If it's invoked through a symlink, e.g. 'osh', then it behaves like that binary. Otherwise, the binary name can be passed as the first argument, e.g.: oil.ovm osh -c 'echo hi'  bin/osh Usage  Usage: osh [OPTION]... SCRIPT [ARG]... osh [OPTION]... -c COMMAND [ARG]... 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  bin/oil Usage  Usage: oil [OPTION]... SCRIPT [ARG]... oil [OPTION]... -c COMMAND [ARG]... bin/oil is the same as bin/osh with a the oil:all option group set. So bin/oil also accepts shell flags. oil -c 'echo hi' oil myscript.oil echo 'echo hi' | oil  bin/osh Usage  Usage: osh [OPTION]... SCRIPT [ARG]... osh [OPTION]... -c COMMAND [ARG]...
