fsckShort for file system check, fsck is a system utility that is used to check and repair inconsistencies in Unix and Unix-based file systems, including Linux. Fsck can be run in one of two modes:
- Interactive mode is where fsck scans the file system and, at each error, prompts the user to correct or continue without making changes to the file system.
- Noninteractive mode allows fsck to run and repair all problems it finds automatically without user input.
On a Windows-based system, the equivalent utility is called chkdsk.
