This article mainly explains "what are the commonly used software in Linux system". Interested friends may wish to have a look. The method introduced in this paper is simple, fast and practical. Next, let the editor take you to learn "what are the commonly used software in the Linux system?"

Open the installed Linux system (ubuntu18.04) 1. The installation editor uses the statement: sudo apt-get install vim installs vim, and you can check to see if the vim editor is installed before installation. (special note: it is best to update the software before installing vim, use the instruction sudo apt-get update.) the reason for adding sudo is that they need to use administrator privileges to install and update the software. two。 Installing the gcc compiler is similar to installing vim using sudo apt-get install gcc. After installation, you can use cc-v to view compiler version information, and so on. The cc-v interface is as follows:

(gcc is often abbreviated as cc) of course, it is best to use the command to update the software before installing all the software. 3. Before creating a folder and entering the file to create a folder, you can use the instruction ls to see what files are on the system. Then create a file with the mkdir+ file name and see if the file has been created. (if you create a file named workspace mkdir workspace) enter the file and use the command cd workspace. Then enter the directory. Then create a file named les1 (mkdir les1). Enter the les1 file (cd les1). Create a .c file: touch a.c. 4. Edit the file and enter vi a.c to enter the interface

You will find that the user cannot enter information from the keyboard, so we need to press an I from the keyboard to display INSERT (for insertion) below.

You can then use the keyboard to enter the code. After the input is completed, you can press Esc to exit the insert operation. Then press shift and colon at the same time to enter wq from the keyboard (for save and exit).

5. Compile the file input instruction: cc a.c (cc is the abbreviation of gcc) if no error is reported, enter ls from the keyboard to see if an executable file a.out file has been generated.

6. Permission to view the file (optional or not) use the instruction ls-lr to indicate readable w, write x, execute

7. Execute the file using the instruction. / a.out to execute the program. Output hello world!

At this point, I believe that everyone on the "Linux system commonly used software which have a deeper understanding, might as well come to the actual operation of it!" Here is the website, more related content can enter the relevant channels to inquire, follow us, continue to learn!
