 ## Script Structure
 
-The script uses `set -e` and is sequential with interactive prompts (`read -p`). It writes config files inline using **quoted heredocs** (`cat > ~/.file << 'TAG'`) so variables aren't expanded during write. The tmux toggle uses a `__TMUX_TOGGLE__` placeholder in the zshrc heredoc, replaced via `sed -i ''` after writing — this is the only value that needs post-write substitution.
+The script uses `set -e` and is sequential with interactive prompts (`read -p`). It writes config files inline using **quoted heredocs** (`cat > ~/.file << 'TAG'`) so variables aren't expanded during write. Two placeholders need post-write substitution: `__TMUX_TOGGLE__` in the zshrc and `__CLIPBOARD_CMD__` in the tmux.conf, both replaced via the `sed_inplace` helper.

+**OS detection** uses `uname -s` to set `IS_MACOS`/`IS_LINUX` booleans at the top. macOS uses Homebrew for packages; Linux (Ubuntu/Debian) uses apt, with curl installers for packages not in apt (starship, bun) and a git clone for zsh-completions. The `sed_inplace()` helper wraps `sed -i ''` (BSD) vs `sed -i` (GNU) — it's the only helper function needed.

+# Plan: Add Linux Support to Terminal Setup Scripts
+
+## Context
+
+The scripts currently only work on macOS. Users want to run the same setup on Linux. The approach: detect the OS, use **apt** on Linux (not Homebrew/Linuxbrew) since that's what Linux users expect, and use **Homebrew** on macOS as before. Target: Ubuntu/Debian (apt). The architecture allows adding dnf/pacman later.
+
+Key insight: make the `.zshrc` itself cross-platform by checking which paths exist at runtime — no placeholders needed for plugin paths.

