.SH SYNOPSIS

\f4sync\f1

|
|
.SH DESCRIPTION
|
|
\f4sync\fP
|
|
executes the
|
|
\f4sync\fP(2)
|
|
system primitive.
|
|
If the system is to be stopped,
|
|
\f4sync\fP
|
|
must be called to insure
|
|
filesystem integrity.
|
|
It flushes all previously unwritten system buffers out to disk,
|
|
thus assuring that all file modifications up to that point are
|
|
saved.
|
|
See
|
|
\f4sync\fP(2)
|
|
for details.
|
|
.SH NOTE
|
|
If you have done a write to a file on a remote machine
|
|
in a Remote File Sharing environment, you cannot use \f4sync\fP to
|
|
force buffers to be written out to disk on the remote machine.
|
|
\f4sync\fP only writes local buffers to local disks.
