no-dns-cache
+Turn off caching of DNS lookups. Normally, Wget remembers the IP
+addresses it looked up from DNS so it doesn't have to repeatedly
+contact the DNS server for the same (typically small) set of hosts it
+retrieves from. This cache exists in memory only; a new Wget run will
+contact DNS again.
+
+However, it has been reported that in some situations it is not
+desirable to cache host names, even for the duration of a
+short-running application like Wget. With this option Wget issues a
+new DNS lookup (more precisely, a new call to @code{gethostbyname} or
+@code{getaddrinfo}) each time it makes a new connection. Please note
+that this option will @emph{not} affect caching that might be
+performed by the resolving library or by an external caching layer,
+such as NSCD.
+
+If you don't understand exactly what this option does, you probably
+won't need it.
@cindex file names, restrict
@cindex Windows file names
switched off. You can use @samp{--restrict-file-names=nocontrol} to
turn off escaping of control characters without affecting the choice of
the OS to use as file name restriction mode.
+
+@cindex IPv6
+@itemx -4
+@itemx --inet4-only
+@itemx -6
+@itemx --inet6-only
+Force connecting to IPv4 or IPv6 addresses. With @samp{--inet4-only}
+or @samp{-4}, Wget will only connect to IPv4 hosts, ignoring AAAA
+records in DNS, and refusing to connect to IPv6 addresses specified in
+URLs. Conversely, with @samp{--inet6-only} or @samp{-6}, Wget will
+only connect to IPv6 hosts and ignore A records and IPv4 addresses.
+
+Neither options should be needed normally. By default, an IPv6-aware
+Wget will use the address family specified by the host's DNS record.
+If the DNS specifies both an A record and an AAAA record, Wget will
+try them in sequence until it finds one it can connect to.
+
+These options can be used to deliberately force the use of IPv4 or
+IPv6 address families on dual family systems, usually to aid debugging
+or to deal with broken network configuration. Only one of
+@samp{--inet6-only} and @samp{--inet4-only} may be specified in the
+same command. Neither option is available in Wget compiled without
+IPv6 support.
+
+@item --prefer-family=IPv4/IPv6/none
+When given a choice of several addresses, connect to the addresses
+with specified address family first. IPv4 addresses are preferred by
+default.
+
+This avoids spurious errors and connect attempts when accessing hosts
+that resolve to both IPv6 and IPv4 addresses from IPv4 networks. For
+example, @samp{www.kame.net} resolves to
+@samp{2001:200:0:8002:203:47ff:fea5:3085} and to
+@samp{203.178.141.194}. When the preferred family is @code{IPv4}, the
+IPv4 address is used first; when the preferred family is @code{IPv6},
+the IPv6 address is used first; if the specified value is @code{none},
+the address order returned by DNS is used without change.
+
+Unlike @samp{-4} and @samp{-6}, this option doesn't inhibit access to
+any address family, it only changes the @emph{order} in which the
+addresses are accessed. Also note that the reordering performed by
+this option is @dfn{stable}---it doesn't affect order of addresses of
+the same family. That is, the relative order of all IPv4 addresses
+and of all IPv6 addresses remains intact in all cases.
+
+@item --retry-connrefused
+Consider ``connection refused'' a transient error and try again.
+Normally Wget gives up on a URL when it is unable to connect to the
+site because failure to connect is taken as a sign that the server is
+not running at all and that retries would not help. This option is
+for mirroring unreliable sites whose servers tend to disappear for
+short periods of time.
+
+@cindex user
+@cindex password
+@cindex authentication
+@item --user=@var{user}
+@itemx --password=@var{password}
+Specify the username @var{user} and password @var{password} for both
+@sc{ftp} and @sc{http} file retrieval. These parameters can be overridden
+using the @samp{--ftp-user} and @samp{--ftp-password} options for
+@sc{ftp} connections and the @samp{--http-user} and @samp{--http-password}
+options for @sc{http} connections.
@end table
@node Directory Options
example, with this option, @samp{wget -r http://@var{host}} will save to
@samp{http/@var{host}/...} rather than just to @samp{@var{host}/...}.
-Disable generation of host-prefixed directories. By default, invoking
-Wget with @samp{-r http://fly.srk.fer.hr/} will create a structure of
-directories beginning with @file{fly.srk.fer.hr/}. This option disables
-such behavior.
-
@cindex cut directories
@item --cut-dirs=@var{number}
Ignore @var{number} directory components. This is useful for getting a
@cindex http password
@cindex authentication
@item --http-user=@var{user}
-@itemx --http-passwd=@var{password}
+@itemx --http-password=@var{password}
Specify the username @var{user} and password @var{password} on an
@sc{http} server. According to the type of the challenge, Wget will
encode them using either the @code{basic} (insecure) or the
really important, do not leave them lying in those files either---edit
the files and delete them after Wget has started the download.

