Bash-like scripting in shells is prevalent in operating systems but I don’t understand why, when it doesn’t have the syntax to make programming easy like other languages. What features does bash have that make it so suitable for shells? Why even new operating systems like Redox OS choose a very similar syntax over a completely different programming language?
I personally wouldn’t, because the Unix philosophy should still apply. If you need 50k lines of bash to do something that a collection of existing command line tools already can do, you may need to re-evaluate your needs.
As @[email protected] said here, POSIX compliance is extremely important. Much of the “real world” infrastructure is still UNIX based, especially in finance. It isn’t easy to replace those systems at all, especially a legacy codebase that literally the entire world runs on. COBOL and Fortran applications in banking are still being updated today, despite efforts to modernise systems because they just work and the code is pretty much hardened at this point.
As always, in every industry, there is a “right tool” for the job. The great thing about the Unix philosophy is, if correctly applied across your stack, it doesn’t matter what language you write the tools in. Your bash script is only going to be forwarding that output to something that is suited to handle it. This person sped up their python application by using Rust for one set of functions.
