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 Turn on debug output, meaning various information important to the developers of Wget if it does not work properly.
” is actually a misnomer in this mode—it’s not clobbering that’s prevented (as the numeric suffixes were already preventing clobbering), but rather the multiple version saving that’s prevented.When running Wget with ‘ in the current directory, Wget will assume that it is the first portion of the remote file, and will ask the server to continue the retrieval from an offset equal to the length of the local file.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. ‘’ on a non-empty file, and the server does not support continued downloading, Wget will restart the download from scratch and overwrite the existing file entirely.This file documents the GNU Wget utility for downloading network data.Copyright © 1996, 1997, 1998, 1999, 2000, 2001, 2002, 2003, 2004, 2005, 2006, 2007, 2008, 2009, 2010, 2011, 2015 Free Software Foundation, Inc.

If you do not understand the difference between these notations, or do not know which one to use, just use the plain ordinary format you use with your favorite browser, like 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. Unless stated otherwise, it is assumed that the default behavior is the opposite of what the option accomplishes.
You may freely mix different option styles, or specify options after the command-line arguments. For example, the documented existence of ‘’ prefix.
