Clean Agnoster Prompt + Hidden tmux Status Bar (Mac / zsh)

Goal

• Use Oh My Zsh with the agnoster theme.
• Show only the current folder in the blue segment (not the full path).
• Keep the left git segment: ▶ main ±.
• Hide:
  • user@host (e.g. rupesh@Rupeshs-MacBook-Pro)
  • right-side git:(main*).
• Put the cursor on the next line with a nice arrow.
• Use tmux splits, but hide the green tmux status bar globally.

---

1. zsh / agnoster configuration

1.1 Set theme to agnoster

In ~/.zshrc:

ZSH_THEME="agnoster"

(make sure other themes like fwalch, refined, etc. are not active)

---

1.2 Final agnoster tweaks

Add this block at the very bottom of ~/.zshrc:

# --- Rupesh final agnoster tweaks ---

# 1) Hide user@host segment (rupesh@Rupeshs-MacBook-Pro)
prompt_context() { :; }

# 2) Show only current folder, white text on blue
prompt_dir() {
  local dir="%1~"           # %1~ = just the last path segment
  prompt_segment blue white "$dir"
}

# 3) Remove everything on the right side (e.g. git:(main*))
RPROMPT=''

# 4) Put the cursor on the next line with a smart arrow
PROMPT+='
%F{39}➜%f '

Reload zsh:

source ~/.zshrc

1.3 Result

Prompt now looks like:

demo-1-inspect-brokers ▶ main ±
➜ 

• Blue segment: current folder only.
• Yellow segment: git branch + dirty marker.
• No hostname.
• No right-side git:(main*).
• Cursor on its own line with an arrow.

2. tmux configuration (hide green bar for all sessions)

2.1 Create or edit ~/.tmux.conf

Open:

code ~/.tmux.conf

Put this inside:

# Hide the tmux status bar globally
set -g status off

Save the file.

2.2 Apply to current tmux session (optional)

If you’re inside tmux already:

tmux source-file ~/.tmux.conf

Or just start a new session:

tmux

2.3 Result

• No green status bar at the bottom.

• Clean screen with only your agnoster prompt.

• You can still use tmux splits:

  • Horizontal split: Ctrl + b then ".
  • Vertical split: Ctrl + b then %.
  • Move between panes: Ctrl + b then arrow keys.

---

Final State

You now have:

demo-1-inspect-brokers ▶ main ±
➜ _

in each tmux pane, with:

• Clean agnoster theme.
• Short folder name.
• Git info on the left only.
• No tmux status bar.
• Full-width line to type commands.
