Synchronize data on disk with memory
Syntax
sync
Writes any data buffered in memory out to disk. This can include
(but is not limited to) modified superblocks, modified inodes, and delayed reads
and writes.
This must be implemented by the kernel; The `sync? program does nothing but
exercise the `sync? system call. The kernel keeps data in memory to avoid doing
(relatively slow) disk reads and writes. This improves performance, but if the
computer crashes, data may be lost or the filesystem corrupted as a result.
`sync? ensures everything in memory is written to disk.
Any arguments are ignored, except for a lone `--help? or `--version?
