       shrinkfile - shrink a file on a line boundary

       shrinkfile [ -n ] [ -m maxsize ] [ -s size ] [ -v ] file...

       The shrinkfile program shrinks files to a given size if the size is larger than maxsize,
	preserving  the data at the end of the file.  Truncation is performed on line boundaries,
       where a line is a series of bytes ending with a newline, \n.   There  is  no  line  length
       restriction and files may contain any binary data.

       Temporary  files are created in the <pathtmp in inn.conf> directory.  The ``TMPDIR'' envi-
       ronment variable may be used to specify a different directory.

       A newline will be added to any non-empty file that does not end with a newline.	The maxi-
       mum file size will not be exceeded by this addition.

       -s     By  default,  size  is assume to be zero and files are truncated to zero bytes.  By
	      default, maxsize is the same as size.  If maxsize is less  than  size,  maxsize  is
	      reset to size.  The ``-s'' flag may be used to change the truncation size.  Because
	      the program truncates only on line boundaries, the final size may be  smaller  then
	      the  specified  truncation  size.   The  size  and maxsize parameter may end with a
	      ``k'', ``m'', or ``g'', indicating kilobyte (1024), megabyte (1048576) or  gigabyte
	      (1073741824)  lengths.   Uppercase letters are also allowed.  The maximum file size
	      is 2147483647 bytes.

       -v     If the ``-v'' flag is used, then shrinkfile will print a status line if a file  was

       -n     If  the ``-n'' flag is used, then shrinkfile will exit 0 if any file is larger than
	      maxsize and exit 1 otherwise.  No files will be altered.

       Example usage:

	      shrinkfile -s 4m curds
	      shrinkfile -s 1g -v whey
	      shrinkfile -s 500k -m 4m -v curds whey
	      if shrinkfile -n -s 100m whey; then echo whey is way too big; fi
