-p FMTFILE or STR (-printFormat)
Print output in the format specified by the given file or string (and ignore other format options).
Tag names in the format file or string begin with a "$" symbol and may contain a leading group name
and/or a trailing "#". Case is not significant. Braces "{}" may be used around the tag name to
separate it from subsequent text. Use $$ to represent a "$" symbol, and $/ for a newline. Multiple
-p options may be used, each contributing a line of text to the output. Lines beginning with
"#[HEAD]" and "#[TAIL]" are output only for the first and last processed files respectively. Lines
beginning with "#[BODY]" and lines not beginning with "#" are output for each processed file. Other
lines beginning with "#" are ignored. For example, this format file:
