Over the past couple of decades, I have used several Unix tools, and have amassed a pretty good collection of notes, tips, and tricks on many of them. I've been meaning to put them all out on github or something, but sadly, much of my material is probably dated, or at least needs to be checked. At the very least, it needs a good cleanup before I can do that.
A bit of a catch-22 there.
Instead, I decided to start with something I've only just begun using, and add other stuff later.
I had been somewhat happy with the file manager I had been using for some years, having learnt to live with it's somewhat baroque configuration requirements (involving 4 different files -- 2 custom syntaxes, 1 shell, and 1 python!)
But the urge to move on was there, and one weekend I started looking around, eventually finding vifm.
It has some really nice features that I explore in vifm.mkd.
