(Symbolic links encountered in the tree traversal are not followed.) .It Fl h If the .Ar file is a symbolic link, change the file flags of the link itself rather than the file to which it points. .It Fl L If the .Fl R option is specified, all symbolic links are followed. .It Fl P If the .Fl R option is specified, no symbolic links are followed. This is the default. .It Fl R Change the file flags for the file hierarchies rooted in the files instead of just the files themselves. .It Fl v Cause .Nm to be verbose, showing filenames as the flags are modified. If the .Fl v option is specified more than once, the old and new flags of the file will also be printed, in octal notation. .El .Pp The flags are specified as an octal number or a comma separated list of keywords. The following keywords are currently defined: .Pp .Bl -tag -offset indent -width ".Cm opaque" .It Cm arch , archived set the archived flag (super-user only) .It Cm opaque set the opaque flag (owner or super-user only). [Directory is opaque when viewed through a union mount] .It Cm nodump set the nodump flag (owner or super-user only) .It Cm sappnd , sappend set the system append-only flag (super-user only) .It Cm schg , schange , simmutable set the system immutable flag (super-user only) .It Cm uappnd , uappend set the user append-only flag (owner or super-user only) .It Cm uchg , uchange , uimmutable set the user immutable flag (owner or super-user only) .It Cm hidden set the hidden flag [Hide item from GUI] .El .Pp As discussed in .Xr chflags 2 , the .Ar sappnd and .Ar schg flags may only be unset when the system is in single-user mode. .Pp Putting the letters .Dq Ar no before or removing the letters .Dq Ar no from a keyword causes the flag to be cleared. For example: .Pp .Bl -tag -offset indent -width "nouchg" -compact .It Ar nouchg clear the user immutable flag (owner or super-user only) .It Ar dump clear the nodump flag (owner or super-user only) .El .Pp Unless the .Fl H or .Fl L options are given, .Nm on a symbolic link always succeeds and has no effect. The .Fl H , .Fl L and .Fl P options are ignored unless the .Fl R option is specified. In addition, these options override each other and the command's actions are determined by the last one specified. .Pp You can use "ls -lO" to see the flags of existing files. .Sh EXIT STATUS .Ex -std .Sh SEE ALSO .Xr ls 1 , .Xr chflags 2 , .Xr stat 2 , .Xr fts 3 , .Xr symlink 7 .Sh HISTORY The .Nm command first appeared in .Bx 4.4 . .Sh BUGS Only a limited number of utilities are .Nm aware. Some of these tools include .Xr ls 1 , .Xr cp 1 , .Xr find 1 , .Xr install 1 , .Xr dump 8 , and .Xr restore 8 . In particular a tool which is not currently .Nm aware is the .Xr pax 1 utility.
