rc - a shell features and specs

  • Simplicity
    rc is designed to be a simpler alternative to other complex shells, offering a more streamlined set of features that can be easier for users to learn and use.
  • Consistent Syntax
    rc uses a consistent and clean syntax, which can help reduce common scripting errors and improve readability.
  • Minimalistic Design
    With fewer built-in features, rc allows users to focus on essential commands without the clutter of unnecessary options.

Possible disadvantages of rc - a shell

  • Limited Features
    Due to its minimalist design, rc lacks some of the advanced features and functionalities found in more complex shells like bash or zsh.
  • Community and Support
    rc may have a smaller community and less available documentation, leading to potential challenges in finding support or resources.
  • Less Compatibility
    Some scripts or tools designed for more common shells might not work seamlessly in rc without modifications.

KornShell features and specs

  • 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 of KornShell

  • 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.

  • 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 3 years ago
