The E2fsprogs package contains the utilities for handling the
file system. It also supports the
journaling file system.
Contains routines for device identification and token extraction
The common error display routine
Used by dumpe2fs, chattr, and lsattr
Contains routines to enable user-level programs to manipulate an ext2 file system
Used by debugfs
Contains routines for generating unique identifiers for objects that may be accessible beyond the local system
UUID means Universally Unique IDentifier,which standardized by the Open Software Foundation (OSF) as part of the Distributed Computing Environment (DCE). It consists of 32 hexadecimal digits, displayed in 5 groups separated by hyphens, for a total of 36 characters.
uuidgen can creates new UUIDs. Each new UUID can reasonably be considered unique among all UUIDs created, on the local system and on other systems, in the past and in the future
A daemon used by the UUID library to generate time-based UUIDs in a secure and guranteed-unique fashion.
An error table compiler; it converts a table of error-code names and messages into a C source file suitable for use with the com_err library
Saves the output of a command in a log file
Converts a table of command names and help messages into a C source file suitable for use with the libss subsystem library
Finds a file system by label or Universally Unique Identifier (UUID)
A file system debugger; it can be used to examine and change the state of an ext2 file system
Creates an ext2 or ext3 file system on the given device
Displays or changes the file system label on the ext2 file system present on a given device
Lists the attributes of files on a second extended file system
Prints the super block and blocks group information for the file system present on a given device
A command line utility to locate and print block device attributes
Changes the attributes of files on an ext2 file system; it also changes ext3 file systems, the journaling version of ext2 file systems
Adjusts tunable file system parameters on an ext2 file system
Can be used to enlarge or shrink an ext2 file system
Searches a device (usually a disk partition) for bad blocks
Reports on how badly fragmented a particular file might be
Is used to check, and optionally repair, file systems
Is used to check, and optionally repair ext2 file systems and ext3 file systems
Replays the undo log undo_log for an ext2/ext3/ext4 filesystem found on a device. This can be used to undo a failed operation by an e2fsprogs program.
Is used to save critical ext2 file system data to a file
Used to create a lost+found directory on an ext2 file system; it pre-allocates disk blocks to this directory to lighten the task of e2fsck
