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 is a symbolic link, change the mode of the link itself rather than the file to which it points.
-L
If the -R option is specified, all symbolic links are followed.
-P
If the -R option is specified, no symbolic links are followed. This is the default.
-R
Change the file flags for the file hierarchies rooted in the files instead of just the files themselves.
The flags are specified as an octal number or a comma separated list of keywords. The following keywords are currently defined:
arch, archived
set the archived flag (super-user only)
opaque
set the opaque flag (owner or super-user only)
nodump
set the nodump flag (owner or super-user only)
sappnd, sappend
set the system append-only flag (super-user only)
schg, schange, simmutable
set the system immutable flag (super-user only)
sunlnk, sunlink
set the system undeletable flag (super-user only)
uappnd, uappend
set the user append-only flag (owner or super-user only)
uchg, uchange, uimmutable
set the user immutable flag (owner or super-user only)
uunlnk, uunlink
set the user undeletable flag (owner or super-user only)
Putting the letters "no" before or removing the letters "no" from a keyword causes the flag to be cleared. For example:
nouchg
clear the user immutable flag (owner or super-user only)
dump
clear the nodump flag (owner or super-user only)
Unless the -H , -L , or -h options are given, 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.
You can use "ls -lo" to see the flags of existing files.
