While this is interesting I see doing anything but launching programs with simple text-substituted arguments as too much for bash or sh. Run shellcheck on some of your own code, or the code of even a simple project to see how hard it is to really use bash. Why I think people gravitate towards it is because languages such as python add too much pomp to launching a shell process. A language like perl is usually easier…
Yes, Python is the Cobol of script languages.
I have a personal dislike for regexes and non human readable code, it gives maintenance headache. It's why I avoid shell scripts as much as possible. The first example is not human readable, if the name of the function is a lie, I have no idea what this piece of code do : trim_string() { : "${1#"${1%%[![:space:]]*}"}" : "${_%"${_##*[![:space:]]}"}" printf '%s\n' "$_" }
Hello, I'm the author of the Pure Bash Bible. Happy to answer any questions you may have. Here's an example of what bash is capable of: https://github.com/dylanaraps/fff/ (a TUI file manager written in bash)!

I'll look into also putting the book on Amazon or another "ebook" website. I chose leanpub as it _is_ for books like this but if it does cause issues for people I'll explore my options on other platforms. Thanks for letting me know and apologies for the inconvenience.
It's more an annoyance than really a problem and stick with them rather than Amazon. Leanpub looks like a nice enough bunch and you, as the author, receive most of the proceeds. I'm probably anyway the exception nowadays not being able to access private email remotely. But what you may point out to them is that it may be worthwhile to think through their checkout process. Also for their own benefit and the benefit of…

I have inherited about 4K LOC Bash, which mostly works as advertised. No one wants to touch it! suggestions ?

Just because you seem to be unfamiliar with bash doesn’t mean it’s unreadable. Almost any language will look cryptic if you don’t know it. That function is mostly just parameter expansion and very common in most bash scripts. I bet if you read the manual you would easily be able to figure it out. You just have to learn the language.
Just yesterday I was struck by the difference between if [[ ]]; and if [ ];
I didn't even bother grokking the difference in the end. I simply found something that worked and moved on with my day.

String munging in Python is so much objectively easier to read than bash. I would say that it's because it is similar to a lot of the more popular languages than the sort of cryptic parameter substitution bash provides. And if that makes it easier to maintain some automation, then its worth the effort just to use Python IMO.
