Here’s how to use movefile() function.
Description:
Move, delete, or rename a file.
Syntax:
movefile(fn:z,path)
Note:
The function moves file fn to a file specified by parameter path. Delete file fn if path is absent; rename the file if only the file name is specified in the path.
Parameter:
|
fn |
File name |
|
z |
An integer; it represents the zone table number when parameter fn is a homo-name files group; or is omitted when fn isn’t a homo-name files group |
|
path |
The path (with file name) along which the file is moved, or a file name |
Option:
|
@y |
Force an execution of the function if the target file already exists. Without the option you can’t force an execution. Delete the target file if parameter path is absent. |
|
@c |
Copy the file. If the target file name is the same as that of the specified file to which it will be moved, the copy fails. |
|
@p |
path is relative to the main directory when it is a relative path; default is relative to fn’s parent directory |
Return value:
Boolean value
Example:
|
|
A |
|
|
1 |
=movefile("E://test.property","D://testfile.property") |
Move the file to testfile.property file under root directory on driver D |
|
2 |
=movefile("D://testfile.property","file.property") |
D://testfile.property is renamed file.property |
|
3 |
=movefile("D://file.property") |
Delete file.property |
|
4 |
=movefile@y("E://test1.property","D://testfile1.property") |
The file testfile1.property already exists. Force the move and override the original file |
|
5 |
=movefile@c("D://testfile1.property","file.property") |
Copy the file, instead of renaming it |
|
6 |
=movefile@cy("E://test2.property","D:// file.property") |
file.property already exists. Force the copy and override the original file |
|
7 |
=movefile@y("D://testfile1.property") |
Delete testfile1.property |
|
8 |
=movefile@cp("D://testfile1.property","file.property") |
Copy the file to the main directory and rename it file.property |
Related function:
Description:
Move a file from a node to another.
Syntax:
Note:
The function moves file fn on node h, which is the local machine when omitted, to path path on node hs, which can be a node sequence. It renames fn when hs is absent, deletes fn when both path and hs are absent, removes files on hs when path and h are absent but hs is non-null.
Parameter:
|
fn |
A file name |
|
h |
A node |
|
path |
A path (that contains file name) to which a file is moved, or a file name |
|
hs |
A node or a node sequence |
Option:
|
@y |
Force moving to overwerite a namesake file while default is failure, and deletion when path is null; |
|
@c |
Copy the file, and the copy fails if there is already a namesake file |
Return value:
Boolean
Example:
|
|
A |
|
|

3 |
=movefile("D:/t2.txt",["192.168.31.165:8281"];"t2_new.txt") |

=movefile("D:/t2_new.txt",["192.168.31.165:8281"];) |
Delete the specified file since both parameter path and parameter hs are absent |
|
5 |
=movefile("D:/p1/tmp.txt";,["192.168.31.39:8281"]) |
Delete D:/p1/tmp.txt on node "192.168.31.39:8281" since parameter h and parameter path are absent but parameter hs is non-null |
