!!!Signal: Pipe This signal is raised when a program writes to a socket or fifo that has no readers. The default action of this signal is to cause the program to terminate. You might see this message if you have a series of commands in a shell pipe line and one of the processes quits. Eg: $ cat somefile | head After "head" has printed out the first 10 lines and quits, "cat" will get a pipe error. However, cat catches the signal and quits gracefully. If you use cvs, then you might see the shell print out a message as cvs doesn't handle this signal gracefully.
