Pre-Job 3 Linux installation and learning to install virtual machines

Before the Win7 system through the EASYBCD installed Ubuntu virtual machine, this reading "Based on VirtualBox virtual machine installation Ubuntu Graphics Tutorial" and learned a new method.

• Issue: The latest version of Ubuntu is updated with different installation options.

• Workaround: The latest version of Baidu installation method.

  The Linux command Learning course Linux Basics Primer (new version) is very detailed and gives me a lot of insight and a deeper understanding of Linux systems.
• Problems encountered and how to solve them
  • Memorization of commands is easy to forget, and is not conducive to understanding: the use of experiments and practical use of commands to deepen understanding, rather than only by reciting, but also learn to use MAN,HELP and other commands to help themselves.
  • The learning process needs to be applied to vim, but no contact: the course is attached with VIM's learning course address and is studied through the course.
  • Learning process only pay attention to the command and other learning, but in the test appears similar to the UNIX and C language of the father who this common sense has been neglected, for the FHS standard has a certain concept but not accurate memory, the face of the choice problem feeling are specious: re-review by their own omission but the basic knowledge, accurate memory understanding, Rather than a memory that is taken for granted.
• Learning Summary

2. Linux Learning Core I think that is to understand the Linux operating system and we know the difference between the Windows system, understand the FHS standard: FHS defines the two layer specification, the first layer is,/below the directory should be put what file data, such as/etc should be placed in the settings file,/bin and/ Sbin should place executable files and so on. The second tier is defined for sub-directories of the/USR and/var directories. For example,/var/log places system login files,/usr/share places shared data, and so on.
   
   
   Only by learning these, can you understand the abstract concepts of Linux command mode and mount
4. Linux Command learning:, the Blog Park in the course is more comprehensive, but in fact, the use of the process will find that the actual operation to grasp the understanding. The course simply explains the general usage of the main commands, and in fact we will need to apply more [option] parameters even if we just use these main commands. Command line Learning There is no shortcut, only through the practice, using the network to find or use the man and other help command or use cheat, such as a further study, the teacher led the door, practice on the individual . And I think the delicate linux command line, and our Windows CMD and so the most different more body now the use of regular expressions and pipelines, making the command extremely flexible and practical. And the importance of practice is the most intuitive embodiment is in the current study, the beginning often in the use of the command some vague impression, but not sure, the need to rely on tab completion or note or man and other help commands can be determined, but multiple occurrences of the command gradually can not rely on external forces can be independent implementation.
6. Linux individual learning problems and problems: a. For Linux only in the experimental building according to the tutorial did some experiments and work, for some of the more abstract image of the backup mount, etc., not understanding. For the importance of the log and the role of a certain understanding, but for specific when to use, how to use it to solve the problem of computer, the specific use of the relevant commands are not a special understanding. B. The regular expression and other commands in the objective has not been able to skillfully use, but believe in the learning process of conscious training, false in time can be more understanding, flexible use.

8. Additional benefits: Vim is very useful and convenient, some prior contact but not much knowledge, in the course of learning Linux due to the needs of the curriculum, more in-depth study of the relevant methods of operation, a lot of harvest.

   In the learning process, due to personal note habits, Linux and Vim learning specific notes are recorded in the notebook, no electronic, not in detail in this blog. This blog more is I after the completion of the course of the summary and reflection, I hope in the future with a summary of the experience and solve the temporary doubts of the goal, to carry out more in-depth study.
