# Decision: fish config.fish exports SHELL=/bin/bash for tool compatibility
|
|
|
|
## Decision
|
|
`~/.config/fish/config.fish` has `set -x SHELL /bin/bash` on line 1.
|
|
|
|
## Rationale
|
|
Tools that spawn subshells based on `$SHELL` (tmux panes, editors like Neovim, some scripts) will use bash rather than fish. Fish is the interactive shell for Cal's terminal experience, but bash remains the scripting/subshell language. This avoids breakage in tools that assume POSIX-ish shell behaviour when they read `$SHELL`.
|
|
|
|
## Scope
|
|
- Fish is the **interactive** login shell (set via `chsh`)
|
|
- Bash is the **subshell/scripting** shell (exported via `$SHELL`)
|
|
- Claude Code is **unaffected** — it spawns its own internal bash regardless of the user's `$SHELL`
|
|
|
|
## Do Not Change
|
|
Do not update this line to `/usr/bin/fish`. If tooling issues arise with bash subshells, investigate the specific tool rather than removing this override.
