About:
checkbashisms is a tool designed to verify that shell scripts do not contain bash-specific syntax, ensuring they adhere to POSIX standards. It scans scripts for non-portable constructs like specific bashisms and flags them for review. This helps developers create portable scripts that can run on any POSIX-compliant shell, reducing compatibility issues across different Unix-like systems.
Key Features:
  • Detects common bashisms in shell scripts
  • Supports checking scripts with various shell interpreters
  • Provides detailed error messages for non-portable code
  • Integrates easily into CI/CD pipelines for automated checks
Use Cases:
  • Validating shell scripts for cross-platform compatibility
  • Auditing legacy scripts to ensure portability
  • Enforcing coding standards in team projects
Alternatives:
  • shellcheck – shellcheck performs broader static analysis for bugs and style, while checkbashisms focuses specifically on bash vs. POSIX portability.
