 !!!Signal: Terminal Input on Background Process 
 The process is trying to read from a terminal that it no longer is the controlling terminal for. This process will be stopped until a [SIGCONT] is sent. This signal can be caught and ignored, see [SIGTSTP], [SIGSTOP] and [SIGCONT] 
+An example is:  
+ bash$ cat > /dev/null &  
+ [[1] 31731  
+ [[1] + suspended (tty input) cat  
+By default, cat will read from standard input, but the & character means that this command is run in the background, and the terminal's input goes back to the shell. When cat tries to read from the terminal's stdin, a SIGTTIN signal is raised.
