a question on input redirection

[mark at umcp-cs.UUCP]

	My major concern with the use of
	'cat' is the very real possibility of leaving the cat process
	running if the program terminates on it's own (that is, not due
	to an end of file from the termination of cat).  This can result
	in strange occurrences where some of your input is taken by the
	cat process and shipped to nowhere while the rest is taken by the
	shell.

Not so.  When the program terminates the 'cat' gets a SIGPIPE
signal which kills it off.
