<div dir="ltr">I am writing someone a letter. He has script that
runs apt-get update/grade in one swoop. Something happened once
and he needed to see what files had upgraded but because nothing
print to screen he had no idea which files did. Could someone
tell me if I am telling it correctly? In the unfinished
paragraph I am unsure how to finish it. What I want to do is
prepend 'file' with the date. How is it done?

<p style="margin:0px;font-family:'Helvetica

wiz, you might want to make your script print the output
of update/upgrade to a file in case something like this
happens again and you need to see what it did. You do this
by typing:</p>
<p style="margin:0px;font-family:'Helvetica
Neue',Arial,Verdana,sans-serif;font-size:14px"><br>
</p>
<p style="margin:0px;font-family:'Helvetica
Neue',Arial,Verdana,sans-serif;font-size:14px"> sudo
apt-get update > file</p>
<p style="margin:0px;font-family:'Helvetica
Neue',Arial,Verdana,sans-serif;font-size:14px"> sudo
apt-get upgrade >> file</p>
<p style="margin:0px;font-family:'Helvetica
Neue',Arial,Verdana,sans-serif;font-size:14px"><br>
</p>
<p style="margin:0px;font-family:'Helvetica
Neue',Arial,Verdana,sans-serif;font-size:14px">If you want
it to print any errors that may have scrolled by to the
file you'll have to pre-pend the carrots with '&2' to
make it look like this:</p>
<p style="margin:0px;font-family:'Helvetica
Neue',Arial,Verdana,sans-serif;font-size:14px"><br>
</p>
<p style="margin:0px;font-family:'Helvetica
Neue',Arial,Verdana,sans-serif;font-size:14px"> sudo
apt-get update &2> file</p>
<p style="margin:0px;font-family:'Helvetica
Neue',Arial,Verdana,sans-serif;font-size:14px">and </p>
<p style="margin:0px;font-family:'Helvetica
Neue',Arial,Verdana,sans-serif;font-size:14px"> sudo
apt-get upgrade &2>> file</p>
<p style="margin:0px;font-family:'Helvetica
Neue',Arial,Verdana,sans-serif;font-size:14px"><br>
</p>
<p style="margin:0px;font-family:'Helvetica
Neue',Arial,Verdana,sans-serif;font-size:14px">I'm pretty
sure that is how it is done at least. I wouldn't worry
about making 'file' unique for each time you run it as
you'll never look at it unless there is a problem. If you
really want to do that </p>
