If your script starts with , both bash and zsh will run it fine. The bigger problem is the programs, filesystem and libraries being different. Which is why POSIX exists, if you’re looking to write stuff that works across systems.
I couldn’t tell if you were honestly asking for explanations or if all of your complaints sum up to “it’s different and I don’t like that”. Which honestly, fair.
Like, why is bash ancient? (3.2 vs 5)
To avoid GPLv3, zsh is the new default.
Why is there no package manager
Mac App store is the official one, can also install brew, macports, pkgsrc, or nix. Or use language/runtime specific ones like npm, pip, cargo, go.
Why are the utils like ls and friends flag-order-sensitive
They avoid GNU versions of utilities, for similar licencing fears as avoiding modern bash. That said ls . -lah is unhinged, I don’t know any other unix derived ls that supports that.
Why do I have 40 network devices with cryptic names?
Yeah they got some weirdo Apple stuff
Gotta preach for the cult of ZFS. It’s check summing, copy on write, and zraid features are all exactly what you want for data resilience. Plus you get transparent compression, and snapshots that can provide a bit of a stop-gap for your lack of backups.
It will normally soak up any and all memory for buffers and caches, but is meant to quickly free up when it’s needed by an app. Linux already does this on any filesystem with its page cache.
Oh and mounting a ZFS dataset on a new machine is super quick and easy, it stores it’s config on the drives themselves, so you can plug them into a new box and zpool import -af and boom it’s mounted and ready to go.
Didn’t know Doc Martins did Chelsea style boots, that’s sick!
I keep buying and wearing out various no-name cheap boots. One day I’ll get a pair of RM Williams or even Crockett & Jones…
What bash scripts are you writing that you expect to run on both a Mac laptop and a production linux server? You can install the newer bash if that’s what you’re used to, but you’re surely going to run into issues like
ls . -lahfar quicker than differences in bash since 3.2Even on a linux desktop you’re going to have differences from a production server, you’d want to be using something like ansible, or replicating production in a local test environment in a container or VM. Exactly like you have done.
How’d you end up being the only one at your workplace to be given a Mac? Even with a linux VM, being on ARM can cause issues with compatibility.
