39.Sh NAME
40.Nm mv
41.Nd move files
42.Sh SYNOPSIS
43.Nm mv
44.Op Fl fi
45.Ar source target
46.Nm mv
47.Op Fl fi
48.Ar source ... directory
49.Sh DESCRIPTION
50In its first form, the
51.Nm
52utility renames the file named by the
53.Ar source
54operand to the destination path named by the
55.Ar target
56operand.
57This form is assumed when the last operand does not name an already
58existing directory.
59.Pp
60In its second form,
61.Nm
62moves each file named by a
63.Ar source
64operand to a destination specified by the
65.Ar directory
66operand.
67It is an error if the
68.Ar directory
69operand does not exist.
70The destination path for each
71.Ar file
72operand is the pathname produced by the concatenation of the
73.Ar directory
74operand, a slash, and the final pathname component of the named file.
75.Pp
76The options are as follows:
77.Bl -tag -width Ds
78.It Fl f
79Do not prompt for confirmation before overwriting the destination
80path.
81.It Fl i
82Causes
83.Nm
84to write a prompt to standard error before moving a file that would
85overwrite an existing file.
86If the response from the standard input begins with the character
87.Dq y ,
88the move is attempted.
89.El
90.Pp
91The last of any
92.Fl f
93or
94.Fl i
95options is the one which affects
96.Nm mv Ns 's
97behavior.
98.Pp
99If the destination path does not have a mode which permits writing,
100.Nm
101prompts the user for confirmation as specified for the
102.Fl i
103option.
104.Pp
105As the
106.Xr rename 2
107call does not work across file systems,
108.Nm
109uses
110.Xr cp 1
111and
112.Xr rm 1
113to accomplish the move.
114The effect is equivalent to:
115.Bd -literal -offset indent
116$ rm -f destination_path && \e
117    cp -PRp source_file destination && \e
118    rm -rf source_file
119.Ed
120.Pp
121.Ex -std mv
122.Sh EXAMPLES
123Rename file
124.Pa foo
125to
126.Pa bar ,
127overwriting
128.Pa bar
129if it already exists:
130.Pp
131.Dl $ mv -f foo bar
132.Pp
133Either of these commands will rename the file
134.Pa -f
135to
136.Pa bar ,
137prompting for confirmation if
138.Pa bar
139already exists:
140.Bd -literal -offset indent
141$ mv -i -- -f bar
142$ mv -i ./-f bar
143.Ed
144.Sh SEE ALSO
145.Xr cp 1 ,
146.Xr symlink 7
147.Sh STANDARDS
148The
149.Nm
150utility is compliant with the
151.St -p1003.1-2004
152specification.
153.Sh HISTORY
154A
155.Nm
156command appeared in
157.At v1 .
158.Sh CAVEATS
159In the second synopsis form
160if the destination path exists,
161the
162.Ar source
163operand and the destination path
164must both be a file or must both be a directory
165for the operation to succeed.
166For example, if
167.Pa f
168is a file and
169.Pa d
170and
171.Pa d/f
172are directories, the following command will fail:
173.Pp
174.Dl $ mv f d
