Most commands on Linux can display information on their usage by running the command with the option -h or --help. This option shows a brief summary of the command syntax, options, arguments, and examples. For example, running ls -h or ls --help will display the usage information for the ls command, which lists files and directories. The -h or --help option is a standard convention for most Linux commands, and it is useful for learning how to use a command or checking its available options. However, some commands may not support this option, or may use a different option to display usage information. In that case, you can use the man command to access the manual page for the command, which provides more detailed information on the command usage, description, options, arguments, examples, and references. For example, running man ls will display the manual page for the ls command. The man command is one of the applications covered in the Linux Essentials certification program from the Linux Professional Institute (LPI). References:

The distribution’s package repository is the preferred source for the installation of new applications in a Linux based operating system. A package repository is a collection of software packages that are maintained by the distribution and can be easily installed, updated, or removed using a package manager. Package repositories offer several advantages, such as:

• They ensure compatibility and stability with the system and other packages.
• They provide security updates and bug fixes for the packages.
• They reduce the risk of malware or corrupted files.
• They simplify the dependency management and configuration of the packages.

The other sources are not preferred because they may not offer these benefits and may cause problems with the system. The vendor’s version management system, the vendor’s website, or a CD-ROM disk may contain packages that are not compatible with the distribution or may conflict with other packages. A retail store may not have the latest or the most suitable packages for the system. References:

A recursive directory listing is a way of displaying the files and folders in a directory and all its sub-directories. The recursive option can be used with various commands, such as ls, find, or dir, to list the files recursively. For example, the command ls -R will list all the files and folders inthe current directory and any sub-directories, showing the hierarchy of the file system123 A recursive directory listing does not include the permissions, ownership, or file system details ofthe files, unless specified by other options. For example, the command ls -lR will list the files recursively and also show the permissions, ownership, size, and modification date of each file1 A recursive directory listing also does not include a preview of the content of each file, unless specified by other options. For example, the command ls -R --file-type will list the files recursively and also show the file type indicator, such as / for directories, * for executable files, @ for symbolic links, etc1 References: 1: ls (Unix) - Wikipedia 2: Recursively List all directories and files - Stack Overflow 3: Why is ls -R called “recursive” listing? - Ask Ubuntu
