BADSECT(8) - System Manager’s Manual # BADSECT(8) - System Manager’s Manual
NAME # badsect - create files to contain bad sectors
SYNOPSIS # badsect bbdir sector …
DESCRIPTION # badsect makes a file to contain a bad sector. Normally, bad sectors are made inaccessible by the standard formatter, which provides a forwarding table for bad sectors to the driver. If a driver supports the bad blocking standard, it is much more preferable to use that method to isolate bad blocks, since the bad block forwarding makes the pack appear perfect, and such packs can then be copied with dd(1).

CLRI(8) - System Manager’s Manual # CLRI(8) - System Manager’s Manual
NAME # clri - clear inodes
SYNOPSIS # clri special_device inode_number …
DESCRIPTION # clri is obsoleted for normal file system repair work by fsck(8).
clri zeros out the inodes with the specified inode numbers on the filesystem residing on the given special_device. The fsck(8) utility is usually run after clri to reclaim the zero’ed inodes and the blocks previously claimed by those inodes.

Daily DAILY(8) - System Manager’s Manual # DAILY(8) - System Manager’s Manual
NAME # daily, weekly, monthly - periodic system maintenance
DESCRIPTION # The three files /etc/daily, /etc/weekly, and /etc/monthly are shell scripts run on a periodic basis by the clock daemon, cron(8). They take care of some basic administrative tasks. Their output, if any, is mailed to root.
Note: The scripts are all run as part of root’s crontab(5). However, it is strongly suggested that the root mail account be an alias that forwards messages to a real user or set of users.

DUMPFS(8) - System Manager’s Manual # DUMPFS(8) - System Manager’s Manual
NAME # dumpfs - dump file system information
SYNOPSIS # dumpfs [-m] filesys | device
DESCRIPTION # dumpfs prints out the super block and cylinder group information for the file system or special device specified, unless -m is specified. The listing is very long and detailed.
dumpfs is useful mostly for finding out certain file system information such as the file system block size, minimum free space percentage, and the file system level that can be upgraded with the -c option of fsck_ffs(8).

FSCK_EXT2FS(8) - System Manager’s Manual # FSCK_EXT2FS(8) - System Manager’s Manual
NAME # fsck_ext2fs - Second Extended File System consistency check and interactive repair
SYNOPSIS # fsck_ext2fs [-dfnpy] [-b block#] [-m mode] filesystem
DESCRIPTION # fsck_ext2fs performs interactive file system consistency checks and repairs the filesystem specified. It is normally invoked from fsck(8).
The kernel takes care that only a restricted class of innocuous file system inconsistencies can happen unless hardware or software failures intervene.

NAME # fsck_ffs - Fast File System consistency check and interactive repair
SYNOPSIS # fsck_ffs [-fnpy] [-b block#] [-c level] [-m mode] filesystem
DESCRIPTION # fsck_ffs performs interactive file system consistency checks and repairs the file system specified. It is normally invoked from fsck(8).
The kernel takes care that only a restricted class of innocuous file system inconsistencies can happen unless hardware or software failures intervene.

FSCK_MSDOS(8) - System Manager’s Manual # FSCK_MSDOS(8) - System Manager’s Manual
NAME # fsck_msdos - DOS/Windows (FAT) file system consistency checker
SYNOPSIS # fsck_msdos [-fnpy] filesystem
DESCRIPTION # The fsck_msdos utility verifies and repairs FAT file systems (more commonly known as DOS file systems). It checks the specified filesystem and tries to repair all detected inconsistencies, requesting confirmation before making any changes.
If the -p flag is given, fsck_msdos preens the specified filesystem.

Fsck FSCK(8) - System Manager’s Manual # FSCK(8) - System Manager’s Manual
NAME # fsck - file system consistency check and interactive repair
SYNOPSIS # fsck [-dfNnpvy] [-b block#] [-l maxparallel] [-T fstype:fsoptions] [-t fstype] [special | node …]
DESCRIPTION # The fsck command 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.

FSDB(8) - System Manager’s Manual # FSDB(8) - System Manager’s Manual
NAME # fsdb - FFS debugging/editing tool
SYNOPSIS # fsdb [-d] -f fsname
DESCRIPTION # fsdb opens fsname (usually a raw disk partition) and runs a command loop allowing manipulation of the file system’s inode data. You are prompted to enter a command with fsdb (inum X)> where X is the currently selected i-number. The initial selected inode is the root of the file system (i-number 2).

FSIRAND(8) - System Manager’s Manual # FSIRAND(8) - System Manager’s Manual
NAME # fsirand - randomize inode generation numbers
SYNOPSIS # fsirand [-bfp] special …
DESCRIPTION # The fsirand command installs random generation numbers on all the inodes for each filesystem specified on the command line by special. This increases the security of NFS-exported filesystems by making it difficult to “guess” filehandles.
Note: newfs(8) now does the equivalent of fsirand itself so it is no longer necessary to run fsirand by hand on a new filesystem.
