NAME
     fiocompress - file compression utility

SYNOPSIS
     /sbin/fiocompress -c [-m] [-b blocksize] inputfile outputfile


     /sbin/fiocompress -d inputfile outputfile


DESCRIPTION
     The fiocompress utility is  a  file  compression  tool  that
     works  together  with  the  dcfs(7FS) file system to perform
     per-file compression. You can use fiocompress to  decompress
     a  compressed  file or mark a compressed file as compressed,
     causing automatic decompression on read. The primary use  of
     fiocompress is to compress files in the boot archive.


     Note that this utility is not  a  Committed  interface.  See
     attributes(5).

OPTIONS
     The following options are supported:

     -b blocksize

         Specify a block size for compression. The default  block
         size is 8192.


     -c

         Compress the specified file.


     -d

         Decompress the specified file.


     -m

         Mark the compressed file for automatic decompression  on
         read. Can be used only in conjunction with -c.

NOTES
     This compression/decompression utility works only with files
     stored in a UFS file system.


     There is no obvious way to determine whether a given file is
     compressed,  other  than  copying the file and comparing the
     number of disk blocks of the copy against the original.
