fsck

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.

Used on Usenet newsgroup alt.sysadmin.recovery as

substitute for "fuck" and became more main-stream after the

Communications Decency Act.
