I used lsd before switching to exa. BTW I was the one who suggested to integrated hyperlink option to lsd. :-) Not saying it wouldn’t be added otherwise, but at least it sped up the process back then.^^
On the topic of filesystem boundaries, this is something I always have in mind. Hardlinks in example cannot be on two different drives, by its nature. It’s an option I use with my own du script often: -x . It helps to keep things in check and simplifies some things, as I have a complex of multiple drives that are mounted into my home from various places, plus the symbolic links from Steam and so on. Avoiding other filesystems is part of my “workflow”, if you so will and would like to see such an option as well.
I just noticed exa has an option -H or –links to list each file’s number of hard links. So at least it is aware of hardlinks and could calculate the total size correctly.
