DIR(5) - File Formats Manual # DIR(5) - File Formats Manual
NAME # dir, dirent - directory file format
SYNOPSIS # #include <dirent.h>
DESCRIPTION # Directories provide a convenient hierarchical method of grouping files while obscuring the underlying details of the storage medium. A directory file is differentiated from a plain file by a flag in its inode(5) entry. It consists of records (directory entries) each of which contains information about a file and a pointer to the file itself.

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).

FS(5) - File Formats Manual # FS(5) - File Formats Manual
NAME # fs, inode - format of file system volume
SYNOPSIS # #include <sys/types.h>
#include <ufs/ffs/fs.h>
#include <ufs/ufs/inode.h>
DESCRIPTION # The files <ufs/ffs/fs.h> and <ufs/ufs/inode.h> declare several structures and define variables and macros which are used to create and manage the underlying format of file system objects on random access devices (disks).
The block size and number of blocks which comprise a file system are parameters of the file system.

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.

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.

NAME # newfs_ext2fs - construct a new ext2 file system
SYNOPSIS # newfs_ext2fs [-FINqZ] [-b block-size] [-D inodesize] [-f frag-size] [-i bytes-per-inode] [-m free-space] [-n inodes] [-O filesystem-format] [-S sector-size] [-s size] [-V verbose] [-v volname] special
DESCRIPTION # newfs_ext2fs is used to initialize and clear ext2 file systems before first use. Before running newfs_ext2fs, the disk must be labeled using disklabel(8).
