how can you pipe into an if statement?
You can't; an if statement is not a loop and it doesn't read standard input.

MAN(7) Miscellaneous Information Manual MAN(7)
NAME
man - macros to typeset manual
SYNOPSIS
nroff -man file ...
troff -man file ...
DESCRIPTION
These macros are used to lay out pages of this manual. A skeleton page may be found in the file /usr/man/man0/xx.
Any text argument t may be zero to six words. Quotes may be used to include blanks in a `word'. If text is empty, the special treatment
is applied to the next input line with text to be printed. In this way .I may be used to italicize a whole line, or .SM followed by .B to
make small bold letters.
A prevailing indent distance is remembered between successive indented paragraphs, and is reset to default value upon reaching a non-
indented paragraph. Default units for indents i are ens.
Type font and size are reset to default values before each paragraph, and after processing font and size setting macros.
These strings are predefined by -man:
*R `(Reg)', trademark symbol in troff.
*S Change to default type size.
FILES
/usr/lib/tmac/tmac.an
