KornShell VS TouchDevelop

• Compatibility
  KornShell (ksh) maintains backward compatibility with Bourne Shell (sh), making it easy for users familiar with sh to transition without altering their existing scripts substantially.
• Advanced Scripting Features
  ksh offers advanced scripting capabilities such as associative arrays, floating-point arithmetic, and built-in regular expressions, providing more powerful and flexible scripting tools.
• Job Control
  It provides robust job control, allowing users to manage and switch between multiple background tasks and processes easily.
• Interactive Use
  ksh supports features like command aliasing, history manipulation, and inline editing, enhancing its utility in interactive command-line environments.
• Performance
  ksh scripts often execute faster than those written in other shells like csh, due to more efficient resource management and execution mechanisms.

Possible disadvantages

• Complexity
  ksh is more complex compared to simpler shells like sh, making it potentially overwhelming for beginners or those seeking simplicity.
• Portability
  Not all systems come with ksh pre-installed, and differences between ksh88 and ksh93 can lead to portability issues across different Unix-like systems.
• Learning Curve
  Due to its rich feature set, ksh has a steeper learning curve, which could be a barrier for new users unfamiliar with shell scripting.
• Limited Adoption
  Despite its capabilities, ksh is not as widely adopted as other shells like bash or zsh, meaning less community support and fewer resources available.
• Licensing
  ksh is under the Common Public License, which may pose constraints for users or organizations compared to more permissively licensed shells.

• Beginner-Friendly
  TouchDevelop provides a simplified programming environment that is accessible to beginners, making it easier for those with little to no coding experience to start developing applications.
• Cross-Platform Development
  The platform allows users to create applications that can run on multiple operating systems like Windows, iOS, and Android, thus broadening the reach of the applications developed.
• Cloud Integration
  TouchDevelop seamlessly integrates with cloud services, enabling users to store data and access various web services easily within their applications.
• Mobile Friendly
  TouchDevelop can be used on mobile devices, allowing users to develop apps directly on their smartphones or tablets, which enhances portability and convenience.
• Interactive Learning
  The interactive tutorial and help system guide users through the learning process, enhancing their understanding and making it easier to pick up programming concepts.

Possible disadvantages

• Limited Advanced Features
  For more experienced developers, TouchDevelop lacks some advanced features and flexibility offered by more powerful development environments, limiting its usefulness for complex applications.
• Discontinued Support
  TouchDevelop is no longer actively maintained by Microsoft, which means users might encounter issues or lack updates and support in the future.
• Dependence on Internet Connection
  While it offers cloud integration, reliance on internet connectivity for some features can be a drawback in situations where access to the internet is limited or unavailable.
• Platform-Specific Limitations
  Although it is designed for cross-platform compatibility, TouchDevelop may have some limitations or inconsistencies across different operating systems.
• Limited Community and Resources
  As a niche tool with a smaller user base, finding community support, third-party tutorials, or comprehensive resources can be more challenging compared to popular platforms.

• Trying to Set-up android9(ver6) in VirtualBox

  Well now I'm at the point that I see it's calling for the Korn shell, which I'm not directly familiar with, and seemed to stop on the mouse input driver. I'll change my VBox mouse device settings and see what happens from there... Source: over 4 years ago
