# Replace Filename Command

This is an example to replace "\[天堂www.\*.com]" in the video file name.

Create a `rename.bat` file with command below:

```
@echo off
Powershell.exe -executionpolicy remotesigned -File ./rename.ps1
# pause
```

Create a `rename.ps1` file with command below:

```
# Replace [天堂www.*.com] from video file name
$stringToReplace = -join([regex]::Escape("[天堂"), "www.*.com", [regex]::Escape("]"))
ls *.avi,*.mp4,*.mkv | ren -NewName {$_.name -replace $stringToReplace,""}
```

Put both `rename.bat` and `rename.ps1` in the video folder, click on the `rename.bat` and it will execute powershell command `rename.ps1`

## Expected Result

* \[天堂www\.abc.com]video\_001.avi --> video\_001.avi
* \[天堂www\.abc.com]video\_002.mp4 --> video\_002.mp4
* \[天堂www\.abc.com]video\_003.mkv --> video\_003.mkv
