Need to use dd to generate a large file from a sample file of random data. This is because I don't have /dev/urandom.
I create a named pipe then:
dd if=mynamed.fifo do=myfile.fifo bs=1024 count=1024
but when I cat a file to the fifo that's 1024 random bytes:

deroff
deroff(1) User Commands deroff(1)NAME
deroff - remove nroff/troff, tbl, and eqn constructs
SYNOPSIS
deroff [ -m [m | s | l] ] [-w] [-i] [ filename...]
DESCRIPTION
deroff reads each of the filenames in sequence and removes all troff(1) requests, macro calls, backslash constructs, eqn(1) constructs
(between .EQ and .EN lines, and between delimiters), and tbl(1) descriptions, perhaps replacing them with white space (blanks and blank
lines), and writes the remainder of the file on the standard output. deroff follows chains of included files (.so and .nx troff commands);
if a file has already been included, a .so naming that file is ignored and a .nx naming that file terminates execution. If no input file is
given, deroff reads the standard input.
OPTIONS -m The -m option may be followed by an m, s, or l. The -mm option causes the macros to be interpreted so that only running text is
output (that is, no text from macro lines.) The -ml option forces the -mm option and also causes deletion of lists associated
with the mm macros.
-w If the -w option is given, the output is a word list, one ``word'' per line, with all other characters deleted. Otherwise, the
output follows the original, with the deletions mentioned above. In text, a ``word'' is any string that contains at least two let-
ters and is composed of letters, digits, ampersands (&), and apostrophes ('); in a macro call, however, a ``word'' is a string
that begins with at least two letters and contains a total of at least three letters. Delimiters are any characters other than
letters, digits, apostrophes, and ampersands. Trailing apostrophes and ampersands are removed from ``words.''
-i The -i option causes deroff to ignore .so and .nx commands.

deroff is not a complete troff interpreter, so it can be confused by subtle constructs. Most such errors result in too much rather than too
little output.
The -ml option does not handle nested lists correctly.
