Linux Software Guide

This document provides a list of useful software for Linux, along with installation notes and usage instructions.

Default Software (Core Utilities)

These tools are typically available in a standard Linux installation.

  • update-alternatives: Manages multiple versions of the same software.
    Useful for switching between different versions of tools like Java, Python, etc.

    • General Workflow:
      1. Install the required software versions.
      2. Add each version to update-alternatives.
      3. Configure which version to use.
      4. Test the setup.

    • Example: Managing Multiple JDKs

      1. Install JDKs

         sudo apt update
 sudo apt install openjdk-8-jdk -y
 sudo apt install openjdk-17-jdk -y

      2. Add alternatives for java and related commands
        (Last number = priority)

         # Syntax:
 # sudo update-alternatives --install <link> <name> <path> <priority>

 sudo update-alternatives --install /usr/bin/java java /usr/lib/jvm/java-8-openjdk-amd64/bin/java 800
 sudo update-alternatives --install /usr/bin/java java /usr/lib/jvm/java-17-openjdk-amd64/bin/java 1700

 sudo update-alternatives --install /usr/bin/javac javac /usr/lib/jvm/java-8-openjdk-amd64/bin/javac 800
 sudo update-alternatives --install /usr/bin/javac javac /usr/lib/jvm/java-17-openjdk-amd64/bin/javac 1700

      3. Configure desired version

         sudo update-alternatives --config java
 sudo update-alternatives --config javac

      4. Verify installation

         java -version
 javac -version
