a file or folder's flags.
chflags [-R [-H | -L | -P]] flags file ...
-R Recurse: Change the file flags of file hierarchies rooted in the files
instead of just the files themselves.
-R -H Follow symbolic links on the command line
(by default Symbolic links within the tree are not followed.)
-R -L All symbolic links are followed.
-R -P No symbolic links are followed. (default)
flags are specified as an octal number or a comma separated list of keywords.
hidden set the hidden flag [Hide item from GUI]
and keyword aliases - Owner or Super-user only:
opaque set the opaque flag
nodump set the nodump flag
uappnd, uappend set the user append-only flag
uchg, uchange, uimmutable set the user immutable flag
uunlnk, uunlink set the user undeletable flag
and keyword aliases - Ssuper-user only:
arch, archived set the archived flag
sappnd, sappend set the system append-only flag
schg, schange, simmutable set the system immutable flag
sunlnk, sunlink set the system undeletable flag
immutable flag is equivalent to locking the file in the Finder's Show Info box.
Putting the letters `no' before an option causes the flag to be turned off.
nouchg means the file can be changed (immutable bit cleared)
uchg means the file cannot be changed
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.
sappnd and schg flags may only be unset when the system is in single-user mode.
You can use "ls -lo" to see the flags of existing files.
return status is zero if the mode is successfully changed,and >0 if an error
