NAME
       crfile - Create arbitrary sized files

SYNOPSIS
       crfile -f filename -s size  [-w[len] | -n]

DESCRIPTION
       crfile is used to create a file of the specified size, filled with ran‐
       dom ASCII characters.  The -n  switch  allows  the  creation  of	 files
       padded with null characters (ie. containing large 'holes') that have an
       apparent length of the specified size,  but  contain  only  one	random
       character.

OPTIONS
       -f filename
	      specifies	 the file to be created.  If the file exists, an error
	      is generated.

       -s size
	      size is the size of the file, in bytes

       -wlen  wrap each line of output at len  characters.   If	 len  omitted,
	      wrap at 80 characters.

       -n     Pad  the file with null characters instead of random ASCII text.
	      This allows for the rapid creation of large  files  (useful  for
	      verifying	 that  programs can deal with files > 2GB in size, for
	      example).
