mv - move files
mv [-fi] source target mv [-fi] source ... directory
In its first form, the mv utility renames the file named by the source operand to the destination path named by the target operand. This form is assumed when the last operand does not name an already existing directo- ry. In its second form, mv moves each file named by a source operand to a destination file in the existing directory named by the directory operand. The destination path for each operand is the pathname produced by the concatenation of the last operand, a slash, and the final pathname component of the named file. The options are as follows: -f Do not prompt for confirmation before overwriting the destination path. -i Causes mv to write a prompt to standard error before moving a file that would overwrite an existing file. If the response from the standard input begins with the character "y", the move is at- tempted. The last of any -f or -i options is the one which affects mv's behavior. It is an error for either the source operand or the destination path to specify a directory unless both do. If the destination path does not have a mode which permits writing, mv prompts the user for confirmation as specified for the -i option. As the rename(2) call does not work across file systems, mv uses cp(1) and rm(1) to accomplish the move. The effect is equivalent to: $ rm -f destination_path && \ cp -PRp source_file destination && \ rm -rf source_file The mv utility exits 0 on success or >0 if an error occurred.
$ mv -f foo bar Rename file foo to bar, overwriting bar if it already exists. $ mv -i -- -f bar $ mv -i ./-f bar Either of these commands will rename the file -f to bar, prompting for confirmation if bar already exists.
The mv utility is expected to be IEEE Std 1003.2 ("POSIX.2") compatible.
A mv command appeared in Version 1 AT&T UNIX. MirOS BSD #10-current May 31, 1993 1
