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

Question

I have the following characters being repeated at the end of every line:

^[[00m 

How can I remove them from each line using the Vim editor?

When I give the command :%s/^[[00m//g, it doesn't work.

Answer 1

You could use :%s/.\{6}$// to literally delete 6 characters off the end of each line.

The : starts ex mode which lets you execute a command. % is a range that specifies that this command should operate on the whole file. The s stands for substitute and is followed by a pattern and replace string in the format s/pattern/replacement/. Our pattern in this case is .\{6}$ which means match any character (.) exactly 6 times (\{6}) followed by the end of the line ($) and replace it with our replacement string, which is nothing. Therefore, as I said above, this matches the last 6 characters of every line and replaces them with nothing.
