KornShell VS Online timer

• 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.

• Accessibility
  Online timers can be accessed from any device with an internet connection, making them convenient for users who need a timer while on the go or using different devices.
• User-friendliness
  Many online timers are designed to be simple and intuitive, allowing users to easily set and start timers without needing to download or install software.
• Cost-effective
  Most online timer applications are free to use, eliminating the need for purchasing standalone timer hardware or software.
• Versatility
  Online timers usually offer multiple features such as stopwatches, countdowns, and alarms, providing flexibility for various timing needs.

Possible disadvantages

• Internet Dependence
  Since online timers require an internet connection, they are not functional in the absence of connectivity, limiting their usability in offline scenarios.
• Privacy Concerns
  Using online services may involve data privacy issues, where user data could be accessed or tracked by third parties without the user's consent.
• Advertisement Interruptions
  Free online timer platforms often include advertisements, which can be distracting or disruptive to the user experience.
• Limited Customization
  Some online timers may not offer the same level of customization or advanced features as specialized timer software or hardware.

  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
