DESCRIPTION

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

NOTES

79       This  compression/decompression utility works only with files stored in
80       a UFS file system.
81
82
83       There is no obvious way to determine  whether  a  given  file  is  com‐
84       pressed,  other  than copying the file and comparing the number of disk
85       blocks of the copy against the original.
