Is there any output from sleep? Where does cat get its input from? What has to happen before the shell will display a prompt?
Enter the following command:
$ sleep 30 | cat /etc/services
There is no output from sleep (try giving the command sleep 30 by itself).
The /etc/services file provides input for cat (when cat has an argument, it
does not check standard input). The sleep command has to run to comple-
tion before the shell will display a prompt.
