chattr(1)chattr(1)NAME
chattr, lsattr - change or list file attributes
SYNOPSISchattr [-R|-D] [+-rdtPn] file ...
lsattr [-R|-D] file ...
DESCRIPTIONchattr changes the file attributes on an XFS filesystem. This mechanism
enables and disables particular properties for individual files and
directories.
The operator `+' causes the selected attributes to be added to the
existing attributes of the files; `-' causes them to be removed.
The letters `rdtPn' select the new attributes for the files: realtime
(r), no dump (d), realtime inheritance (t), project inheritance (P), and
no symbolic links (n).
lsattr lists the current set of attributes of a file.
OPTIONS-R Recursively change or list attributes of directories and their
contents. Symbolic links encountered during recursive directory
traversals are ignored.
-D Recursively change or list attributes of directories only.
ATTRIBUTES
(r) The file is a realtime file.
(d) The file should be skipped by backup utilities.
(t) Realtime inheritance bit - new files created in the directory
will be automatically realtime, and new directories created in
the directory will inherit the inheritance bit.
(P) New files created in the directory will have the project ID of
the directory, and new directories created in the directory
will inherit the inheritance bit.
(n) Symbolic links cannot be created in this directory.
