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
1.9 aaron 99: An immutable file may not be changed, moved, or deleted.
100: An append-only file is immutable except that data may be appended to it.
101: .Pp
1.1 deraadt 102: Putting the letters
103: .Dq no
1.9 aaron 104: before a flag name causes the flag to be turned off.
1.1 deraadt 105: For example:
106: .Bd -literal -offset indent compact
107: nouchg the immutable bit should be cleared
108: .Ed
1.8 aaron 109: .Pp
110: The
1.9 aaron 111: superuser-settable
1.8 aaron 112: .Dq sappnd
113: and
114: .Dq schg
1.9 aaron 115: flags can be set at any time, but may only be cleared when the system is
116: running at security level 0 or -1 (insecure or permanently insecure mode,
117: respectively).
118: The securelevel is normally set to 0, for example, when
119: running in single-user mode.
1.1 deraadt 120: .Pp
121: Symbolic links do not have flags, so unless the
122: .Fl H
123: or
124: .Fl L
125: option is set,
1.5 aaron 126: .Nm
1.1 deraadt 127: on a symbolic link always succeeds and has no effect.
128: The
129: .Fl H ,
130: .Fl L
131: and
132: .Fl P
133: options are ignored unless the
134: .Fl R
135: option is specified.
136: In addition, these options override each other and the
137: command's actions are determined by the last one specified.
1.6 deraadt 138: .Pp
139: Only the super-user can change the user flags on block and
140: character devices.
1.1 deraadt 141: .Pp
1.10 ! aaron 142: You can use
! 143: .Ic ls -lo
! 144: to see the flags of existing files.
1.3 deraadt 145: .Pp
1.1 deraadt 146: The
1.5 aaron 147: .Nm
1.4 aaron 148: utility exits 0 on success or >0 if an error occurred.
