SYNC (II)                    6/12/72                    SYNC (II)

NAME            sync -- update super-block

SYNOPSIS        sys sync  / sync = 36.; not in assembler

DESCRIPTION     sync causes the super block for all file systems

                to be written out.  It is only necessary on sys-

                tems in which this writing may be delayed for a

                long time, i.e., those which incorporate hardware

                protection facilities.

                It should be used by programs which examine a

                file system, for example check, df, tm, etc.
