#3Why not fish (friendly interactive shell)?
Not the OP, but I was under the impression that fish de-emphasizes shell scripting/programming and puts more emphasis on the interactive experience.
It feels like bish is trying to make using bash as a programming language tolerable.

#4def printall(files) {
for (f in files) {
print(f);
}
# cwd, ls, and cd are all builtin functions.
dir = cwd();
files = ls();
print("Files in current directory $dir:");
printall(files);
cd("/");
files = ls();
print("Files in root directory:");
printall(files);
Whats wrong with this, much shorter Bash sequence:
echo Files in current directory `pwd`:
ls
cd /
echo Files in root directory:
ls

(OP here). You're right: for simple tasks like listing files or changing directories, you probably don't need bish. I should come up with some better examples where bish wins in readability.

That's what I was going for. Not a replacement for bash the shell, but a language that provides a bit more comfort for programmers while retaining the ability to run on any system your scripts did previously.

I believe the problem comes when trying to do stuff like check to see if a file is in a directory. I'm a ZSH user myself, and my default scripting language is Python for similar reasons to the OP's for inventing Bish. I can't for the life of me figure out the syntax for an if statement, especially for things like checking if files exist. Yes, Bash or Zsh have a shorter syntax for the example, but to do something like this[1] in bash/zsh would be, for me at least, needlessly difficult and painful.

#9Great idea and looks like a good implementation. Are there native hashmaps and arrays? Those are things I like from Powershell.

#10Why?
