One of the Linux operation and Learning notes: the principles of operational dimension and learning methods __linux

has been using Linux, but never studied the system, starting from January 1 to the end of July 16, nearly seven months of study, so that since the Linux has a new understanding of the old boy teacher's class is really good, the actual combat is very strong. Since only noon and evening after 10 o'clock to have time, so all the experiments are done on different computers, the text of IP may have a problem, but should not affect the experiment. At the same time, in order to ensure the integrity of the notes, when taking notes, from the Internet also downloaded some pictures and content. the principle of the first Zhang YUNWI: one, simple , easy to use, efficient second, make backup before modification 1. To roll back 2, in order to later than the rehabilitation of the inside third, the principle of minimizing 1. Minimum installation system 2, the opening of services to minimize 3, the operation of minimizing

Rm-fr Test.txt more R, just delete file, should be rm-f test.txt 4, landing minimized

    do not need to log in at ordinary times, to log on with normal users 5, permissions to minimize 6, configure parameters to be reasonable, do not maximize four, Try to walk the way others walk, the probability of a small problem (operation Dimension requirements Stable)
Chapter Two learning methods First, in use memory Two, summarize the technical points through the case Third, drawing to remember knowledge points, make knowledge easier, easy to remember four, when a command output, contains the content of the need, to think that this command may have the corresponding parameters directly show what we need v. Learn to make a summary, to draw conclusions after practice Six, through examples or cases to remember the conclusion seven, try to use man to view Help, do not look at second-hand materials. The man command allows you to view not only commands but also the help of a process. Eight, speak with data, draw conclusions with actual tests nine, when deployed correctly, you can toss a point, let the system error, improve the ability to solve the failure 10, first pass the road, Work more with 11 and make good practices a big deal. 12, some questions and suggestions for beginners to learn Linux operation and maintenance.
