The linux usr src directory is under the "/usr/src" directory. You can check whether the directory exists through the "ls /usr/src" command. If the directory exists, the files and subdirectories in it will be listed. If If it does not exist, it will prompt "No such file or directory".
The operating system of this tutorial: Linux5.18.14 system, Dell G3 computer.
In most Linux systems, the `/usr/src` directory is usually used to store source code files. You can check whether the directory exists with the following command:
``` ls /usr/src ```
If the directory exists, the files and subdirectories in it will be listed. If it does not exist, it will prompt "No such file or directory".
Please note that some Linux distributions may use other directories to store source code files. For some distributions, you can also use a package manager to get the source code files without having to download and save them manually.
