KornShell VS WordPress Admin Columns

• 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.

• Customizable Admin Columns
  Allows users to add, remove, and rearrange columns in the WordPress admin panel for posts, pages, users, media, and custom post types, making content management more efficient.
• No Coding Required
  Provides a user-friendly interface that lets administrators customize columns without needing to write PHP or edit theme files, making it accessible to non-developers.
• Supports Custom Fields and Meta Data
  Enables display of custom fields, ACF fields, taxonomies, and other meta data directly in the admin list tables, improving visibility of important information at a glance.
• Improves Workflow Efficiency
  By displaying relevant data directly in admin columns, users can sort, filter, and manage content faster without opening each individual post or page.
• Compatible with Popular Plugins
  Often integrates well with plugins like Advanced Custom Fields (ACF), WooCommerce, and other common WordPress plugins, extending its usefulness across different site types.

• 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
