A question on input redirection

[mark at umcp-cs.UUCP]

	I have been trying to come up with a generalized
	way to direct input to a command such that it takes
	it's input from a file for a while and then begins
	taking input from the standard input (keyboard).

If your command is 'cmd', why not:
	cat file1 file2 ... filen - | cmd
