Which command in Linux will show the directory contents?

The command that displays the contents of a directory in Linux is 'ls'. This command lists all files and folders within the current directory by default. It can also be used with various options to modify the output, such as showing hidden files or providing more detailed information about the files (like file size and permissions).

The other commands serve different purposes: 'pwd' is used to print the current working directory, showing the path you are currently in. 'cd' changes the current directory to a specified one, and 'mv' is used for moving or renaming files and directories. Thus, 'ls' is the correct command for viewing directory contents.
