Bash is a shell. A bad shell. Korn is a good shell.

It's not meant to be a real language. It's meant to be a shell. Here, let me back that up and reverse it for you.

<JAVA> public Set<String> listFilesUsingJavaIO(String dir) { return Stream.of(new File(dir).listFiles()) .filter(file -> !file.isDirectory()) .map(File::getName) .collect(Collectors.toSet()); } //I'm not handling errors, and this doesn't actually print anything, it just lets me try to.

<SHELL> ls

Shell is meant to be a common way to do common tasks on commandline, and make a little script if you want to save that and run it again. I can do little things in a shell one-liner quick, that would take a page of python or perl.

I put up with my sports car because there's no better alternative. It doesn't mean I should put up with a sports car for transporting my piano, just that I must put up with it at least to the point where the sports car can transport me to the car that transports a piano.
