I'm trying to output the document body and its headers to STDOUT by doing
wget -S -O - http://google.com
...but it shows only the HTML document.
Update: Got it to work with
wget --save-headers --output-document - http://google.com
wget --version shows my version is GNU Wget 1.11.4 Red Hat modified.
Try the following, no extra headers
wget -qO- www.google.com
Note the trailing -. This is part of the normal command argument for -O to cat out to a file, but since we don't use > to direct to a file, it goes out to the shell. You can use -qO- or -qO -.
This worked for me for printing response with header:
wget --server-response http://www.example.com/
It works here:
$ wget -S -O - http://google.com

perhaps you need to update your wget (~$ wget --version
GNU Wget 1.14 built on linux-gnu.)
This will not work:
wget -q -S -O - google.com 1>wget.txt 2>&1
since redirects are evaluated right to left, this sends html to wget.txt and the header to STDOUT:
wget -q -S -O - google.com 2>&1 1>wget.txt
wget -S -O - http://google.com works as expected for me, but with a caveat: the headers are considered debugging information and as such they are sent to the standard error rather than the standard output. If you are redirecting the standard output to a file or another process, you will only get the document contents.
You can try redirecting the standard error to the standard output as a possible solution. For example, in bash:
$ wget -q -S -O - 2>&1 | grep ...
or
$ wget -q -S -O - 1>wget.txt 2>&1
The -q option suppresses the progress bar and some other annoyingly chatty parts of the wget output.
