How can you display the contents of a directory in Linux?

• A. ls
• B. dir
• C. show
• D. list

Answer: (A)

In Linux, the command used to display the contents of a directory is "ls." This command provides a straightforward way to list files and directories in the current working directory or a specified directory. By default, "ls" outputs the names of the files and subdirectories, and it can be modified using various options to include more information, such as file sizes, permissions, and modification dates. For instance, using "ls -l" will give a more detailed listing that includes file permissions, number of links, owner, group, size, and the last modified date and time. Similarly, "ls -a" will include hidden files (those starting with a dot), which are typically not shown in standard outputs. The other options refer to commands that are either not standard in Linux or do not exist in the context of displaying directory contents. "dir" is more commonly associated with MS-DOS and may not provide the same functionality in all Linux distributions, while "show" and "list" do not correspond to any standard Linux command for this purpose. Hence, "ls" is recognized as the primary and most widely used command for this function in the Linux environment.
