file flags

[-h ] [-R

file ... |
The chflags
utility modifies the file
flags of the listed files as specified by the flags
operand. The flags of a file dictate special
restrictions beyond those enforced by its mode/permissions. Only the
superuser can change the user flags on block and character devices.
You can use
ls
-lo
to see the flags of existing files.
The options are as follows:
-H
-R
option is also specified, symbolic links
on the command line are followed. Symbolic links encountered in the tree
traversal are not followed.-h
-h
and -R
options are mutually exclusive.-L
-R
option is also specified, all symbolic
links are followed.-P
-R
option is also specified, no symbolic
links are followed.-R
Flags are a comma separated list of keywords. The following keywords are currently defined:
arch
nodump
sappnd
schg
uappnd
uchg
The arch
flag is for compatibility only,
and currently has no effect.
A file with the nodump
flag set will by
default only be backed up by
dump(8) during full backups.
The -h
option of
dump(8) can be used to alter
this.
An immutable file may not be changed, moved, or deleted. An append-only file is immutable except that data may be appended to it.
The superuser-settable sappnd
and
schg
flags can be set at any time, but may only be
cleared when the system is running at security level 0 or -1 (insecure or
permanently insecure mode, respectively). For more information on setting
the system security level, see
securelevel(7).
Putting the letters no
before a flag name
causes the flag to be turned off. For example:
nouchg
The -H
, -L
, and
-P
options are ignored unless the
-R
option is specified. In addition, these options
override each other and the command's actions are determined by the last one
specified.
The chflags
utility exits 0 on
success, and >0 if an error occurs.
ls(1), chflags(2), stat(2), fts_open(3), securelevel(7), symlink(7), dump(8)
The chflags
command first appeared in
4.4BSD.
