What do you think would happen if you invoked the following command on the shell? Why?

cat infile | sort | wc -l > infile


It would seem that you've created an infinite loop, where the commands output would be read as its input too, but with the way Unix and Linux shells work, this works fine, with the original contents of infile being sorted and counted, then overwritten by the result of the command.
