- Initialize a simple Java class:
`jbang init {{path/to/file.java}}`
- 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}}`
