Been a long time since I've logged in and had a question, but here goes nothing!
I have a file that is not delimited in any way, but I need to replace a particular column character from a space to a alphanumeric value on every other line starting at line 2; in this case an "L". Here is a quick rundown of what the file would look like vs. what I would like it to look like:
Header 1234 asdf123 skip this 5678 asdf567
So, after what I'm assuming would be some sort of "awk" command to replace the 9th character in the even lines, I would like the file to look like this:
Header 1234 L asdf123 skip this 5678 L asdf567
My scripting is a bit rusty, as I haven't had to do much for my job in the past year or two. If you guys could give me any kind of help, it would be much appreciated.
