I'm in a quandary. MacOS has been on Bash 3.2.X for a long time, while Ubuntu is on 4.4.X. And instead of upgrading Bash, the folks at Apple have decided to switch the default shell to `zsh`. And to make matters worse, they've made it very hard to upgrade bash and have the default version be something else.
So what's a developer to do? And I can hear a bunch of you saying "Get an Ubuntu machine". I've thought about it. I even asked for one, especially since my current MBP is, shall we say, sick, but all they offered was a little 13" MBP. I've also got an Ubuntu desktop in the office I
ssh into all the time. If nothing else it's got better upload speed than going through the VPN from home.
So here's my dilemma. Sort of upgrade Bash on my current MBP and figure out how to beat it into submission, which has the benefit of matching what our official build systems and clusters run, but struggle against our Apple overlords every time they update the OS, or switch to
zsh, which, admittedly is a nice experience, and will just work across OS updates, but means my local scripts either still need to use Bash 3.2.X or I have to either duplicate them for two shells, restrict them to the subset of commands that work with both, or struggle against Apple and upgrade the version of bash.
I'm thinking the best thing to do is just figure out (and document) all of the machinations to get my MBP running Bash 4.4.X as it's primary shell and just keep it that way. What do you all think, and if you've done it, got any documentation?
