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 docum

    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

    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.)

    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 -.

    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.

    This worked for me for printing response with header: 

    wget --server-response http://www.example.com/
