  • Performance Overhead
    Loading many plugins and customizations can introduce a performance hit, making zsh slower to start compared to more lightweight shells.
  • Resource Consumption
    zsh, particularly with extensive customizations and plugins, can consume more system resources (memory and CPU) than simpler shells like bash.
  • Inconsistent Behavior with Legacy Scripts
    While zsh is largely compatible with bash, certain edge cases and legacy scripts might exhibit inconsistent behavior, potentially necessitating script rewrites or adjustments.

  • My developer workflow using WSL, tmux and Neovim
    Ubuntu by default comes with the bash shell. Bash is great but I personally find it harder to customize. That is why I use Z shell, more commonly known as zsh. To manage my zsh configuration, I use Oh My Zsh. It has a huge community and makes it trivial to install and use plugins. - Source: dev.to / almost 3 years ago
