- **-m** / **--multi** \<dir\>

Available options for specifying values of 'external' variables: Provide the value as a string:

- **-V** / **--ext-str** \<var\>\[=\<val\>\]

  If \<val\> is omitted, get from environment var \<var\>

**--ext-str-file** \<var\>=\<file\> Read the string from the file

### Provide a value as Jsonnet code:

- **--ext-code** \<var\>\[=\<code\>\]

  If \<code\> is omitted, get from environment var \<var\>

**--ext-code-file** \<var\>=\<file\> Read the code from the file

Available options for specifying values of 'top-level arguments': Provide the value as a string:

- **-A** / **--tla-str** \<var\>\[=\<val\>\]

  If \<val\> is omitted, get from environment var \<var\>

**--tla-str-file** \<var\>=\<file\> Read the string from the file

### Provide a value as Jsonnet code:

- **--tla-code** \<var\>\[=\<code\>\]

  If \<code\> is omitted, get from environment var \<var\>

**--tla-code-file** \<var\>=\<file\> Read the code from the file

Environment variables: JSONNET\_PATH is a colon (semicolon on Windows) separated list of directories added in reverse order before the paths specified by **--jpath** (i.e. left-most wins) E.g. JSONNET\_PATH=a:b jsonnet **-J** c **-J** d is equivalent to: JSONNET\_PATH=d:c:a:b jsonnet jsonnet **-J** b **-J** a **-J** c **-J** d

In all cases: \<filename\> can be - (stdin) Multichar options are expanded e.g. **-abc** becomes **-a** **-b** **-c**. The **--** option suppresses option processing for subsequent arguments. Note that since filenames and jsonnet programs can begin with -, it is advised to use **--** if the argument is unknown, e.g. jsonnet **--** "$FILENAME".
