NAME
chflags —
change file flags
SYNOPSIS
chflags |
[-R
[-H | -L |
-P]]
[-h] flags
file ... |
DESCRIPTION
The
chflags utility modifies the file flags of the listed
files as specified by the
flags operand.
The options are as follows:
-
-
- -H
- If the -R option is specified, symbolic
links on the command line are followed. (Symbolic links encountered in the
tree traversal are not followed.)
-
-
- -h
- If the file or a file encountered
during directory traversal is a symbolic link, the file flags of the link
itself is changed.
-
-
- -L
- If the -R option is specified, all
symbolic links are followed.
-
-
- -P
- If the -R option is specified, no
symbolic links are followed.
-
-
- -R
- Change the file flags for the file hierarchies rooted in
the files instead of just the
files themselves.
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 an option causes the flag to be
turned off. For example:
-
-
- nouchg
- 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.
EXIT STATUS
The
chflags utility exits 0 on success, and >0 if
an error occurs.
