~~~ oils-usage ~~~

bin/oils-for-unix is an executable that contains OSH, YSH, and more.

Usage: oils-for-unix MAIN_NAME ARG*
       MAIN_NAME ARG*

It behaves like busybox.  The command name can be passed as the first argument:

    oils-for-unix ysh -c 'echo hi'

More commonly, it's invoked through a symlink like 'ysh', which causes it to
behave like that command:

    ysh -c 'echo hi'

Oils 0.26.0		https://oils.pub/

~~~ osh-usage ~~~

bin/osh is compatible with POSIX shell, bash, and other shells.

Usage: osh FLAG* SCRIPT ARG*
       osh FLAG* -c COMMAND ARG*
       osh FLAG*

The command line accepted by `bin/osh` is compatible with /bin/sh and bash.

    osh -c 'echo hi'
    osh myscript.sh
    echo 'echo hi' | osh

It also has a few enhancements:

    osh -n -c 'hello'                    # pretty-print the AST
    osh --ast-format text -n -c 'hello'  # print it full

osh accepts POSIX sh flags, with these additions:

    -n             parse the program but don't execute it.  Print the AST.
    --ast-format   what format the AST should be in
