I believe it's been posted here before, but I also use this for reference whenever I forget the syntax to something, or know there must be a better way than what I am doing. https://github.com/dylanaraps/pure-bash-bible

I'd say check out the work of William Shotts at https://linuxcommand.org/ His book, "The Linux Command Line" is free for downloading, and there are lots of references to style guides, good practices, and bash templates in the book. There is also a shorter, HTML version at the same site: https://linuxcommand.org/lc3_learning_the_shell.php I'm trying to get a little proficiency in all this, and just yesterday I went through the "Further Reading" sections at the end of each chapter, and captured all the likely URLs for further investigation. One that looks really good is Dylan Araps' "Pure Bash Bible" ( See https://github.com/dylanaraps/pure-bash-bible ) Confession: I found a PDF copy at Libgen, but don't tell anyone. This and the Shotts book have also been thoroughly discussed on Hacker News in the past. (I.e., search on the two titles and

Also incredibly cool project from the author is the Pure Bash Bible: https://github.com/dylanaraps/pure-bash-bible.

nice thanks for sharing! https://github.com/dylanaraps/pure-bash-bible >The goal of this book is to document commonly-known and lesser-known methods of doing various tasks using only built-in bash features. Using the snippets from this bible can help remove unneeded dependencies from scripts and in most cases make them faster.

For a pretty good example of a readable/fun program written in bash, the KISS package manager stands out: https://github.com/kisslinux/kiss/blob/master/kiss Neofetch is also written in bash: https://github.com/dylanaraps/neofetch/blob/master/neofetch For my own work, I once wrote a functional file system based irc client in ~50 lines of bash: https://github.com/retrohacker/irc-sh/blob/master/main.sh To learn bash: * https://tldp.org/LDP/abs/html/ * https://github.com/dylanaraps/pure-bash-bible

This pairs extremely well with dylan's Pure Bash/sh Bible [1], both, combined with admittedly way too many hours browsing random people's dotfiles can exponentially increase your skills with shells scripting. Some tips of my own: Adding `2>/dev/null` or `>/dev/null 2>&1`after most commands with expected or just plain useless output can make writing headless scripts very easy, it also comes in very handy when trying to shut up some basic utilities. A handy function: execute() { pkill -x "$1" { sleep 0.1 "$@" & } } >/dev/null 2>&1 `set --` before running a command can be used to remove all excess whitespace (making parsing dead easy). And last but not least always using printf instead of echo makes your scripts 1000x cooler :) 0. https://github.com/dylanaraps/pure-sh-bible 1. https://github.com/dylanaraps/pure-bash-bible

Actually one more thing I realized about this idea that would be wild... Since re2c itself is written in C, it can be easily compiled to wasm (even if it has a few gotos). So then you get an engine that can compile user patterns at runtime, rather than having it be an offline process. (I don't really think there is that much difference in constraints between the offline and online processes, as some of have suggested. For example I observed that re2c compile time is linear with respect # constants strings in a large range in that benchmark.) I have been thinking of embedding wasm in Oil, mainly to do reasonably fast string transformations. Because one goal of Oil is to provide an alternative to extremely tortured string transformation syntax like: https://github.com/dylanaraps/pure-bash-bible And Oil has the eggex language, that compil
