the file will not help, I just need to know the right command!

1. Change the substring 'light' to 'lux!... a. Just the first instance on the current line only. b. All instances on the current line only. C. All instances throughout the file. d. All instances on lines 146 to 163. e. Just the first instance on each line starting from the current line to the end of the file. NOTE: Don't use the c flag to limit the search results. You don't have to match whole words. To test your commands, try them with the cursor at the beginning of line 146. this line has two 'light' substrings in it so it's easy to see if you are picking up just the first instance in a line
