NAME

       shrinkfile - shrink a file on a line boundary

SYNOPSIS

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

DESCRIPTION

       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''
       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.

OPTIONS

       -s     By default, size is assumed 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.

EXAMPLES

       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
