MAIN_NAME [ARG]... oil.ovm behaves like busybox. If it's invoked through a symlink, e.g. 'osh', then it behaves like that binary.

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.
