NAME
e2fsck - check a Linux second extended file system
SYNOPSIS
e2fsck [ -pacnyrdfvstDFSV ] [ -b superblock ] [ -B block
size ] [ -l|-L bad_blocks_file ] [ -C fd ] [ -j external-
journal ] [ -E extended_options ] device
DESCRIPTION
e2fsck is used to check a Linux second extended file sys

tem before continuing with normal e2fsck processing.
After the journal has been applied, a filesystem will nor

e2fsck will normally run the journal and exit, unless its
superblock indicates that further checking is required.
device is the device file where the filesystem is stored
(e.g. /dev/hdc1).
