mv

Command Function

This command is used to move files.

Syntax

mv [-fivn] SOURCE… DEST

Parameters

Table 1 Parameter description

Parameter	Description	Value Range
-help	Displays help information.	N/A
-f	Forcibly overwrites the target file.	N/A
-i	Provides information before moving a file that would overwrite an existing file or directory. Enter y to overwrite the file or directory, and enter n to cancel the operation.	N/A
-n	Do not overwrite any existing file or directory.	N/A
-v	This parameter does not take effect although it is supported by the latest Toybox code.	N/A
SOURCE	Specifies the file to move.	This command cannot be used to move a directory. It can be used to move multiple files at a time.
DEST	Specifies the destination file path.	Both a directory and a file are supported.

Usage Guidelines

SOURCEFILE supports wildcard characters * and ?. The asterisk (*) indicates any number of characters, and the question mark (?) represents a single character. DEST does not support wildcard characters. If the specified SOURCE matches multiple files, DEST must be a directory.
If DEST is a directory, this directory must exist. In this case, the destination file is named after the source file.
If DEST is a file, the directory for this file must exist.
If the destination file already exists, it will be overwritten.

Note

Currently, the shell does not support this command. mksh supports it. To switch to mksh, run cd bin and ./mksh.

Example

Run the following commands:

mv -i test.txt testpath/
mv test?.txt testpath/ (Move test3.txt, testA.txt, and test_.txt)

Output

Example 1: Move a file.

OHOS:/$ touch test.txt
OHOS:/$ mkdir testpath
OHOS:/$ touch testpath/test.txt
OHOS:/$ mv -i test.txt testpath/
mv: overwrite 'testpath//test.txt' (Y/n):y
OHOS:/$ ls
bin  etc  proc    storage  testpath  usr
dev  lib  sdcard  system   userdata  vendor
OHOS:/$ cp testpath/test.txt ./
OHOS:/$ ls
bin  etc  proc    storage  test.txt  userdata  vendor
dev  lib  sdcard  system   testpath  usr
OHOS:/$ mv -i test.txt testpath/
mv: overwrite 'testpath//test.txt' (Y/n):n
OHOS:/$ ls
bin  etc  proc    storage  test.txt  userdata  vendor
dev  lib  sdcard  system   testpath  usr

Example 2: Move files.

OHOS:/$ ls
bin  etc  proc    storage  test.txt   testA.txt  testpath  usr
dev  lib  sdcard  system   test3.txt  test_.txt  userdata  vendor
OHOS:/$ mv test?.txt testpath/
OHOS:/$ ls
bin  etc  proc    storage  test.txt  userdata  vendor
dev  lib  sdcard  system   testpath  usr
OHOS:/$ ls testpath/
test.txt  test3.txt  testA.txt  test_.txt
