wget: Logging and Input File Options
2.4 Logging and Input File Options
==================================
‘-o LOGFILE’
‘--output-file=LOGFILE’
Log all messages to LOGFILE. The messages are normally reported to
standard error.
‘-a LOGFILE’
‘--append-output=LOGFILE’
Append to LOGFILE. This is the same as ‘-o’, only it appends to
LOGFILE instead of overwriting the old log file. If LOGFILE does
not exist, a new file is created.
‘-d’
‘--debug’
Turn on debug output, meaning various information important to the
developers of Wget if it does not work properly. Your system
administrator may have chosen to compile Wget without debug
support, in which case ‘-d’ will not work. Please note that
compiling with debug support is always safe—Wget compiled with the
debug support will _not_ print any debug info unless requested with
‘-d’. ⇒Reporting Bugs, for more information on how to use
‘-d’ for sending bug reports.
‘-q’
‘--quiet’
Turn off Wget’s output.
‘-v’
‘--verbose’
Turn on verbose output, with all the available data. The default
output is verbose.
‘-nv’
‘--no-verbose’
Turn off verbose without being completely quiet (use ‘-q’ for
that), which means that error messages and basic information still
get printed.
‘--report-speed=TYPE’
Output bandwidth as TYPE. The only accepted value is ‘bits’.
‘-i FILE’
‘--input-file=FILE’
Read URLs from a local or external FILE. If ‘-’ is specified as
FILE, URLs are read from the standard input. (Use ‘./-’ to read
from a file literally named ‘-’.)
If this function is used, no URLs need be present on the command
line. If there are URLs both on the command line and in an input
file, those on the command lines will be the first ones to be
retrieved. If ‘--force-html’ is not specified, then FILE should
consist of a series of URLs, one per line.
However, if you specify ‘--force-html’, the document will be
regarded as ‘html’. In that case you may have problems with
relative links, which you can solve either by adding ‘<base
href="URL">’ to the documents or by specifying ‘--base=URL’ on the
command line.
If the FILE is an external one, the document will be automatically
treated as ‘html’ if the Content-Type matches ‘text/html’.
Furthermore, the FILE’s location will be implicitly used as base
href if none was specified.
‘--input-metalink=FILE’
Downloads files covered in local Metalink FILE. Metalink version 3
and 4 are supported.
‘--keep-badhash’
Keeps downloaded Metalink’s files with a bad hash. It appends
.badhash to the name of Metalink’s files which have a checksum
mismatch, except without overwriting existing files.
‘--metalink-over-http’
Issues HTTP HEAD request instead of GET and extracts Metalink
metadata from response headers. Then it switches to Metalink
download. If no valid Metalink metadata is found, it falls back to
ordinary HTTP download. Enables ‘Content-Type:
application/metalink4+xml’ files download/processing.
‘--metalink-index=NUMBER’
Set the Metalink ‘application/metalink4+xml’ metaurl ordinal
NUMBER. From 1 to the total number of “application/metalink4+xml”
available. Specify 0 or ‘inf’ to choose the first good one.
Metaurls, such as those from a ‘--metalink-over-http’, may have
been sorted by priority key’s value; keep this in mind to choose
the right NUMBER.
‘--preferred-location’
Set preferred location for Metalink resources. This has effect if
multiple resources with same priority are available.
‘--xattr’
Enable use of file system’s extended attributes to save the
original URL and the Referer HTTP header value if used.
Be aware that the URL might contain private information like access
tokens or credentials.
‘-F’
‘--force-html’
When input is read from a file, force it to be treated as an HTML
file. This enables you to retrieve relative links from existing
HTML files on your local disk, by adding ‘<base href="URL">’ to
HTML, or using the ‘--base’ command-line option.
‘-B URL’
‘--base=URL’
Resolves relative links using URL as the point of reference, when
reading links from an HTML file specified via the
‘-i’/‘--input-file’ option (together with ‘--force-html’, or when
the input file was fetched remotely from a server describing it as
HTML). This is equivalent to the presence of a ‘BASE’ tag in the
HTML input file, with URL as the value for the ‘href’ attribute.
For instance, if you specify ‘http://foo/bar/a.html’ for URL, and
Wget reads ‘../baz/b.html’ from the input file, it would be
resolved to ‘http://foo/baz/b.html’.
‘--config=FILE’
Specify the location of a startup file you wish to use instead of
the default one(s). Use –no-config to disable reading of config
files. If both –config and –no-config are given, –no-config is
ignored.
‘--rejected-log=LOGFILE’
Logs all URL rejections to LOGFILE as comma separated values. The
values include the reason of rejection, the URL and the parent URL
it was found in.
