Log in to the Linux system and create a new terminal

Use thetouch command in the terminalCreate a file

Use Vim editor, write some content in the file, enter: wq to save and exit

Return to the terminal,Use ls -l to view file permissions

Use thechmod command and the x parameter to give the file executable permissions

The x here represents executable permissions (read, write, and executable permissions are represented by r, w, and x respectively); and the a represents all, which is the three identities of user, user group, and other users. All permission values are modified (if you only modify one of the three identities of user permissions (user), user group permissions (group), and other users (others), you can use u, g or o to replace the letter a); x The plus sign in front means adding permissions (if a permission is to be removed, it will be a minus sign in English).
