SYSTEM UTILITY (“FILE SYSTEM CONSISTENCY CHECK”) FOR CHECKING THE CONSISTENCY OF A FILE SYSTEM IN UNIX-LIKE OPERATING SYSTEMS (E.G. LINUX, MACOS, FREEBSD)
1. <operating system> file system check. The Unix program
that checks a file system for internal consistency and bad
blocks etc. and can repair some faults.
fsck is often used after a crash when the file system has
been left in an inconsistent state, e.g. due to incomplete
flushing of buffers.
