Seeing this release makes me cringe. I've used Bash as an interactive shell for decades but really I'm sick and tired of it. As a scripting language, I loathe it and really don't understand its purpose. I always write shell scripts in POSIX shell for portability reasons. Most of the time I don't need to use any of Bash's features. In cases where advanced features are needed and portability is not a concern, there are…

zsh has much better tab completion, you should check it out

I read that often but I don't understand how it can be true. Bash (and I suppose zsh's) tab-completion is programmable so you can make it do whatever you want to.

Zsh, especially with an addon package like oh-my-zsh isn't just programmable but is actually programmed. Like, it just works, near magically - for instance make looks for the Makefile in the current dir and actually scrapes the targets from it.

Experimenting is not the only way to quantify risk. You can also e.g. have several highly paid lawyers look over the text of the license, and see what each of them had to say. The big players in the industry did just that, and there appears to be a remarkable consensus on it.

The remarkable consensus behind IBM's purchase of Red Hat, you mean? Seems like their highly paid lawyers were down with it. Again, it's just stunning the extent to which this FUD hasn't changed at all over a quarter century.

The GPLv3 was intentionally designed to create the risk that Apple and others are trying to avoid. IBM doesn't have that risk because they don't sell hardware or software packages, they sell expensive service contracts.

I recently switched to fish and was quite happy with how little effort it took: chsh, use fish_config to pick a prompt with Git status, and that's it.

zsh completion supports menus, typo correction, caching...

The choice of python as your shell would surely be as arbitrary as bash? There is a long history of alternative shells csh, tcsh, zsh, fish, etc. All with various level of abstraction and various amounts of "programming language type constructs" (for lack of a better term). At the end of the day, long arguments have been had over which is the better shell. It's all just personal preference. Hence it can be set in /et…

My point wasn't about python, just an example of how a shell around python, made only for python function calls, would be a useless abstraction.

Something like IPython, amirite? XD

AFAIK Bash does that by default too (at least it's been the case on my Debian setups for years). It also works with git for example, not just with its subcommands but also with your commits, tags, branches, remotes, etc.

Many Debian packages comes with a completion script for Bash so you get it when you install them :).

Sure. But iOS doesn't have Bash (I don't think, even if it does: Then just ship GPLv2 Bash on iOS, and modern Bash on macOS where users might actually care). The GPLv3 of Bash doesn't infect the shared kernel or libraries between iOS and macOS, it's just the `/bin/sh` program. It's easy enough to check if it's being included in iOS. "The reason we can't ship modern Bash on macOS is that we're concerned we might accid…

Apple is pretty firm on no GPLv3 because accidentally shipping it on iOS can be pretty dangerous for them. Whether you agree with the decision to just not ship GPLv3 software (I don’t), I can understand apples concerns regarding GPLv3. Furthermore, it wouldn’t surprise me if iOS had bash support even for just debug builds and Apple either had to worry about testing, building and maintaining two version of bash and st…

Accidental shipping of IP which a company do not own is a constant risk. Companies sometimes accidental ship proprietary software, copyrighted images, copyrighted text, patented techniques, trademarked names, trademarked images, and more.

A Swedish copyright lobby organization committed copyright infringement on their own website. Bethesda game company had a trademark dispute with the developers of Minecraft. Apple and Samsung are constantly in patent war with each other. There is an almost unlimited number of cases where one company sue an other for contract and license disputes.

Shipping software is pretty dangerous, and there is no data to show that shipping GPLv3 licensed software is more likely to cause accidental infringement of someones IP than other licensed software.

Any recommended reading for Bash? I'm somewhat new to it and it's interesting ways of getting things done. I've used it minimally in the past, but have found myself writing a 100> LOC script, which I can't help but feel I'm likely over-complicating certain bits and pieces.

From the google Shell Style Guide: "If you are writing a script that is more than 100 lines long, you should probably be writing it in Python instead. " https://google.github.io/styleguide/shell.xml

That guide is really useful for making scripts more readable.
