Which command can be used to display the current working directory?

The command used to display the current working directory is "pwd", which stands for "print working directory." When executed, this command prints the full path of the directory the user is currently in, allowing them to easily identify their location within the filesystem.

The "cd" command is used to change the current directory but does not provide information about where the user currently is. The "ls" command lists the contents of the current directory rather than indicating the directory itself. Lastly, "whereis" is used to locate the binary, source, and manual page files for a command, but it does not reveal any information about the current directory. Thus, pwd is the appropriate command for this requirement.
