C++ Interview Questions and Answers


How can you tell what shell you are running on UNIX system?

You can do the Echo $RANDOM. It will return a undefined variable if you are from
the C-Shell, just a return prompt if you are from the Bourne shell, and a 5 digit
random numbers if you are from the Korn shell. You could also do a ps -l and look
for the shell with the highest PID.
