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
