       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  /var/spool/news/in.coming/tmp
       directory.  The ``TMPDIR'' environment 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 maximum 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 shrunk.

       -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
