I recommend another "Debian Study Notes"

In the past two days, the Oracle Application Server seems to be relatively stable and no other chores bother me. So, take some time to prepare your own test environment, you can do some small experiments on it. But there is a feeling that this is the silence before the storm comes. It took two days to install Debian twice. I was familiar with the installation and configuration. Some specific Debian operations, such as apt-Get, are basically mastered. In fact, I usually reject proprietary operation commands, which will bind people to a specific platform. However, on the Internet, we can see that APT is also available on Redhat and ubuntu. Now the operation is basically the same as the operation in the original rehl, and there is no difference. The use of Linux is quite different from the use of Linux two years ago. The previous focus is on applications. Now, the first focus is security, followed by management and configuration. I recommend a good article, which is more detailed. After reading the article, I found that I ignored some details. Debian Study Notes : Sorting: JimsFat family Today, we upgraded the Debian kernel, routinely installed JDK, downloaded eclipse3.1.2, and ran normally.
A few days ago, I also found some records of log files in Linux and analyzed the articles. Next, I plan to configure iptables first, and then install a new function in Oracle 10g testing, the management of oralce is also my concern and a major direction.
I also found several common commands in Linux, which were also available in windows, such as grep. It seems that I have seen them before, but I forgot it later. They are all very convenient commands. However, there are also many commands, which are quite different from those in windows. For example, the shell programming part is really completely new to learning a new syntax. The more I learn, the more chaotic I seem to be. If I ask that function to get the current date, I have to ask what kind of environment I want? Windows? Linux? Oracle? Sqlserver? Delphi? C #? VC? ... Then, I need to check the help to answer.
