Common linux commands,

In linux systems, commands must be frequently used, and some commands may not be remembered, so it is very troublesome to search for them on the Internet. So here I will record the commonly used commands, and I will add new commands in the future.

1. cd command

1 cd document/test # enter 2 cd .. # Under the document/test directory based on the current directory to return 3 cd ~ # Return the root directory

 

2. ls command

 

-L: Lists long data strings, including object attributes and permission data.-a: lists all objects, together with hidden objects (beginning. -d: only list the directory itself, rather than list the file data of the directory-h: The file capacity is more readable (GB, kB, etc) column-R: It is listed together with the sub-directory content (recursively listed). It means that all files in the directory will be displayed.
