What do you mean by negative indexes?
- ratrocket 4y agoI believe "negative index" means array[-1] is the last element in array, array[-2] is the second-to-last element, etc. In the context of "cut", it would mean being able to do something like: cut -d" " -f1--2 the "-f1--2" (read: fields from 1 to minus 2; it's a range) means to select from the first field to the second-to-last field. (that double "--" is pretty awkward, to be sure!) Some programming languages (ruby is the one that I know) have this feature for accessing array elements.
