50 + If a space is specified as the terminator, then fields are separated by

52   Different terminators may be given for different fields by specifying
53   additional
54   .I \-t
55   options between each output specification.

67 + The same output file may not appear more than once.
68   Commands are given in quotes, and begin with an exclamantion point ('!').
69 + At most, one command may reliably write to its standard output, and
70 + doing so is incompatible with

73 + A hyphen ('-') by itself tells
74 + .I rsplit
75 + to write directly to its standard output, and may appear multiple times.
76 + The options before the first appearance determine the
77 + standard output header parameters.
78 + A period ('.') tells
79 + .I rsplit
80 + to discard the corresponding data, and also may appear multiple times.

112   If a

104 A hyphen ('-') by itself can be used to indicate the standard

106 Results will be unpredictable if the standard output is specified
