What command would you use to list all files and directories in the current directory?

• A. ls -l
• B. list
• C. dir
• D. show

Answer: (A)

The command used to list all files and directories in the current directory is the "ls" command, which stands for "list." The option "-l" is particularly useful as it provides a long listing format, displaying not only the names of the files and directories but also additional information such as permissions, number of links, owner, group, size, and modification date. This additional detail can be very helpful for users who need to understand more about the files in their current working directory. In contrast, the command "list" does not exist in standard Linux command-line operations; it is not recognized as a valid command. "dir" is a command that is used in some operating systems, including Windows, to list directory contents, but its use in Linux is less common and not standard. Lastly, "show" is not a command used for listing files and directories in Linux, making it an incorrect choice as well. The "ls -l" command is therefore the correct and most commonly used method to achieve this task in a Linux environment.
