抜粋
The letters `acdeijstuACDST' select the new attributes for the files:
append only (a), compressed (c), no dump (d), extent format (e),
immutable (i), data journalling (j), secure deletion (s), no
tail-merging (t), undeletable (u), no atime updates (A), no copy on
write (C), synchronous directory updates (D), synchronous updates (S),
and top of directory hierarchy (T).
The following attributes are read-only, and may be listed by lsattr(1)
but not modified by chattr: huge file (h), compression error (E),
indexed directory (I), compression raw access (X), and compressed dirty
file (Z).
同じmanページのさらに下のタグの説明を見てください:
The 'e' attribute indicates that the file is using extents for mapping
the blocks on disk. It may not be removed using chattr(1).
The 'I' attribute is used by the htree code to indicate that a directory
is being indexed using hashed trees. It may not be set or reset using
chattr(1), although it can be displayed by lsattr(1).
