I must admit I only use ed(1) (of sbase) these days. It has been like this for a year or so.
There are a couple things I've come across the sbase's version of ed: 1. w doesn't print the byte count. Suppose a sample ed session (using P to distinguish my input from ed's output): % ed P *a milk bread eggs meat veggies bananas apples . *w list *q % 2. I guess using ed for huge files is not really a good idea, however the sbase ed cannot open a 750MiB 3.5m lines CSV file, while the GNU version can. Probably has to do with the limits set. As always, I'm very pleased working with sbase and want to thank everybody responsible for making it. Cheers -- caóc
