Shellharden is a Rust CLI tool that syntax-highlights bash scripts and semi-automatically rewrites them to ShellCheck conformance, mainly by fixing quoting. It can display suggested changes with colored diff-like highlighting or apply them via a --transform mode.

Use cases

• fix unquoted variable expansions in bash scripts
• highlight bash syntax in the terminal
• automatically apply ShellCheck-style quoting fixes
• audit shell scripts for unsafe quoting
• rewrite legacy shell scripts to be safer

When to choose

• you want to automatically fix quoting issues that ShellCheck only reports
• you need terminal syntax highlighting for bash with suggested corrections
• you maintain many shell scripts and want semi-automated hardening

When to avoid

• you need full ShellCheck lint coverage rather than quoting-focused fixes
• your scripts intentionally depend on unquoted word-splitting behavior
• you need linting for POSIX sh or other shells beyond bash
