> Those who do not understand Unix are condemned to reinvent it, poorly. -- Henry Spencer

I absolutely abhor this quote, I think it's taken out of context.

First of all, it denotes hubris, which I hate.

Secondly, it's totally anti-scientific, it assumes that Unix is some paragon of OS design, the zenith of Computer Science.

I like Unix as much as the next IT guy, but let's cut it out with the cliché quotes. There's plenty of things Unix doesn't do that well (everything is a file, until it isn't; filenames are basically binary blobs, etc.: https://dwheeler.com/essays/fixing-unix-linux-filenames.html).

Plus your comment is just silly, whoever implemented this obviously knew about Unix shells... It takes knowledge of Unix shells to implement another Unix-y shell.