@cindex session cookies
@item --keep-session-cookies

-supposed to be forgotten when you exit the browser. Saving them is

+meant to be kept in memory and forgotten when you exit the browser.
+Saving them is useful on sites that require you to log in or to visit
+the home page before you can access some pages. With this option,
+multiple Wget runs are considered a single browser session as far as
+the site is concerned.
Since the cookie file format does not normally carry session cookies,
Wget marks them with an expiry timestamp of 0. Wget's
if it never existed.
@cindex header, add
-@item --header=@var{additional-header}
-Define an @var{additional-header} to be passed to the @sc{http} servers.
-Headers must contain a @samp{:} preceded by one or more non-blank
-characters, and must not contain newlines.
+@item --header=@var{header-line}
+Send @var{header-line} along with the rest of the headers in each
+@sc{http} request. The supplied header is sent as-is, which means it
+must contain name and value separated by colon, and must not contain
+newlines.
You may define more than one additional header by specifying
@samp{--header} more than once.
Specification of an empty string as the header value will clear all
previous user-defined headers.
+As of Wget 1.10, this option can be used to override headers otherwise
+generated automatically. This example instructs Wget to connect to
+localhost, but to specify @samp{foo.bar} in the @code{Host} header:
+
+@example
+wget --header="Host: foo.bar" http://localhost/
+@end example
+
+In versions of Wget prior to 1.10 such use of @samp{--header} caused
+sending of duplicate headers.
+
@cindex proxy user
@cindex proxy password
@cindex proxy authentication
@item --proxy-user=@var{user}
-@itemx --proxy-passwd=@var{password}
+@itemx --proxy-password=@var{password}
Specify the username @var{user} and password @var{password} for
authentication on a proxy server. Wget will encode them using the
@code{basic} authentication scheme.
-Security considerations similar to those with @samp{--http-passwd}
+Security considerations similar to those with @samp{--http-password}
pertain here as well.
@cindex http referer
However, some sites have been known to impose the policy of tailoring
the output according to the @code{User-Agent}-supplied information.
-While conceptually this is not such a bad idea, it has been abused by
-servers denying information to clients other than @code{Mozilla} or
-Microsoft @code{Internet Explorer}. This option allows you to change
-the @code{User-Agent} line issued by Wget. Use of this option is
-discouraged, unless you really know what you are doing.
+While this is not such a bad idea in theory, it has been abused by

+Netscape or, more frequently, Microsoft Internet Explorer. This
+option allows you to change the @code{User-Agent} line issued by Wget.
+Use of this option is discouraged, unless you really know what you are
+doing.
+
+Specifying empty user agent with @samp{--user-agent=""} instructs Wget
+not to send the @code{User-Agent} header in @sc{http} requests.
@cindex POST
@item --post-data=@var{string}
can't know that until it receives a response, which in turn requires the
request to have been completed -- a chicken-and-egg problem.
-Note: if Wget is redirected after the POST request is completed, it will
-not send the POST data to the redirected URL. This is because URLs that
-process POST often respond with a redirection to a regular page
-(although that's technically disallowed), which does not desire or
-accept POST. It is not yet clear that this behavior is optimal; if it
-doesn't work out, it will be changed.

