====e2fsck====
~**e2fsck** is used to check the ext2/ext3/ext4 family of file systems.
~Note: that in general it is not safe to run e2fsck on mounted filesystems.

==Usage==
~%%Usage: e2fsck [-panyrcdfvtDFV] [-b superblock] [-B blocksize]
[-I inode_buffer_blocks] [-P process_inode_size]
[-l|-L bad_blocks_file] [-C fd] [-j external_journal]
[-E extended-options] device

Emergency help:
-p Automatic repair (no questions)
-n Make no changes to the filesystem
-y Assume "yes" to all questions
