I’m using Fish, rather than Bash, and it has type-ahead suggestions, which help a lot.
So, I’ll type rsync and then it’ll show inline that I typed rsync -ah --info=progress2 a long time ago. And then I’ll be like, oh wow, this past-me-guy was very smart, I’ll be having the same.
Obviously, this is an imperfect system. If you run another rsync command without these flags, it won’t directly show these flags next time, because it’s not the most recent entry in history.
But it’s rare that I know I’ll want to run a command again in a few months, so it’s still really helpful.
And of course, there is nothing stopping me from creating aliases and scripts as well.
