+@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.

@item dot_spacing = @var{n}
Specify the number of dots in a single cluster (10 by default).
-@item dot_style = @var{string}
-Specify the dot retrieval @dfn{style}, as with @samp{--dot-style}.
-
@item exclude_directories = @var{string}
Specify a comma-separated list of directories you wish to exclude from
download---the same as @samp{-X} (@pxref{Directory-Based Limits}).
Same as @samp{--exclude-domains} (@pxref{Domain Acceptance}).
@item follow_ftp = on/off

@item follow_tags = @var{string}
Only follow certain HTML tags when doing a recursive retrieval, just like
Set your @sc{ftp} password to @var{password}. Without this setting, the
password defaults to @samp{username@@hostname.domainname}.
+@item progress = @var{string}
+Set the type of the progress indicator. Legal types are ``dot'' and
+``bar''.
+
@item proxy_user = @var{string}
Set proxy authentication user name to @var{string}, like @samp{--proxy-user}.
Wait up to @var{n} seconds between retries of failed retrievals
only---the same as @samp{--waitretry}. Note that this is turned on by
default in the global @file{wgetrc}.
+
+@item randomwait = on/off
+Turn random between-request wait times on or off. The same as
+@samp{--random-wait}.

+This variable should contain the @sc{url} of the proxy for @sc{ftp}
connections. It is quite common that @sc{http_proxy} and @sc{ftp_proxy}
are set to the same @sc{url}.
You may specify your username and password either through the proxy
@sc{url} or through the command-line options. Assuming that the

-Wget is @dfn{free software}, where ``free'' refers to liberty, not
-price. As the GNU people like to say, think of ``free speech'' rather
-than ``free beer''. The exact legal distribution terms follow below,
-but in short, you have the right (freedom) to run and change Wget and
-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
-your recipients the same rights.
-
-This method of licensing software is also known as @dfn{open-source},
-because it requires that the recipients always receive a program's
-source code along with the program.
