# Line 46 | Line 56 | The second form of
56   with a hyphen simply removes the header
57   and copies the body of the file from the standard
58   input to the standard output.
59 + If the
60 + .I \-d
61 + option is included, then the resolution string will be elided as well.
62   .PP
63   The third form of
64 + .I "getinfo \-a"
65 + adds one or more header lines to the standard input.
66 + These lines are given as arguments to
67 + .I getinfo,
68 + and must be quoted if they contain spaces.
69 + .PP
70 + The fourth form of
71   .I "getinfo \-c"
72   is followed by a command and its arguments, which is executed
73   on the data segment of the standard input.
# Line 57 | Line 77 | This is roughly equivalent to the following sequence,
77   require the input to be in a file:
78   .IP "" .2i
79   ( getinfo < input ; getinfo - < input | command .. )
80 + .PP
81 + If the
82 + .I \-d
83 + option is included, then the resolution string will be copied
84 + before the command is called.
