DESCRIPTION

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.)

-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:

opaque	set the opaque flag (owner or super-user only)
nodump	set the nodump flag (owner or super-user only)
sappnd	set the system append-only flag (super-user only)
schg	set the system immutable flag (super-user only)
uappnd	set the user append-only flag (owner or super-user only)
uchg	set the user immutable flag (owner or super-user only)

Putting the letters “no” before an option causes the flag to be turned off. For example:

nouchg	the immutable bit should be cleared

Symbolic links do not have flags, so unless the -H or -L option is set, chflags on a symbolic link always succeeds and has no effect. 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.
