       <<[-]word     The  shell input is read up to a line that is the same as
		     word after any quoting has been removed, or to an end-of-
		     file.  No	parameter  substitution, command substitution,
		     arithmetic substitution or file name generation  is  per-
		     formed  on  word.	The resulting document, called a here-
		     document, becomes the standard input. If any character of
		     word is quoted, then no interpretation is placed upon the
		     characters of the document. Otherwise,  parameter	expan-
		     sion,  command  substitution, and arithmetic substitution
		     occur, \NEWLINE is ignored, and \ must be used  to  quote
		     the  characters \, $, `.