+## Changes: setup-terminal.sh
+
+### 1. Header + OS detection (after `set -e`)
+- Update header comment: "macOS / Linux Terminal Setup"
+- Add OS detection booleans: `IS_MACOS` / `IS_LINUX` via `uname -s`
+
+### 2. Helper function
+- `sed_inplace()` — wraps `sed -i ''` (BSD) vs `sed -i` (GNU). Only helper needed.
+
+### 3. Package installation (Sections 1-2, 4)
+
+**Section 1 — Homebrew (macOS only):**
+```bash
+if $IS_MACOS; then
+  # existing Homebrew install logic unchanged
+fi
+```
+
+**Section 2 — Core packages:**
+```bash
+if $IS_MACOS; then
+  brew install fzf zsh-autosuggestions zsh-syntax-highlighting zsh-completions starship
+  chmod go-w "$(brew --prefix)/share/zsh-completions" "$(brew --prefix)/share"
+else
+  sudo apt update
+  sudo apt install -y zsh fzf zsh-autosuggestions zsh-syntax-highlighting xclip
+  # zsh-completions: clone from GitHub (not in apt)
+  [[ ! -d "$HOME/.zsh/zsh-completions" ]] && \
+    git clone --depth 1 https://github.com/zsh-users/zsh-completions ~/.zsh/zsh-completions
+  # starship: not in apt on 24.04
+  command -v starship &>/dev/null || curl -sS https://starship.rs/install.sh | sh -s -- -y
+fi
+```
+
+**Section 3 — tmux:**
+```bash
+if $IS_MACOS; then brew install tmux; else sudo apt install -y tmux; fi
+```
+
+**Section 4 — Dev tools:**
+```bash
+if $IS_MACOS; then
+  brew install gh bun ripgrep fd zoxide git-delta
+else
+  sudo apt install -y ripgrep fd-find zoxide git-delta
+  # gh: official apt repo
+  if ! command -v gh &>/dev/null; then
+    # (official keyring + repo setup, then sudo apt install gh)
+  fi
+  # bun: official installer
+  command -v bun &>/dev/null || curl -fsSL https://bun.sh/install | bash
+  # fd alias hint (binary is fdfind on Debian/Ubuntu)
+fi
+```
+
+### 4. fzf keybindings (Section 6)
+```bash
+if $IS_MACOS; then
+  yes | $(brew --prefix)/opt/fzf/install --key-bindings --completion --no-update-rc 2>/dev/null || true
+fi
+# On Linux, fzf shell integration is sourced directly in .zshrc from /usr/share/doc/fzf/examples/
+```
+
+### 5. tmux.conf clipboard (Section 8)
+- Use `__CLIPBOARD_CMD__` placeholder for the 6 `pbcopy` instances
+- After writing heredoc, replace with `sed_inplace`:
+  - macOS: `pbcopy`
+  - Linux: `xclip -selection clipboard` (or `xsel`/`wl-copy` if found)
+- Update comment from "macOS clipboard" to "system clipboard"
+
+### 6. .zshrc — make it cross-platform at runtime (Section 9)
+
+**Key idea:** Instead of placeholders, write a .zshrc that detects paths at runtime. This keeps the heredoc readable.
+
+**Homebrew shellenv (line 168):**
+```zsh
+# --- Homebrew (macOS) ---
+[[ -f /opt/homebrew/bin/brew ]] && eval "$(/opt/homebrew/bin/brew shellenv)"
+```
+This silently does nothing on Linux. Clean.
+
+**Completions fpath (line 199):**
+```zsh
+# --- Tab completion ---
+# Homebrew zsh-completions (macOS)
+[[ -d "$(brew --prefix 2>/dev/null)/share/zsh-completions" ]] && FPATH="$(brew --prefix)/share/zsh-completions:$FPATH"
+# Git-cloned zsh-completions (Linux)
+[[ -d "$HOME/.zsh/zsh-completions/src" ]] && fpath=($HOME/.zsh/zsh-completions/src $fpath)
+autoload -Uz compinit && compinit
+```
+
+**Autosuggestions (line 207):**
+```zsh
+# Fish-like autosuggestions (grey ghost text, → to accept)
+for _f in {$(brew --prefix 2>/dev/null),/usr}/share/zsh-autosuggestions/zsh-autosuggestions.zsh; do
+  [[ -f "$_f" ]] && source "$_f" && break
+done
+```
+
+**Syntax highlighting (line 212):**
+```zsh
+for _f in {$(brew --prefix 2>/dev/null),/usr}/share/zsh-syntax-highlighting/zsh-syntax-highlighting.zsh; do
+  [[ -f "$_f" ]] && source "$_f" && break
+done
+```
+
+**fzf (line 215):**
+```zsh
+# fzf fuzzy search (Ctrl+R for history, Ctrl+T for files)
+if [[ -f ~/.fzf.zsh ]]; then
+  source ~/.fzf.zsh
+elif [[ -d /usr/share/doc/fzf/examples ]]; then
+  source /usr/share/doc/fzf/examples/key-bindings.zsh
+  source /usr/share/doc/fzf/examples/completion.zsh
+fi
+```
+
+**Zoxide (line 223):** Already cross-platform (`command -v zoxide`). No change.
+
+**tmux auto-start (line 176):** Add `$DISPLAY` / `$WAYLAND_DISPLAY` checks:
+```zsh
+if [[ "$USE_TMUX" == "true" ]] && command -v tmux &>/dev/null && [[ -z "$TMUX" ]] && \
+   [[ "$TERM_PROGRAM" == "Apple_Terminal" || "$TERM_PROGRAM" == "iTerm.app" || -n "$DISPLAY" || -n "$WAYLAND_DISPLAY" ]]; then
+```
+
+**macOS 26 true color (line 229):** Wrap in `COLORTERM` check (Linux terminals usually set it):
+```zsh
+if [[ -z "$COLORTERM" ]] && [[ "$(sw_vers -productVersion 2>/dev/null)" == 26.* ]]; then
+  export COLORTERM=truecolor
+fi
+```
+
+**fd alias:** Add near other aliases:
+```zsh
+command -v fdfind &>/dev/null && ! command -v fd &>/dev/null && alias fd='fdfind'
+```
+
+**Local binaries:** Add `~/.bun/bin` to PATH for Linux bun install:
+```zsh
+export PATH="$HOME/.local/bin:$HOME/.bun/bin:$PATH"
+```
+
+### 7. sed -i call (line 262)
+- Use `sed_inplace` for `__TMUX_TOGGLE__` replacement (only remaining placeholder)
+- Add `__CLIPBOARD_CMD__` replacement for tmux.conf if tmux was installed
+
+### 8. Font install (Section 11)
+- macOS: `brew install --cask font-monaspice-nerd-font` (unchanged)
+- Linux: download from `github.com/ryanoasis/nerd-fonts/releases` to `~/.local/share/fonts`, run `fc-cache -fv`
+
+### 9. Terminal.app profile (Section 12)
+- Wrap entire section in `if $IS_MACOS` — silently skipped on Linux
+
+### 10. Summary output (Section 13)
+- "Quit Terminal.app (Cmd+Q)" → "Close and reopen your terminal" on Linux
+- Option as Meta key reminder → macOS only
+- "Cmd+D" tmux note → macOS only
+- Font message → "installed to ~/.local/share/fonts" on Linux
+- AI agents: `--cask` → `npm` for claude-code/codex on Linux
+- "another Mac" → "another machine" on Linux
+- Add `chsh -s $(which zsh)` reminder on Linux if shell isn't zsh
+
+---
+
+## Changes: reset-terminal.sh
+
+### 1. OS detection + `sed_inplace` helper (same as setup)
+
+### 2. Minimal .zshrc (Section 1)
+Replace hardcoded `/opt/homebrew` with the same runtime-check pattern:
+```zsh
+[[ -f /opt/homebrew/bin/brew ]] && eval "$(/opt/homebrew/bin/brew shellenv)"
+```
+
+### 3. Terminal.app profile reset (Section 3)
+- Wrap `defaults read/write` block in `if $IS_MACOS`
+
+### 4. Package uninstall (Section 5)
+- macOS: existing brew/cask uninstall (unchanged)
+- Linux: `sudo apt remove` for apt-installed packages, `rm -rf ~/.zsh/zsh-completions`, prompt to remove nerd font from `~/.local/share/fonts`
+
+### 5. Summary text (Section 6)
+- "Cmd+Q" → conditional macOS/Linux text
+
+---
+
+## Changes: README.md
+
+- Header: "one-command macOS terminal setup" → "one-command macOS & Linux terminal setup"
+- Homebrew row: "macOS package manager" → "macOS package manager (Linux uses apt)"
+- tmux clipboard: "macOS clipboard" → "system clipboard"
+- Terminal.app profile section: note "(macOS only)"
+- Nerd Fonts install commands: add Linux alternative
+- "fresh Mac" → "fresh Mac or Linux machine"
+- Roadmap: `- [x] Linux support`
+
+## Changes: AGENTS.md
+
+- "macOS terminal setup script" → "macOS / Linux terminal setup script"
+- Document OS detection and `sed_inplace` helper
+- Note: macOS uses Homebrew, Linux uses apt
+- Note which sections are macOS-only
+
+---
+
+## Verification
+
+1. Read through both scripts checking all conditional blocks
+2. Verify no leftover `__CLIPBOARD_CMD__` placeholders in output files
+3. Verify .zshrc plugin source paths work on both OS (path-exists checks)
+4. macOS: should behave identically to current version
+5. Linux: verify apt install, font download, skipped Terminal.app section, fzf integration paths
