The command line that will create or, in case it already exists, overwrite a file called data with the output of ls is ls > data. The > character is a redirection operator that redirects the standard output (STDOUT) of a command to a file. If the file does not exist, it will be created. If the file already exists, it will be overwritten. The 3> character is not a valid redirection operator. The >& character is a redirection operator that redirects both standard output (STDOUT) and standard error (STDERR) of a command to a file. The >> character is a redirection operator that appends the standard output (STDOUT) of a command to a file, without overwriting the existing file contents. References: LPI Exam 101 Detailed Objectives, Topic 103: GNU and Unix Commands, Weight: 25, Objective 103.3: Perform basic file management, Redirection

The modes of the vi editor that are correct are insert mode and command mode. The vi editor is a modal editor, which means that it has different modes for different operations. The insert mode allows the user to insert text into the file. The command mode allows the user to execute commands, such as saving, quitting, moving the cursor, searching, replacing, and so on. The user can switch between the modes by pressing certain keys, such as Esc, i, a, o, and others. The edit mode, change mode, and review mode are not valid modes of the vi editor. References: LPI Exam 101 Detailed Objectives, Topic 103: GNU and Unix Commands, Weight: 25, Objective 103.8: Use vi to create and edit files, vi editor

According to the Filesystem Hierarchy Standard (FHS), the /usr/local/ directory is for use by the system administrator when installing software locally. It needs to be safe from being overwritten when the system software is updated. The /usr/local/bin/ directory is for local binaries that are not managed by the distribution package manager. These binaries should be accessible to all users on the system. Therefore, binaries that have been compiled by the system administrator should be placed in /usr/local/bin/ to follow the FHS. References:
