Pipetest

clitest and stdin don't always work well together. StackOverflow wasn't much help (shocked pikachu)! Buried deep in the interwebs is the bash advice to check for a TTY and whether stdin was piped with this: if [ ! -t 0 ] && [ -p /dev/stdin ];. Using this, I wanted to see how to do something similar in Python to make clitest work. Even deeper on the internet was this gem, which led me to the answer - use stat in Python to test whether stdin is a FIFO (pipe).

Thus, the answer to this hours long search is simply this function:
