Download Options

`-t number'

`--tries=number'

Set number of retries to number. Specify 0 or `inf' for infinite retrying.

`-O file'

`--output-document=file'

The documents will not be written to the appropriate files, but all will be concatenated together and written to file. If file already exists, it will be overwritten. If the file is `-', the documents will be written to standard output. Including this option automatically sets the number of tries to 1.

`-nc'

`--no-clobber'

Do not clobber existing files when saving to directory hierarchy within recursive retrieval of several files. This option is extremely useful when you wish to continue where you left off with retrieval of many files. If the files have the `.html' or (yuck) `.htm' suffix, they will be loaded from the local disk, and parsed as if they have been retrieved from the Web.

`-c'

`--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:

wget -c ftp://sunsite.doc.ic.ac.uk/ls-lR.Z

If there is a file name `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 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 FTP client, or left by Wget being killed. Without `-c', the previous example would just begin to download the remote file to `ls-lR.Z.1'. The `-c' option is also applicable for HTTP servers that support the Range header.

`--dot-style=style'

Set the retrieval style to 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 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 default style each dot represents 1K, there are ten dots in a cluster and 50 dots in a line. The binary style has a more "computer"-like orientation--8K dots, 16-dots clusters and 48 dots per line (which makes for 384K lines). The 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 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.

`-N'

`--timestamping'

Turn on time-stamping. See section Time-Stamping for details.

`-S'

`--server-response'

Print the headers sent by HTTP servers and responses sent by FTP servers.

`--spider'

When invoked with this option, Wget will behave as a Web spider, which means that it will not download the pages, just check that they are there. You can use it to check your bookmarks, e.g. with:

wget --spider --force-html -i bookmarks.html

This feature needs much more work for Wget to get close to the functionality of real WWW spiders.

`-T seconds'

`--timeout=seconds'

Set the read timeout to seconds seconds. Whenever a network read is issued, the file descriptor is checked for a timeout, which could otherwise leave a pending connection (uninterrupted read). The default timeout is 900 seconds (fifteen minutes). Setting timeout to 0 will disable checking for timeouts. Please do not lower the default timeout value with this option unless you know what you are doing.

`-w seconds'

`--wait=seconds'

Wait the specified number of seconds between the retrievals. Use of this option is recommended, as it lightens the server load by making the requests less frequent. Instead of in seconds, the time can be specified in minutes using the m suffix, in hours using h suffix, or in days using d suffix. Specifying a large value for this option is useful if the network or the destination host is down, so that Wget can wait long enough to reasonably expect the network error to be fixed before the retry.

`-Y on/off'

`--proxy=on/off'

Turn proxy support on or off. The proxy is on by default if the appropriate environmental variable is defined.

`-Q quota'

`--quota=quota'

Specify download quota for automatic retrievals. The value can be specified in bytes (default), kilobytes (with `k' suffix), or megabytes (with `m' suffix). Note that quota will never affect downloading a single file. So if you specify `wget -Q10k ftp://wuarchive.wustl.edu/ls-lR.gz', all of the `ls-lR.gz' will be downloaded. The same goes even when several URLs are specified on the command-line. However, quota is respected when retrieving either recursively, or from an input file. Thus you may safely type `wget -Q2m -i sites'---download will be aborted when the quota is exceeded. Setting quota to 0 or to `inf' unlimits the download quota.
