The chflags
utility modifies the file
flags of the listed files as specified by the flags
operand.
The options are as follows:
-d
-H
-R
option is specified, symbolic links on
the command line are followed. Symbolic links encountered in the tree
traversal are not followed.-h
-L
-R
option is specified, all symbolic links
are followed.-P
-R
option is specified, no symbolic links
are followed.-R
Flags are a comma separated list of keywords. The following keywords are currently defined:
Keyword | Flag | Permission |
arch |
archived | super-user only |
opaque |
opaque | owner or super-user |
nodump |
nodump | owner or super-user |
sappnd |
system append-only | super-user only |
schg |
system immutable | super-user only |
uappnd |
user append-only | owner or super-user |
uchg |
user immutable | owner or super-user |
Putting the letters ‘no
’
before a keyword causes the flag to be turned off. For example,
nouchg
requests the immutable bit should be
cleared.
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 default is as if the -P
option had
been specified.
The -o
option of
ls(1) is used to display the
flags.
The kernel does not allow the flags on block and character devices to be changed except by the super-user.
Note that the ability to clear certain flags is dependent on the current kernel securelevel. See secmodel_securelevel(9) for details.
The chflags
utility exits 0 on
success, and >0 if an error occurs.
