Which command is used to list the contents of the current directory in a Linux terminal?

The command used to list the contents of the current directory in a Linux terminal is 'ls'. This command is a fundamental utility in Linux and Unix-like operating systems, providing users with a straightforward way to view files and directories in their current working directory. When executed without any options or arguments, 'ls' will display the names of all files and subdirectories within the current directory.

While the command 'dir' can also list the directory contents, it is more commonly associated with DOS and Windows command prompts, rather than Linux. The other options, 'list' and 'show', do not correspond to any standard command in Linux for listing directory contents. Thus, 'ls' stands out as the correct and most widely used command for this purpose in the Linux environment.
