resolving basic authentication problem(401) with wget

I have a server with a php requiring basic authentication, like this:

header('WWW-Authenticate: Basic realm="do auth"');

header('HTTP/1.0 401 Unauthorized');

...?>

And the basic authentication in wget do not worked:

wget --auth-no-challenge --http-user="username" --http-password="password" -O- "http://url"

wget --keep-session-cookies --save-cookies=cookies.txt --load-cookies=cokies.txt --http-user="username" --http-password="password" -O- "http://url"

I always received the 401 Authorization failed.

The saved cookie is always empty.

With my way, I received the header from the server and save the cookie, then resend the session cookie with authentication data

get stdout to variable and stdout at sametime

Sometimes you want to write the script output to stdout but you need to send it to email.

If you use:

var="$( ls / )"; echo -e "$var";

works but, you need to wait the script terminate to bufferize then print the output var;

With this way, you can use/work/print the output before the variable receive all the output content, then after it you can use the variable for anything else, like send email.
