Syntax and Options for the fsck Command

The fsck command checks and repairs inconsistencies in file systems. If you run the fsck command without any options, it interactively asks for confirmation before making repairs. This command has four options.

Command and Option 


fsck -m

Checks whether a file system can be mounted 

fsck -y

Assumes a yes response for all repairs 

fsck -n

Assumes a no response for all repairs 

fsck -o p

Noninteractively preens the file system, fixing all expected (innocuous) inconsistencies, but exits when a serious problem is encountered
