Package e2fsprogs

Utilities for managing ext2, ext3, and ext4 filesystems

The e2fsprogs package contains a number of utilities for creating,
checking, modifying, and correcting any inconsistencies in second,
third and fourth extended (ext2/ext3/ext4) filesystems. E2fsprogs
contains e2fsck (used to repair filesystem inconsistencies after an
unclean shutdown), mke2fs (used to initialize a partition to contain
an empty ext2 filesystem), debugfs (used to examine the internal
structure of a filesystem, to manually repair a corrupted
filesystem, or to create test cases for e2fsck), tune2fs (used to
modify filesystem parameters), and most of the other core ext2fs
filesystem utilities.

You should install the e2fsprogs package if you need to manage the
performance of an ext2, ext3, or ext4 filesystem.

General Commands (Section 1)
chattr changes the file attributes on a Linux file system. The format of a symbolic mode is +-=[aAcCdDeijsStTu]. The operator '+' causes the selected attributes...
fuse2fs is a FUSE file system client that supports reading and writing from devices or image files containing ext2, ext3, and ext4 file systems.
lsattr lists the file attributes on a second extended file system. See chattr(1) for a description of the attributes and what they mean.
File Formats (Section 5)
e2fsck.conf is the configuration file for e2fsck(8). It controls the default behavior of e2fsck(8) while it is checking ext2, ext3, or ext4 filesystems. The...
The second, third, and fourth extended file systems, or ext2, ext3, and ext4 as they are commonly known, are Linux file systems that have historically been the...
mke2fs.conf is the configuration file for mke2fs(8). It controls the default parameters used by mke2fs(8) when it is creating ext2, ext3, or ext4 filesystems...
System Administration (Section 8)
badblocks is used to search for bad blocks on a device (usually a disk partition). device is the special file corresponding to the device (e.g /dev/hdc1)...
The debugfs program is an interactive file system debugger. It can be used to examine and change the state of an ext2, ext3, or ext4 file system. device is a...
dumpe2fs prints the super block and blocks group information for the filesystem present on device. Note: When used with a mounted filesystem, the printed...
e2freefrag is used to report free space fragmentation on ext2/3/4 file systems. filesys is the filesystem device name (e.g. /dev/hdc1, /dev/md0). The e2freefrag...
e2fsck is used to check the ext2/ext3/ext4 family of file systems. For ext3 and ext4 filesystems that use a journal, if the system has been shut down uncleanly...
The e2image program will save critical ext2, ext3, or ext4 filesystem metadata located on device to a file specified by image-file. The image file may be...
e2label will display or change the filesystem label on the ext2, ext3, or ext4 filesystem located on device. If the optional argument new-label is not present...
e2undo will replay the undo log undo_log for an ext2/ext3/ext4 filesystem found on device. This can be used to undo a failed operation by an e2fsprogs program.
e4crypt performs encryption management for ext4 file systems.
e4defrag reduces fragmentation of extent based file. The file targeted by e4defrag is created on ext4 filesystem made with "-O extent" option (see mke2fs(8))...
filefrag reports on how badly fragmented a particular file might be. It makes allowances for indirect blocks for ext2 and ext3 filesystems, but can be used on...
The logsave program will execute cmd_prog with the specified argument(s), and save a copy of its output to logfile. If the containing directory for logfile does...
mke2fs is used to create an ext2, ext3, or ext4 filesystem, usually in a disk partition (or file) named by device. The file system size is specified by fs-size...
mklost+found is used to create a lost+found directory in the current working directory on a Linux second extended file system. There is normally a lost+found...
The resize2fs program will resize ext2, ext3, or ext4 file systems. It can be used to enlarge or shrink an unmounted file system located on device. If the...
tune2fs allows the system administrator to adjust various tunable filesystem parameters on Linux ext2, ext3, or ext4 filesystems. The current values of these...
