e2fsck is used to check a Linux second extended file system (ext2fs). E2fsck also
supports ext2 filesystems containing a journal, which are also sometimes known as ext3
filesystems, by first applying the journal to the filesystem before continuing with

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).

Note that in general it is not safe to run e2fsck on mounted filesystems. The only

The exit code returned by e2fsck is the sum of the following conditions:
0 - No errors
1 - File system errors corrected
2 - File system errors corrected, system should
be rebooted
4 - File system errors left uncorrected
8 - Operational error
16 - Usage or syntax error
32 - E2fsck canceled by user request
128 - Shared library error
