Introduction to UNIX Systems

First, the basic knowledge

1. Operating system

   The interface between user and computer hardware is to control and manage various hardware and software resources in the computer. It is a multi-user, multi-tasking, time-sharing operating system.

   For CTSS: If a process requires 16 time slices, it is now assigned only 10 according to priority and is ready to go.

2. Development

   1) Interactive time-sharing OS with multi-channel program capability

   2) Unix Birth

   3) Free spread

   4) Production of UNIX commercial edition

   5) UI and OSF two major camps and UNIX standardization

   6) Variants and development of UNIX

   7) The birth and rise of Linux

   PC virtual out of the system Solaris. SUN OS, AIX, etc. are variants.

3. Advantages and disadvantages of UNIX systems

   Advantages: The system is stable, reliable and safe. Multi-user, multi-tasking, time-sharing and so on.

   Disadvantages: Large system, slow installation, poor real-time function, operability and poor maintenance.

4. UNIX System Architecture

   User, Application layer (user's action), Shell layer (translator), Kernel layer (driver, commander), Hardware (performer)

5. UNIX Shell

   The shell is also a high-level programming language with variables and statements. The. exe program is actually running. That is, a process. He is an imperative interpreter of language.

6. Introduction to the Solaris system

   The Sun operating system was originally Sun OS and later became Solaris with System V. Now SunOS refers to the Solaris kernel. Support various system architectures: x86, x64 and so on. Its desktop development for Java XXXX. Much like the Windows interface.

   Free software: advocated by the gun organization, satisfies the GPL (Free software General License agreement), LGPL the relatively loose license agreement, allows to publish part of the source code.

   Its filesystem is the UFS UNIX file system. Zfs.

   Version: Solaris10.

   Everything is a file representation. We can go through the configuration file to modify it.

Second, Solaris installation

Third, the basic operation

VI Editor Basic operation

2. Basic operations in the command mode

   Move the cursor, find the string, and delete the copied and pasted content. It is important to note that new content cannot be modified and added in this mode.

4. Basic operations in input mode

   It is mainly used for inputting content, modifying text files or adding new content.

6. Basic operations in the last-line mode

   You can set the VI editor environment, save the file and exit and replace the contents of the file.

   Switching between modes

   aio– "Command mode to input mode

   esc-"input mode to command mode

   :--"command mode to last line mode

   Command mode

   Move cursor: JKHL up or down

   Paging: page Down/up Ctrl f/b

   Line: $ line End 0 beginning

   Between rows: G file end 1G file header

   Merge: J #J merge several rows

   Display line number: Set Nu/nonu

   Delete: x single character dd #dd d$ d^

   Copy: yy #yy

   Paste: p/p

   File lookup:/words or? words position n (undo one operation)/n (undo all operations on the row)

   Last-line mode

   Save file:: wq! Save and Force exit

   : W + file location means Save As

   : q! Do not save, force quit

   To replace the contents of a file:

   : S/old/new only one: s/old/new/g for another line

   : 3,4s/old/new 3-4 Lines

   :%s/old/new/g to replace the entire file (must be written in strict accordance with the rules)

   U user h hostname PWD Path $ users Rights

   Bash Shell, we can use source to make the file valid

   We can modify the command prompt by changing the/etc/profile

   Modify Ip:ifconfig by changing the name of the Hostname.elooogo NIC, one file per Nic
