NAME
sync - synchronize file systems
SYNOPSIS
DESCRIPTION
executes the system call (see sync(2)). If the system is to be stopped, the command must be called to ensure file system integrity.
flushes all previously unwritten system buffers including modified super blocks, modified inodes, and delayed block I/O out to disk. This
ensures that all file modifications are properly saved before performing a critical operation such as a system shutdown. For additional
protection from power failures or possible system crashes, use to execute automatically at periodic intervals (see syncer(1M)).
