# JvmOptionsParser.java
2+
3+
Inspired by [InstallCert](https://github.com/escline/InstallCert)
4+
and [/etc/elasticsearch/jvm.options](https://github.com/elastic/elasticsearch/blob/main/distribution/src/config/jvm.options)
5+
6+
## Usage
7+
8+
Need to compile, first:
9+
10+
```
11+
javac --source 1.8 --target 1.8 -d . src/main/java/JvmOptionsParser.java
12+
```
13+
14+
```bash
15+
java JvmOptionsParser <args>
16+
```
17+
18+
> **Note** since Java 11, you can run it directly without compiling it first:
19+
20+
```
21+
java src/main/java/JvmOptionsParser.java <args>
22+
```
23+
24+
## Jar
25+
26+
```bash
27+
ant
28+
29+
java -jar dist/JvmOptionsParser.jar <args>
30+
```
31+
32+
download precompiled jar
33+
34+
```bash
35+
curl -fsSL -O https://github.com/dyrnq/JvmOptionsParser/releases/download/v0.0.1/JvmOptionsParser.jar
36+
37+
java -jar JvmOptionsParser.jar <args>
38+
```
39+
40+
## Args and ENV
41+
42+
need args pass a conf folder or file
43+
44+
- folder eg. `java -jar JvmOptionsParser.jar /etc/es`, then `/etc/es/jvm.options + /etc/es/jvm.options.d/*.options`.
45+
- file eg. `java -jar JvmOptionsParser.jar /etc/es/my.options`, `then /etc/es/my.options + /etc/es/jvm.options.d/*.options`.
46+
- env ES_JAVA_OPTS JAVA_OPTS JAVA_OPTIONS JVM_OPTS JVM_OPTIONS.
47+
48+
