• Initialize a simple Java class:

• Initialize a Java class (useful for scripting):

jbang init --template=cli path/to/file.java

• Use jshell to explore and use a script and any dependencies in a REPL editor:

jbang run --interactive

• Setup a temporary project to edit a script in an IDE:

jbang edit --open=codium|code|eclipse|idea|netbeans|gitpod path/to/script.java

• Run a Java code snippet (Java 9 and later):

echo 'Files.list(Paths.get("/etc")).forEach(System.out::println);' | jbang -

• Run command-line application:

jbang path/to/file.java command arg1 arg2 ...

• Install a script on the user’s $PATH:

jbang app install --name command_name path/to/script.java

• Install a specific version of JDK to be used with jbang:

jbang jdk install version
