Fish config.fish SHELL override

Configuration

~/dotfiles/fish/config.fish contains: set -x SHELL /bin/bash

Rationale

This is intentional. Fish is the interactive shell (set via chsh to /usr/bin/fish), but $SHELL is overridden to bash so scripting tools, agents, and automated processes use bash as expected. Many tools check $SHELL to determine which shell to invoke for scripts.

Environment

  • Fish 4.2.0
  • Starship prompt
  • OS: Nobara Linux (Fedora-based)
  • Interactive shell: /usr/bin/fish
  • Scripting shell: /bin/bash (via $SHELL override)

Key Insight

$SHELL = the user's preferred scripting shell (bash), not the running interactive shell (fish). This separation avoids compatibility issues with tools that assume a POSIX shell.
