chflags utility modifies the file flags of the
listed files as specified by the flags operand.
The options are as follows:
-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.-RFlags 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:
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.
chflags utility exits 0 on success,
and >0 if an error occurs.
