Linux basic environment |
|
| Purpose |
1. Familiar with the basic operations under Linux, learn to use various shell commands to operate Linux, and have a perceptual understanding of Linux. 2. Learn to use the vi editor to edit simple C language programs, and be able to compile and debug them. |

The root of the new virtual machine cannot log in without setting a password. You need sudo passwd root to set a password for root before you can log in. Ubuntu uses root to log in for the first time - Programmer Sought In addition, tools cannot be installed directly. The option to install VMware Tools in VMware is grayed out and cannot be installed_Rhyme_7's Blog-CSDN Blog |

Select the appropriate basic common command, perform the following operations and record the results |
|||
| Experiment code, experiment process (snapshot in interface mode), experiment result (snapshot) |
1) Run the pwd command to determine your current working directory; 2) Display the contents of the current working directory; 3) Use long format to display all files;
4) List the details of all directories and files under the /bin directory, sorted by modification time;
5) Use the mkdir command to create a subdirectory subdir 6) Change the working directory to the root directory (/).
