Linux directory Structure

In the Linux system, there are several directories are more important, usually need to be careful not to accidentally delete or arbitrarily change the internal files.

/etc: Also mentioned above, this is the configuration file in the system, if you change a file in this directory may cause the system will not start.

/bin,/sbin,/usr/bin,/usr/sbin: This is the placement directory of the system preset execution files, such as LS is in the/bin/ls directory.

It is worth noting that,/bin,/usr/bin is the instruction for the system user (except for root), and/sbin,/usr/sbin is the command to use for root.

/var: this is a very important directory, the system ran a lot of programs, then each program will have a corresponding log generated, and these logs are recorded in this directory, specifically in the/var/log directory, the other mail preset placement is also here.

• Absolute path:
  The path is written by the root directory/write, for example:/usr/share/doc this directory.
• Relative path:
  The way the path is written, not by/writing, for example, by/usr/share/doc to the bottom of/usr/share/man, can be written as: CD. /man This is how the relative path is written!

•     ls: List directory    CD: Switch directory    pwd: Show current directory    mkdir: Create a new directory    rmdir: Delete an empty directory    CP: Copy file or directory    RM: Remove file or directory

  Linux file Content View

Use the following command in a Linux system to view the contents of a file: Cat  starts displaying the file contents from the first line  the TAC starts with the last line and can see that the TAC is backwards written by cat! NL   Display, the output line number! More page by page The content of the file is less similar to more, but better than more, he can page forward! Head only looks at a few lines tail only look at the tail a few lines
