Replace based on an exact position
Trying to use sed - but having no luck.
I have a text file - I want to replace whatever character is in position 106, 157 and 237 w/ the string "xxx". Want this change for all lines w/in that text file.
I'm open to using awk or whatever command would be best for replacing characters based on the exact position. Seems like sed can do a lot, but for whatever reason, have had no luck figuring out how to replace on just position alone.
Thanks much!
