New features in the fish shell

For me, I don't use the history suppression very often, but occasionally I want to use a command that requires, say, passing a password as an argument (not ideal, but sometimes unavoidable), or something that will pollute history searches (which I make heavy use of). A leading space is something I rarely do accidentally, but is easy to do and easy to remember when I want it.

In addition to the sensitive information / password use-case already mentioned, I've picked up the habit of excluding potentially catastrophic and destructive commands like, let's say,

rm -rf ./*

or dropping database tables, etc. from the search history. Before learning about history suppression in my younger years (i.e. back when I tended to be prone to getting nervous during an incident with a critical system or when I sometimes would grow impatient while working over high-latency ssh connections), I've had several jump-scares when, by "typing ahead" not only commands but retrieving items from the history with the arrow keys, found that I accidentially ended up with the "interesting side-effects if run here and now" kind of command. Luckily always before hitting enter, but still.

It's not a fool-proof system, but I find it quite useful in the "better safe than sorry" kind of way.

Cheers,

You could start by explaining why you dislike the feature, I'm curious :-) Lots of copy/paste?
