1.1 deraadt 48: .Sh DESCRIPTION
1.21 jmc 49: The
50: .Ar source
51: file(s) are copied to the
52: .Ar target
53: file or directory.
54: If the
55: .Ar target
56: file already exists, it is either renamed to
1.8 millert 57: .Ar file.old
1.9 aaron 58: if the
1.8 millert 59: .Fl b
60: option is given
61: or overwritten
1.20 jmc 62: if permissions allow.
63: An alternate backup suffix may be specified via the
1.8 millert 64: .Fl B
65: option's argument.
1.21 jmc 66: If the
67: .Fl d
68: option is given,
69: .Ar target
70: directories are created, and no files are copied.
1.8 millert 71: .Pp
1.10 aaron 72: The options are as follows:
1.20 jmc 73: .Bl -tag -width "-B suffix"
74: .It Fl B Ar suffix
75: Use
76: .Ar suffix
77: as the backup suffix if
78: .Fl b
79: is given.
1.8 millert 80: .It Fl b
81: Backup any existing files before overwriting them by renaming
1.9 aaron 82: them to
1.12 aaron 83: .Ar file.old .
84: See
1.8 millert 85: .Fl B
86: for specifying a different backup suffix.
1.3 millert 87: .It Fl C
88: Copy the file.
89: If the target file already exists and the files are the same,
90: then don't change the modification time of the target.
1.1 deraadt 91: .It Fl c
1.11 aaron 92: Copy the file.
93: This is actually the default.
94: The
1.3 millert 95: .Fl c
96: option is only included for backwards compatibility.
1.26 ! jasper 97: .It Fl D
! 98: Create all leading components of the target before installing into it.
1.3 millert 99: .It Fl d
1.9 aaron 100: Create directories.
1.3 millert 101: Missing parent directories are created as required.

104: .Fl f , p , S ,
105: or
106: .Fl s
107: options.
1.20 jmc 108: .It Fl f Ar flags
109: Specify the target's file
110: .Ar flags .
1.1 deraadt 111: (See
112: .Xr chflags 1
113: for a list of possible flags and their meanings.)
1.20 jmc 114: .It Fl g Ar group
115: Specify a
116: .Ar group .
1.11 aaron 117: A numeric GID is allowed.
1.20 jmc 118: .It Fl m Ar mode
119: Specify an alternate
120: .Ar mode .
1.1 deraadt 121: The default mode is set to rwxr-xr-x (0755).
122: The specified mode may be either an octal or symbolic value; see
1.11 aaron 123: .Xr chmod 1
1.1 deraadt 124: for a description of possible mode values.
1.20 jmc 125: .It Fl o Ar owner
126: Specify an
127: .Ar owner .
1.11 aaron 128: A numeric UID is allowed.
1.3 millert 129: .It Fl p

139: .Nm
140: unlinks an existing target before installing the new file.
141: With the
1.3 millert 142: .Fl S
143: flag a temporary file is used and then renamed to be
1.11 aaron 144: the target.

1.3 millert 146: rename fails, the existing target is left untouched.

1.11 aaron 148: .Nm
1.1 deraadt 149: exec's the command