@end group
@end example
+
+If the server is using session cookies to track user authentication,
+the above will not work because @samp{--save-cookies} will not save
+them (and neither will browsers) and the @file{cookies.txt} file will
+be empty. In that case use @samp{--keep-session-cookies} along with
+@samp{--save-cookies} to force saving of session cookies.
+@end table
+
+@node HTTPS (SSL/TLS) Options
+@section HTTPS (SSL/TLS) Options
+
+@cindex SSL
+To support encrypted HTTP (HTTPS) downloads, Wget must be compiled
+with an external SSL library, currently OpenSSL. If Wget is compiled
+without SSL support, none of these options are available.
+
+@table @samp
+@cindex SSL protocol, choose
+@item --secure-protocol=@var{protocol}
+Choose the secure protocol to be used. Legal values are @samp{auto},
+@samp{SSLv2}, @samp{SSLv3}, and @samp{TLSv1}. If @samp{auto} is used,
+the SSL library is given the liberty of choosing the appropriate
+protocol automatically, which is achieved by sending an SSLv2 greeting
+and announcing support for SSLv3 and TLSv1. This is the default.
+
+Specifying @samp{SSLv2}, @samp{SSLv3}, or @samp{TLSv1} forces the use
+of the corresponding protocol. This is useful when talking to old and
+buggy SSL server implementations that make it hard for OpenSSL to
+choose the correct protocol version. Fortunately, such servers are
+quite rare.
+
+@cindex SSL certificate, check
+@item --no-check-certificate
+Don't check the server certificate against the available certificate
+authorities. Also don't require the URL host name to match the common
+name presented by the certificate.
+
+As of Wget 1.10, the default is to verify the server's certificate
+against the recognized certificate authorities, breaking the SSL
+handshake and aborting the download if the verification fails.
+Although this provides more secure downloads, it does break
+interoperability with some sites that worked with previous Wget
+versions, particularly those using self-signed, expired, or otherwise
+invalid certificates. This option forces an ``insecure'' mode of
+operation that turns the certificate verification errors into warnings
+and allows you to proceed.
+
+If you encounter ``certificate verification'' errors or ones saying
+that ``common name doesn't match requested host name'', you can use
+this option to bypass the verification and proceed with the download.
+@emph{Only use this option if you are otherwise convinced of the
+site's authenticity, or if you really don't care about the validity of
+its certificate.} It is almost always a bad idea not to check the
+certificates when transmitting confidential or important data.
+
+@cindex SSL certificate
+@item --certificate=@var{file}
+Use the client certificate stored in @var{file}. This is needed for
+servers that are configured to require certificates from the clients
+that connect to them. Normally a certificate is not required and this
+switch is optional.
+
+@cindex SSL certificate type, specify
+@item --certificate-type=@var{type}
+Specify the type of the client certificate. Legal values are
+@samp{PEM} (assumed by default) and @samp{DER}, also known as
+@samp{ASN1}.
+
+@item --private-key=@var{file}
+Read the private key from @var{file}. This allows you to provide the
+private key in a file separate from the certificate.
+
+@item --private-key-type=@var{type}
+Specify the type of the private key. Accepted values are @samp{PEM}
+(the default) and @samp{DER}.
+
+@item --ca-certificate=@var{file}
+Use @var{file} as the file with the bundle of certificate authorities
+(``CA'') to verify the peers. The certificates must be in PEM format.
+
+Without this option Wget looks for CA certificates at the
+system-specified locations, chosen at OpenSSL installation time.
+
+@cindex SSL certificate authority
+@item --ca-directory=@var{directory}
+Specifies directory containing CA certificates in PEM format. Each
+file contains one CA certificate, and the file name is based on a hash
+value derived from the certificate. This is achieved by processing a
+certificate directory with the @code{c_rehash} utility supplied with
+OpenSSL. Using @samp{--ca-directory} is more efficient than
+@samp{--ca-certificate} when many certificates are installed because
+it allows Wget to fetch certificates on demand.
+
+Without this option Wget looks for CA certificates at the
+system-specified locations, chosen at OpenSSL installation time.
+
+@cindex entropy, specifying source of
+@cindex randomness, specifying source of
+@item --random-file=@var{file}
+Use @var{file} as the source of random data for seeding the
+pseudo-random number generator on systems without @file{/dev/random}.
+
+On such systems the SSL library needs an external source of randomness
+to initialize. Randomness may be provided by EGD (see
+@samp{--egd-file} below) or read from an external source specified by
+the user. If this option is not specified, Wget looks for random data
+in @code{$RANDFILE} or, if that is unset, in @file{$HOME/.rnd}. If
+none of those are available, it is likely that SSL encryption will not
+be usable.
+
+If you're getting the ``Could not seed OpenSSL PRNG; disabling SSL.''
+error, you should provide random data using some of the methods
+described above.
+
+@cindex EGD
+@item --egd-file=@var{file}
+Use @var{file} as the EGD socket. EGD stands for @dfn{Entropy
+Gathering Daemon}, a user-space program that collects data from
+various unpredictable system sources and makes it available to other
+programs that might need it. Encryption software, such as the SSL
+library, needs sources of non-repeating randomness to seed the random
+number generator used to produce cryptographically strong keys.
+
+OpenSSL allows the user to specify his own source of entropy using the
+@code{RAND_FILE} environment variable. If this variable is unset, or
+if the specified file does not produce enough randomness, OpenSSL will
+read random data from EGD socket specified using this option.
+
+If this option is not specified (and the equivalent startup command is
+not used), EGD is never contacted. EGD is not needed on modern Unix
+systems that support @file{/dev/random}.

