How do I remove the last six characters of every line in Vim? -

I'm repeating the following characters at the end of each line:

  ^ [ [00m   
 How can I remove them from each row using the Vim editor?  
 When I command :% s / ^ [[00m / / G , it does not work.   
 
 
 You :% S / \ {6} $ //  literally deletes 6 characters from the end of each line.  
 :  starts with the start mode that lets you execute a command. %  is a range that specifies that this command should work on the whole file. Stands for  s  option and changes the string after a pattern and in the format  s / pattern / replace / . In this case our pattern is . \ {6} $  means the exact 6 times ( \ {6} ) from any character (. ) After the end of the line ( $ ) and replace it with our replacement string, which is nothing, so, as I said above, it matches the last 6 letters of each row and they Without changing some space
