Hi there, please could you assist me. I have no knowledge at all about Unix and I have applied for a job and they have given me a test and said that I can obtain the answers in any kind of way. There are 3 questions that I need answers for. I have tried researching the answers to these questions but cannot find them. There were a few other questions which I have answered by doing research but no luck with these. These are the 3 questions below.
1.What does the following command do
Code:
"FILE[2]=file1.txt;
CNTR=2;
if [ ! -f "${FILE[$CNTR]}" ];
then
echo yes;
else
echo no;
fi"
2. What does the following command do
Code:
cat file1.txt | sed '1d;$d'
3. Please supply the Sybase sql command used to restore a database called test.dmp which was
dumped with compression ratio 3

Good Afternoon,
Are most NASs compatible with Solaris/RedHat? Specifically, I'm looking at Western Digital ones but none of them say they are - I like My Cloud Pro Series PR4100

dpkg-preconfigure
DPKG-PRECONFIGURE(8) Debconf DPKG-PRECONFIGURE(8)NAME
dpkg-preconfigure - let packages ask questions prior to their installation
SYNOPSIS
dpkg-preconfigure [options] package.deb
dpkg-preconfigure --apt
DESCRIPTION
dpkg-preconfigure lets packages ask questions before they are installed. It operates on a set of debian packages, and all packages that
use debconf will have their config script run so they can examine the system and ask questions.
OPTIONS -ftype, --frontend=type
Select the frontend to use.
-pvalue, --priority=value
Set the lowest priority of questions you are interested in. Any questions with a priority below the selected priority will be ignored
and their default answers will be used.
--terse
Enables terse output mode. This affects only some frontends.
--apt
Run in apt mode. It will expect to read a set of package filenames from stdin, rather than getting them as parameters. Typically this
is used to make apt run dpkg-preconfigure on all packages before they are installed. To do this, add something like this to
/etc/apt/apt.conf:
// Pre-configure all packages before
// they are installed.
DPkg::Pre-Install-Pkgs {
"dpkg-preconfigure --apt --priority=low";
};
-h, --help
Display usage help.
