Modern system utility replacements (Go / Rust or even just something new)

Interesting and Modern CLI Tools

The absolute requirement is that these must be binaries that could go into /usr/bin one day. No python, ruby or js stuff. Not that dynamic languages are bad/evil, but I think system utilities should be binaries. I also think it's interesting that people are writing replacements in Go/Rust/Other that rethink some unix legacy. Replacement doesn't mean better in all cases. I just think it's an interesting time but also a good measure of what these compiled languages can handle/tackle/address. Will we see larger and more impressive CLIs? Or will the feature sets be about the same but the quality/stability/safety be better?

It's going to be reductive to explain some of these tools in one line.

  • exa - ls replacement
  • caddy - HTTP server (better than python -m SimpleHTTPServer)

Automating Java Upgrades with Homebrew and Jenv


  • never upgrade Java with the GUI pkg installer again.
  • never try to remember that /Library/Java is where JDKs go.
  • Just keep JDK8 and JDK9 up-to-date. Java is so stable, maybe these two major versions is all we need?

Note the assumptions in these goals. Making this a bit more generic would be nice.

I'm on a mac and I use the fish shell which I know is squarely in the edge case camp but I hope this is inspiring or useful to someone else because there's not much shell specific stuff here. I found jenv which is going to help.

First, upgrading java with homebrew is pretty easy. The assumption is that java8 is stable and java (9) is still emerging. This assumption would likely change so it'd be nice to have this scripted out of this assumption. For now, I'm just trying to avoid graphical Oracle installers.

Fish Shell Awesomeness
View fish_shell_switch.txt
Early days of fish shell impressions.
This is like honeymoon time but I really like it so far.
1. iTerm
alt+command goes back in history. Weird. Thought this was tab-navigation in iTerm.
2. Editing past commmands!
up & down to go through history (as usual) but then left-right take you into edit mode!
But how would you add a newline? Fish doesn't like `;` as much as zsh for newlines.
Well ... you can hit alt+enter and it will do a soft return!
