отладчик файловой системы ext2 / ext3 / ext4 (ext2/ext3/ext4 file system debugger)
SPECIFYING FILES
Many debugfs commands take a filespec as an argument to specify
an inode (as opposed to a pathname) in the file system which is
currently opened by debugfs. The filespec argument may be
specified in two forms. The first form is an inode number
surrounded by angle brackets, e.g., <2>. The second form is a
pathname; if the pathname is prefixed by a forward slash ('/'),
then it is interpreted relative to the root of the file system
which is currently opened by debugfs. If not, the pathname is
interpreted relative to the current working directory as
maintained by debugfs. This may be modified by using the debugfs
command cd.
