Hello! I have a file that looks like this: Where every line beginning with a T is a new data set. So basically I need each line in the file to look like this: I need to merge every other line so that each data set lies on the same line. There can just be a space in between the two data points, a comma is not necessary. So what's the easiest way to go about doing this? I was thinking something along the lines of sed, awk, or grep. Help is greatly appreciated.
