Fish shell + Starship prompt setup on Nobara FC43

Summary

Migrated interactive shell from zsh to fish on Nobara FC43 (Linux 6.18 kernel). Full setup for fish + Starship with bash-for-scripts hybrid strategy.

Installation

• Fish installed via dnf
• Set as default login shell: chsh -s /usr/bin/fish
• Starship installed via dnf (starship package in nobara-updates repo)

Fish config (~/.config/fish/config.fish)

if status is-interactive
    set -x SHELL /bin/bash   # Keep Claude Code and scripts on bash
    starship init fish | source
end

Key detail: set -x SHELL /bin/bash is set inside config.fish so Claude Code's Bash tool, shebang scripts, and any tool that respects $SHELL continue using bash — not fish (which is POSIX-incompatible).

Starship config (~/.config/starship.toml)

• AWS module disabled (not used)
• git_commit disabled (too noisy)
• git_metrics enabled with only_nonzero_diffs = false (always shows +N -N stats)

Compatibility Notes

• Fish is POSIX-incompatible: no export, different variable syntax, different conditionals
• Scripts with #!/bin/bash shebangs are completely unaffected
• Claude Code shell execution unaffected due to the SHELL override
• Starship works identically across fish, zsh, and bash — config is shell-agnostic
