-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 - is used as
file, documents will
be printed to standard output, disabling link conversion.
(Use ./- to print to a
file literally named -.)
Use of -O is not intended to mean simply "use the name file
instead of the one in
the URL;" rather, it is analogous to shell redirection:
wget -O file http://foo is
intended to work like wget -O - http://foo > file; file
will be truncated
immediately, and all downloaded content will be written there.
For this reason, -N (for timestamp-checking) is not
supported in combination with
-O: since file is always newly created, it will always have
a very new timestamp.
A warning will be issued if this combination is used.
Similarly, using -r or -p with -O may not work as you
expect: Wget won't just
download the first file to file and then download the rest
to their normal names:
all downloaded content will be placed in file. This was
disabled in version 1.11,
but has been reinstated (with a warning) in 1.11.2, as
there are some cases where
this behavior can actually have some use.
Note that a combination with -k is only permitted when
downloading a single
document, as in that case it will just convert all relative
URIs to external ones;
-k makes no sense for multiple URIs when they're all being
downloaded to a single
file.
