KornShell VS LeechBlock

• 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.

• Customizability
  LeechBlock allows users to customize the blocking rules according to their schedule and needs, including setting time limits, days, and hours for blocking specific websites.
• Simple to Use
  The interface of LeechBlock is user-friendly, allowing even those who are not tech-savvy to easily set up and manage their block lists.
• Multiple Blocking Options
  LeechBlock provides various blocking options including the ability to block websites based on keywords, domains, subdomains, and even wildcards, giving users extensive control over their browsing habits.
• Productivity Focus
  The primary aim of LeechBlock is to enhance productivity by preventing access to distracting websites, which can help users stay focused on their work or study.
• Free to Use
  LeechBlock is available for free, making it an accessible option for anyone looking to improve their online habits without financial barriers.

Possible disadvantages

• Limited Browser Support
  LeechBlock is primarily available as a browser extension and its functionality can be limited depending on the browser used. It may not support all browsers or may have inconsistent performance across different browsers.
• Dependency on Browser
  As a browser extension, LeechBlock only works within the browser in which it is installed. It does not block apps or other browsers, reducing its effectiveness if users switch browsers or use different devices.
• Potential for Workarounds
  Users determined to bypass the restrictions may find ways to disable or circumvent LeechBlock, which can undermine its effectiveness in controlling browsing habits.
• Lack of Advanced Features
  Compared to some paid or more comprehensive web-blocking software, LeechBlock may lack advanced features such as detailed usage reports, cross-device synchronization, or parental controls.
• Learning Curve for Detailed Configuration
  While basic use is straightforward, configuring more complex rules and settings might require a bit of a learning curve, especially for users who want to take full advantage of its customizability.

  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
