About:
Bash is the GNU Project's shell, designed as a superset of the Bourne shell (sh). It provides interactive command-line editing, job control, and shell functions while supporting the POSIX standard. It is the default login shell for most Linux distributions and macOS.
Key Features:
  • Interactive command-line editing and history
  • Job control for process management
  • Advanced scripting with arrays and integer arithmetic
  • POSIX-compliant with backward compatibility to sh
Use Cases:
  • Interactive command-line usage as a system login shell
  • Writing system administration and build automation scripts
  • Automating tasks via shell scripts and pipelines
Alternatives:
  • zsh – Adds advanced completion and theming; often preferred for interactive use
  • fish – Focuses on user-friendly interactivity with auto-suggestions and syntax highlighting
  • dash – Lightweight, fast POSIX shell optimized for script execution
