Question

tee is an internal command.

(a) True

(b) False

The question was posed to me in an internship interview.

The above asked question is from Redirection and Pipes topic in section The Shell of Unix

Answer 1

The correct answer is (b) False

For explanation: tee is an external command and not a feature of the shell. tee command handles a character stream by duplicating its input. It saves one copy in a file and writes the other to standard output.
