  65 .Sh DESCRIPTION
  66 The file(s) are copied
  67 to the target file or directory.
  68 If the destination is a directory, then the
  69 .Ar file
  70 is copied into
  71 .Ar directory
  72 with its original filename.
  73 If the target file already exists, it is
  74 either renamed to
  75 .Ar file Ns Pa .old
  76 if the
  77 .Fl b
  78 option is given
  79 or overwritten
  80 if permissions allow.
  81 An alternate backup suffix may be specified via the
  82 .Fl B
  83 option's argument.
  84 .Pp
  85 The options are as follows:
  86 .Bl -tag -width indent
  87 .It Fl b
  88 Back up any existing files before overwriting them by renaming
  89 them to
  90 .Ar file Ns Pa .old .
  91 See
  92 .Fl B
  93 for specifying a different backup suffix.
  94 .It Fl B Ar suffix
  95 Use
  96 .Ar suffix
  97 as the backup suffix if
  98 .Fl b
  99 is given.
 100 .It Fl C
 101 Copy the file.
 102 If the target file already exists and the files are the same,
 103 then don't change the modification time of the target.
 104 .It Fl c
 105 Copy the file.
 106 This is actually the default.
 107 The
 108 .Fl c
 109 option is only included for backwards compatibility.
 110 .It Fl d
 111 Create directories.
 112 Missing parent directories are created as required.
 113 .It Fl f
 114 Specify the target's file flags; see
 115 .Xr chflags 1
 116 for a list of possible flags and their meanings.
 117 .It Fl g
 118 Specify a group.
 119 A numeric GID is allowed.
 120 .It Fl M
 121 Disable all use of
 122 .Xr mmap 2 .
 123 .It Fl m
 124 Specify an alternate mode.
 125 The default mode is set to rwxr-xr-x (0755).
 126 The specified mode may be either an octal or symbolic value; see
 127 .Xr chmod 1
 128 for a description of possible mode values.
 129 .It Fl o
 130 Specify an owner.
 131 A numeric UID is allowed.
 132 .It Fl p
 133 Preserve the modification time.
 134 Copy the file, as if the
 135 .Fl C
 136 (compare and copy) option is specified,
 137 except if the target file doesn't already exist or is different,
 138 then preserve the modification time of the file.
 139 .It Fl S
 140 Safe copy.
 141 Normally,
 142 .Nm
 143 unlinks an existing target before installing the new file.
 144 With the
 145 .Fl S
 146 flag a temporary file is used and then renamed to be
 147 the target.
 148 The reason this is safer is that if the copy or
 149 rename fails, the existing target is left untouched.
 150 .It Fl s
 151 .Nm
 152 exec's the command
 153 .Xr strip 1
 154 to strip binaries so that
 155 .Nm
 156 can be portable over a large
 157 number of systems and binary types.
 158 .It Fl v
 159 Causes
 160 .Nm
 161 to show when
 162 .Fl C
 163 actually installs something.
 164 .El
 165 .Pp
 166 By default,
 167 .Nm
 168 preserves all file flags, with the exception of the
 169 .Dq nodump
 170 flag.
 171 .Pp
 172 The
 173 .Nm
 174 utility attempts to prevent moving a file onto itself.
 175 .Pp
 176 Installing
 177 .Pa /dev/null
 178 creates an empty file.
 179 .Sh DIAGNOSTICS
 180 The
 181 .Nm
 182 utility exits 0 on success, and 1 otherwise.
 183 .Sh FILES
 184 .Bl -tag -width INS@XXXX -compact
 185 .It Pa INS@XXXX
 186 If either
 187 .Fl S
 188 option is specified, or the
 189 .Fl C
 190 or
 191 .Fl p
 192 option is used in conjuction with the
 193 .Fl s
 194 option, temporary files named
 195 .Pa INS@XXXX ,
 196 where
 197 .Pa XXXX
 198 is decided by
 199 .Xr mkstemp 3 ,
 200 are created in the target directory.
 201 .El
 202 .Sh COMPATIBILITY
 203 Historically
 204 .Nm
 205 moved files by default.
 206 The default was changed to copy in
 207 .Fx 4.4 .

 217 .Sh HISTORY
 218 The
 219 .Nm
 220 utility appeared in
 221 .Bx 4.2 .
 222 .Sh BUGS
 223 Temporary files may be left in the target directory if
 224 .Nm
 225 exits abnormally.
 226 .Pp
 227 File flags cannot be set by
 228 .Xr fchflags 2
 229 over a NFS file system.  Other file systems do not have a concept of flags.
 230 .Nm
 231 will only warn when flags could not be set on a file system
 232 that does not support them.
 233 .Pp
 234 .Nm
 235 with
 236 .Fl v
 237 falsely says a file is copied when
 238 .Fl C
 239 snaps hard links.
