special | node ...]
fsckcommand invokes file-system-specific programs to check the special devices listed in the fstab(5) file or on the command line for consistency. It is normally used in the script rc(8) during automatic reboot. If no file systems are specified,
fsckreads the file fstab(5) to determine which file systems to check and in what order. Only partitions in fstab that are mounted “rw” or “ro” and that have non-zero pass numbers are checked. File systems with pass number 1 (normally just the root file system) are checked one at a time. When pass 1 completes, all remaining file systems are checked, with one process spawned per disk drive. The disk drive containing each file system is inferred from the longest prefix of the device name that ends in a digit; the remaining characters are assumed to be the partition designator. By default, file systems which are already mounted read/write are not checked. The options are as follows:
fsckto use the specified block as the location of the superblock. Block 32 is usually an alternate super block. This option is only valid for filesystems that support backup superblocks (ffs and ext2fs).
fsckis compiled to support it.
fsckexcept for “CONTINUE?”, which is assumed to be affirmative. File systems will not be opened for writing. This is the default for file systems to be checked that are concurrently mounted writable.
fsckwill check all file systems listed in fstab(5) according to their pass number, or any special devices listed on the command line, and will make minor repairs without human intervention. Any major problems will cause
fsckto exit with a non-zero exit code, so as to alert any invoking program or script that human intervention is required.
fsckonly for the comma separated list of file system types. If the list starts with “no”, invoke
fsckonly in the file system types that are not specified in the list.
fsckto assume “yes” as the answer to all operator questions.
-noptions are specified, the user may force
fsckto assume an answer of “yes” to all the remaining questions by replying to a question with a value of “F”.
