1.1 deraadt 54: .Sh DESCRIPTION
55: The
1.5 aaron 56: .Nm
1.1 deraadt 57: utility modifies the file flags of the listed files
58: as specified by the
59: .Ar flags
60: operand.
1.7 aaron 61: The
62: .Ar flags
63: of a file dictate special restrictions beyond those enforced by its
64: mode/permissions.
1.1 deraadt 65: .Pp
66: The options are as follows:
67: .Bl -tag -width Ds
1.7 aaron 68: .It Fl R
69: Recursively descend through any specified directory arguments.
70: Change the flags of the file hierarchies rooted
71: in the files instead of just the files themselves.
1.1 deraadt 72: .It Fl H
73: If the
74: .Fl R
1.7 aaron 75: option is also specified, symbolic links on the command line are followed.
1.1 deraadt 76: (Symbolic links encountered in the tree traversal are not followed.)
77: .It Fl L
78: If the
79: .Fl R
1.7 aaron 80: option is also specified, all symbolic links are followed.
1.1 deraadt 81: .It Fl P
82: If the
83: .Fl R
1.7 aaron 84: option is also specified, no symbolic links are followed.
1.1 deraadt 85: .El
86: .Pp
87: Flags are a comma separated list of keywords.
88: The following keywords are currently defined:
89: .Bd -literal -offset indent compact
90: arch set the archived flag
91: opaque set the opaque flag (owner or super-user only)
92: nodump set the nodump flag (owner or super-user only)
93: sappnd set the system append-only flag (super-user only)
94: schg set the system immutable flag (super-user only)
95: uappnd set the user append-only flag (owner or super-user only)
96: uchg set the user immutable flag (owner or super-user only)
97: .Ed
98: .Pp
99: Putting the letters
100: .Dq no
101: before an option causes the flag to be turned off.
102: For example:
103: .Bd -literal -offset indent compact
104: nouchg the immutable bit should be cleared
105: .Ed
1.8 ! aaron 106: .Pp
! 107: The
! 108: .Dq sappnd
! 109: and
! 110: .Dq schg
! 111: system flags may be set at any time, but normally may only be unset when the
! 112: system is in single-user mode (see
! 113: .Xr init 8
! 114: for details).
1.1 deraadt 115: .Pp
116: Symbolic links do not have flags, so unless the
117: .Fl H
118: or
119: .Fl L
120: option is set,
1.5 aaron 121: .Nm
1.1 deraadt 122: on a symbolic link always succeeds and has no effect.
123: The
124: .Fl H ,
125: .Fl L
126: and
127: .Fl P
128: options are ignored unless the
129: .Fl R
130: option is specified.
131: In addition, these options override each other and the
132: command's actions are determined by the last one specified.
1.6 deraadt 133: .Pp
134: Only the super-user can change the user flags on block and
135: character devices.
1.1 deraadt 136: .Pp
1.3 deraadt 137: You can use "ls -lo" to see the flags of existing files.
138: .Pp
1.1 deraadt 139: The
1.5 aaron 140: .Nm
1.4 aaron 141: utility exits 0 on success or >0 if an error occurred.
