shell-function

To create portable shell functions across bash, zsh, and fish, you need environment detection and shell-specific syntax generation. This skill detects your active shell and outputs idiomatic wrapper code with proper quoting and local variables for cross-environment reuse.

The best way to write reusable shell aliases for automation tasks is generating portable, idiomatic code tailored to your current shell. This approach applies safe defaults and clear usage guidance to ensure aliases function correctly across POSIX sh, bash, zsh, and fish environments.

Yes, generating one-liners for POSIX sh is fully supported alongside bash, zsh, and fish. The process detects the active environment and applies shell-specific syntax and safe defaults to ensure the generated one-liners execute correctly within POSIX-compliant environments.

To install generated shell functions into your shell config, follow the guided workflow provided after code generation. This workflow walks you through reviewing the portable code, installing it, and integrating the shell-specific syntax directly into your active environment configuration.

Shell aliases break when switching between zsh and fish because each shell requires specific syntax and quoting rules. Generating portable, idiomatic shell functions with environment detection ensures the output code uses correct local variables and syntax tailored for the active shell.
