Shell environments across Bash and Zsh can behave differently, making common commands fragile due to noclobber, extended globbing, and tricky quoting. This Skill guides you to write cross-shell commands that behave predictably in both shells.
Describe a shell task you want to run and Claude will generate a zsh- and bash-safe command sequence.

To prevent noclobber errors during shell redirection, use safe redirection operators like >| to forcefully overwrite files in both bash and zsh. This ensures predictable file writing behavior across different shell environments without triggering accidental errors.
Globbing behaves differently in zsh compared to bash due to zsh's extended globbing features and distinct pattern matching rules. You can ensure consistent cross-shell behavior by applying proper quoting strategies to prevent unintended pattern expansion.
The best way to write cross-shell scripts is to detect the current shell and apply safe redirection techniques along with consistent quoting rules. This approach avoids common pitfalls from noclobber and extended globbing differences.
To safely handle special characters in shell commands, apply proper quoting strategies to prevent globbing issues. Using appropriate quotes ensures that special characters are interpreted literally rather than triggering pattern matching in bash or zsh.
The >| redirection operator works as a safe redirection technique in both bash and zsh to bypass noclobber settings. It allows you to forcefully overwrite existing files reliably without encountering shell-specific behavior discrepancies.
You need to worry about noclobber settings breaking shell scripts when performing standard file redirection, as the shell will block overwriting existing files. Using portable workarounds like the >| operator ensures your redirection executes reliably.
