Jexy

Jexy is a Java library to make executing external processes (and optionally read error/output streams) a breeze with a very easy to use API.

Getting started

Jexy can be pulled from maven easily by adding it to Gradle dependencies as follows:

allprojects {
    repositories {
        maven { url 'https://jitpack.io' }
    }
}

dependencies {
    compile 'com.github.vaibhavpandeyvpz:jexy:master-SNAPSHOT'
}

Usage

import com.github.vaibhavpandeyvpz.jexy.ShellProcess;

class EntryPoint {
    
    static int main(String[] args) {
        // E.g. 1, To run a command and just get the **exit code**
        ShellProcess process = new ShellProcess("sh", "-c", "echo 'something' > somefile.txt");
        if (0 == process.execute()) {
            System.out.println("File save successfully.");
        }

        // E.g. 2, To run a command and retrieve the output
        ShellProcess process = new ShellProcess("sh", "-c", "cat somefile.txt");
        ShellResult result = process.execute(true, true);
        if (0 == result.getExitCode()) {
            // General output from process
            List<String> STDOUT = result.getStdOut();
            // Error output from process
            List<String> STDERR = result.getStdErr();
        }

        // E.g. 3, To run multiple commands in one process
        ShellProcess process = new ShellProcess("sh");
        // COMMANDS >>>
        process.add("chmod", "644", "somefile.txt");
        process.add("chown", "-R", "user:group", "/var/www");
        process.add("exit"); // You must exit an interactive process manually
        // <<< COMMANDS
        if (0 == process.execute()) {
            // It all ran interactively in one process
        }
    }
}
