displays the set of extended inode flags associated with the current file
Each individual flag is displayed as a single character, in this order:
r -- file data is stored in the realtime section
p -- file has preallocated extents (cannot be changed using chattr)
i -- immutable, file cannot be modified
a -- append-only, file can only be appended to
s -- all updates are synchronous
A -- the access time is not updated for this inode
d -- do not include this file in a dump of the filesystem
t -- child created in this directory has realtime bit set by default
P -- child created in this directory has parents project ID by default
n -- symbolic links cannot be created in this directory
e -- for non-realtime files, observe the inode extent size value
E -- children created in this directory inherit the extent size value
f -- do not include this file when defragmenting the filesystem
S -- enable filestreams allocator for this directory
Options:
-R -- recursively descend (useful when current file is a directory)
-D -- recursively descend, but only list attributes on directories
-a -- show all flags which can be set alongside those which are set
-v -- verbose mode; show long names of flags, not single characters
