e2fsprogs (sometimes called the e2fs programs) is a set of utilities for maintaining the ext2 and ext3 file systems. Since those file systems are often the default for Linux distributions, it is commonly considered to be essential software. Software maintenance is one of the activities in software engineering, and is the process of enhancing and optimizing deployed software (software release), as well as remedying defects. ...

Included with e2fsprogs are:

  • e2fsck, a fsck program that checks for and corrects inconsistencies
  • mke2fs, used for creating ext2 and ext3 file systems
  • tune2fs, used to modify file system parameters
  • dumpe2fs, which prints file system information
  • debugfs, used to manually view or modify internal structures of the file system

Many of these utilties are based on the libext2fs library. The system utility fsck (for file system check or file system consistency check) is a tool for checking the consistency of a file system in the Unix system and clones thereof. ...


Despite what its name might suggest, the e2fsprogs work not only with ext2, but also with ext3, which is based on ext2. Although ext3's journaling capability can reduce the need to use e2fsck, it is sometimes still necessary. A journaling file system is a file system that logs changes to a journal (usually a circular log in a specially-allocated area) before actually writing them to the main file system. ...


As the userspace companion for the the ext2 and ext3 drivers in the Linux kernel, the e2fsprogs are most commonly used with the Linux operating system. However, they have been ported to other systems, such as FreeBSD and Darwin. An operating system usually segregates the available system memory into kernel space and user space. ...
