When you type in a command to your shell, it uses a particular variable to ascertain where to look for that command. What is it, and what happens if it's set to NULL?
What will be an ideal response?
The variable in question is PATH and if your PATH is set to NULL (or empty) then the shell won't be able to find any commands at all and will only be able to work with its own built-in commands like echo and exit.
