The correct answer is: C. to list the positional parameters.<\/p>\n

The special shell variable $* is used to list the positional parameters. Positional parameters are the arguments that are passed to a command when it is executed. For example, if you execute the command ls<\/code>, the positional parameters will be ls<\/code> and the list of files in the current directory.<\/p>\n

The other options are incorrect. Option A is incorrect because the exit status of a command is stored in the special shell variable $?. Option B is incorrect because the process number of the current shell is stored in the special shell variable $PPID. Option D is incorrect because the name of the command being executed is stored in the special shell variable $0.<\/p>\n","protected":false},"excerpt":{"rendered":"
