I am trying to create an alias/bash script that will use apt to fully upgrade all applications on my computer as a background process.   But for some reason, later parts of the standard out appear to be printing to the main commandline, even if I spawn an entirely different bash instance and disown my script  bred@loaf:~$ alias aptup='sudo apt-get update &gt; ~/aptlog &amp;&amp; sudo apt-get dist-upgrade &gt;&gt; ~/aptlog &amp;&amp; sudo apt-get upgrade &gt;&gt; ~/aptlog &amp;' bred@loaf:~$ aptup [1] 24361 bred@loaf:~$ Starting pkgProblemResolver with broken count: 0 Starting 2 pkgProblemResolver with broken count: 0 Done Entering ResolveByKeep ^C [1]+  Done                    sudo apt-get update &gt; ~/aptlog &amp;&amp; sudo apt-get dist-upgrade &gt;&gt; ~/aptlog &amp;&amp; sudo apt-get upgrade &gt;&gt; ~/aptlog    bred@loaf:~$ alias aptup="sudo bash -c 'apt-get update &gt; ~/aptlog &amp;&amp; apt-get dist-upgrade &gt;&gt; ~/aptlog &amp;&amp; apt-get upgrade &gt;&gt; ~/aptlog &amp; disown'" bred@loaf:~$ aptup bred@loaf:~$ Starting pkgProblemResolver with broken count: 0 Starting 2 pkgProblemResolver with broken count: 0 Done Entering ResolveByKeep ^C bred@loaf:~$    Note the "^C" is me using Ctrl+C to exit the process and regain control because the task is done.  EDIT: Also, I should be running the  --yes --force-yes   tags on each of the upgrade commands so that apt has permission to do upgrades if there are any. But the same result occurs nonetheless
For example, when I type ping 8.8.8.8 &amp;, why can we see ping process working? And when I type find / -name '*test*' &amp; , it's also seen on monitor.  Why is that? Is it not really in background?

I have a field named Payment due date. is it possible to trigger an email 2 days prior to the Payment due date. So that I don't miss the payment due date and payment is not delayed. Any kind of assistance is appreciated. Thank you very much in advance! Given the functional dependencies of a relation is there more then one way to normalize it? Manually installing a program on Debian How can I add an empty directory to a Git repository? How can I add an empty directory (that contains no files) to a Git repository? Why do diamonds shine? I have always wondered why diamonds shine. Can anyone tell me why? I'm being asked to determine if $\displaystyle\sum\limits_{n=3}^\infty \frac1{n (\ln n)\ln(\ln n)}$ converges. So, using Cauchy's Condensation Test, I reduced the problem to one of determining the convergence of $\displaystyle\sum\limits_{n=3}^\infty\frac 1{n\ln (n\ln 2)}$. Am I on the right path, and how do I proceed from here? Stein's lemma condition (Apologies if I break some conventions, this is my first time posting!)  I am working on proving Stein's characterization of the Normal distribution: for Z $\sim N(0,1)$ and some differentiable function $f$ with $E[|f'(Z)|] &lt; \infty$, $$E[Zf(Z)] = E[f'(Z)]$$ Writing the LHS expression in integral form and integrating by parts, I eventually obtain: $$E[Zf(Z)] = \frac{1}{\sqrt{2\pi}} \left[ -f(z) \cdot \exp \left\{ \frac{-z^2}{2} \right\} \right] \Bigg|_{-\infty}^{\infty} + E[f'(Z)]$$ Now I need to show that the first expression on the right hand size is zero. Intuitively, this seems clear because of the exponential term, but I am having trouble explicitly applying the condition on $f'$ to prove this rigorously. Any ideas?

What I am missing?   Thanks in Advance!! I understand the idea of a focal length for a single lens, i e the distance from the lens to the point at which parallel rays of light converge. However, in the case of a photographic lens with multiple lens elements, where exactly is the focal length of the lens as a whole measured from? What is the difference between the displace socket and a bump map? Aside from the fact that you can control the bump mapping per shader with a bump node, are there any differences between these materials?      As far  as I can tell, they are the same. Is the displacement socket just a convenience thing? Is there a performance advantage? Is it possible to print a variable's type in standard C++?

For testing purposes, I want to install two different instances of firefox on ubuntu - so that they don't share cookies.

Any point to downvoting already closed questions? That question of mine was closed a long time ago (relatively, to me at least).  However, from time to time I still get downvotes for it.  That got me thinking: is there any reason to still downvote closed questions? Proving that $T^{2} = T$ for a linear operator on $W$ implies that $V = \operatorname{Null} T \oplus \operatorname{Range} T$