@table @samp
+@cindex ftp user
+@cindex ftp password
+@cindex ftp authentication
+@item --ftp-user=@var{user}
+@itemx --ftp-password=@var{password}
+Specify the username @var{user} and password @var{password} on an
+@sc{ftp} server. Without this, or the corresponding startup option,
+the password defaults to @samp{-wget@@}, normally used for anonymous
+FTP.
+
+Another way to specify username and password is in the @sc{url} itself
+(@pxref{URL Format}). Either method reveals your password to anyone who
+bothers to run @code{ps}. To prevent the passwords from being seen,
+store them in @file{.wgetrc} or @file{.netrc}, and make sure to protect
+those files from other users with @code{chmod}. If the passwords are
+really important, do not leave them lying in those files either---edit
+the files and delete them after Wget has started the download.

@cindex .listing files, removing
@item --no-remove-listing
Don't remove the temporary @file{.listing} files generated by @sc{ftp}
servers (and the ones emulating Unix @code{ls} output).
@cindex passive ftp
-@item --passive-ftp
-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.
+@item --no-passive-ftp
+Disable the use of the @dfn{passive} FTP transfer mode. Passive FTP
+mandates that the client connect to the server to establish the data
+connection rather than the other way around.
+
+If the machine is connected to the Internet directly, both passive and
+active FTP should work equally well. Behind most firewall and NAT
+configurations passive FTP has a better chance of working. However,
+in some rare firewall configurations, active FTP actually works when
+passive FTP doesn't. If you suspect this to be the case, use this
+option, or set @code{passive_ftp=off} in your init file.
@cindex symbolic links, retrieving
@item --retr-symlinks
specified on the command-line, rather than because it was recursed to,
this option has no effect. Symbolic links are always traversed in this
case.
+
+@cindex Keep-Alive, turning off
+@cindex Persistent Connections, disabling
+@item --no-http-keep-alive
+Turn off the ``keep-alive'' feature for HTTP downloads. Normally, Wget
+asks the server to keep the connection open so that, when you download
+more than one document from the same server, they get transferred over
+the same TCP connection. This saves time and at the same time reduces
+the load on the server.
+
+This option is useful when, for some reason, persistent (keep-alive)
+connections don't work for you, for example due to a server bug or due
+to the inability of server-side scripts to cope with the connections.

+Various Wget versions have been compiled and tested under many kinds
+of Unix systems, including GNU/Linux, Solaris, SunOS 4.x, OSF (aka
+Digital Unix or Tru64), Ultrix, *BSD, IRIX, AIX, and others. Some of
+those systems are no longer in widespread use and may not be able to
+support recent versions of Wget. If Wget fails to compile on your
+system, we would like to know about it.
+
+Thanks to kind contributors, this version of Wget compiles and works
+on 32-bit Microsoft Windows platforms. It has been compiled
+successfully using MS Visual C++ 6.0, Watcom, Borland C, and GCC
+compilers. Naturally, it is crippled of some features available on
+Unix, but it should work as a substitute for people stuck with
+Windows. Note that Windows-specific portions of Wget are not
+guaranteed to be supported in the future, although this has been the
+case in practice for many years now. All questions and problems in
+Windows usage should be reported to Wget mailing list at
@email{wget@@sunsite.dk} where the volunteers who maintain the
Windows-related features might look at them.
to redirect the output of Wget after having started it.
@example
-$ wget http://www.ifi.uio.no/~larsi/gnus.tar.gz &
-$ kill -HUP %% # Redirect the output to wget-log
+$ wget http://www.gnus.org/dist/gnus.tar.gz &
+...
+$ kill -HUP %%
+SIGHUP received, redirecting output to `wget-log'.
@end example
Other than that, Wget will not try to interfere with signals in any way.

-The best way around it is to use @code{wget -i -} and feed the @sc{url}s
