### WHY BASH?
|
|
# Ease of installation.
|
|
# No compiling or installing gems, CPAN modules, pip packages, etc.
|
|
# Simple to use and read. Clear syntax and straightforward output interpretation.
|
|
# Built-in power.
|
|
# Pattern matching, line processing, and regular expression support are available natively,
|
|
# no external binaries required.
|
|
# Cross-platform consistency.
|
|
# '/bin/bash' is the default shell on most Linux distributions, ensuring scripts run unmodified across systems.
|
|
# macOS compatibility.
|
|
# Since macOS Catalina (10.15), the default login shell has been zsh, but bash remains available at '/bin/bash'.
|
|
# Windows support.
|
|
# You can use bash via WSL, MSYS2, or Cygwin on Windows systems.
