Tmux Command

tech tmux commandprompting

Prefix lu bukan Ctrl+b default. Di ~/.tmux.conf prefix diganti jadi Ctrl+a.

Di note ini: prefix = Ctrl+a.

Mental Model

tmux server
  └── session   (main, catastrophy, work, armagedon, aquarium)
        └── window
              └── pane

• Session = workspace yang hidup meski terminal ditutup
• Window = tab di dalam session
• Pane = split di dalam window

---

Session

# List session
tmux ls
tmux list-sessions
 
# Buat session baru (langsung masuk)
tmux new -s nama-session
 
# Buat session di background, belum attach
tmux new -s nama-session -d
 
# Attach
tmux attach -t nama-session
tmux a -t nama-session
 
# Attach session terakhir
tmux attach
tmux a
 
# Cek session ada atau tidak
tmux has-session -t main
 
# Rename session (dari luar)
tmux rename-session -t lama baru
 
# Detach (dari dalam tmux) — session tetap hidup
# prefix + d
 
# Kill satu session
tmux kill-session -t nama-session
 
# Kill semua session + server
tmux kill-server

Dari dalam tmux:

Keys	Aksi
prefix d	Detach
prefix s	Pilih session (list interaktif)
prefix $	Rename session
prefix ( / )	Session sebelumnya / berikutnya

Setup lu: buka terminal lokal (bukan SSH) otomatis attach ke session main. Kalau main belum ada, .bashrc bikin layout 4 pane (btop kiri, neofetch kanan bawah, 2 pane kerja).

# Reset layout main dari nol
tmux kill-session -t main
# lalu buka terminal baru

---

Window

Keys	Aksi
prefix c	Window baru
prefix n / p	Window berikutnya / sebelumnya
prefix 0–9	Lompat ke window by number
prefix ,	Rename window
prefix &	Kill window (konfirmasi)
prefix w	List window

# Dari luar
tmux new-window -t main -n logs
tmux rename-window -t main:0 backend
tmux kill-window -t main:logs
tmux list-windows -t main

---

Pane — custom lu, bukan default tmux

Default tmux: prefix x = kill pane. Di config lu itu di-unbind.

prefix x = split atas-bawah. Close pane = prefix q.

Split

Keys	Aksi
prefix v	Split kiri-kanan 50-50
prefix x	Split atas-bawah 50-50
prefix V	Split kiri-kanan, pane baru 30%
prefix X	Split atas-bawah, pane baru 30%
prefix Ctrl+v	Split kiri-kanan, pane baru 40%
prefix Ctrl+x	Split atas-bawah, pane baru 40%

Split ikut directory pane aktif (#{pane_current_path}).

# Dari command (bukan keybind)
tmux split-window -h          # kiri-kanan
tmux split-window -v          # atas-bawah
tmux split-window -h -p 30    # pane baru 30%

Navigasi & resize

Keys	Aksi
prefix h j k l	Pindah pane (vim)
klik mouse	Pilih pane
prefix H J K L	Resize 5 cell (bisa ditahan, -r)
prefix =	Layout tiled (rata)
prefix z	Zoom pane (fullscreen / balik)
prefix { / }	Tukar posisi pane
prefix q	Kill pane (tanpa konfirmasi)
prefix !	Pecah pane jadi window baru

Mouse on: drag border pane buat resize.

---

Copy / paste (config lu)

Mouse on + vi copy mode. Drag highlight → langsung ke clipboard via xclip.

Keys	Aksi
drag mouse	Copy + keluar copy-mode
prefix [	Masuk copy-mode manual
v	Mulai seleksi (di copy-mode)
C-v	Rectangle select
y atau Enter	Copy ke clipboard, keluar mode
prefix ]	Paste buffer tmux

Di copy-mode navigasi vim: h j k l.

---

Config & reload

File: ~/.tmux.conf

Keys	Aksi
prefix r	Reload ~/.tmux.conf
prefix R	Jalankan preset layout ~/.tmux-preset-layout.sh

tmux source-file ~/.tmux.conf

prefix R (dari dalam tmux) reset window jadi:

• kiri ~40% → btop
• kanan split 50-50, fokus kanan atas

Status bar mati (set -g status off). List session/window pakai prefix s / w atau tmux ls.

Plugin: tmux-resurrect (~/.tmux/plugins/tmux-resurrect). Restore session setelah reboot:

Keys (default plugin)	Aksi
prefix Ctrl+s	Save
prefix Ctrl+r	Restore

---

Layout & alias di mesin lu

Alias / script	Session	Isi
auto .bashrc	main	4 pane: btop kiri, kerja, neofetch
catastrophy	catastrophy	~/.tmux-catastrophy.sh — kill session lama, 4 pane, btop kiri lebar 100
armagedon	armagedon	~/.tmux-armagedon.sh — 2 pane kiri-kanan
aqua	aquarium	asciiquarium
~/.tmux-layouts.sh	work	4 pane + htop kiri bawah (auto-start ini di-comment di bashrc)
~/.tmux-preset-layout.sh	(window aktif)	prefix R — 3 pane + btop

catastrophy
armagedon
aqua

catastrophy / armagedon / ~/.tmux-layouts.sh kill session namanya dulu kalau sudah ada, lalu bikin ulang.

# Layout work manual (bashrc auto-nya lagi off)
bash ~/.tmux-layouts.sh

Troubleshooting cepat

# Session zombie / layout kacau
tmux kill-session -t main
tmux kill-server
 
# Nested tmux (SSH ke mesin yang juga auto-tmux)
# bashrc lu skip auto-start kalau $SSH_TTY terisi
# prefix remote vs local: local = Ctrl+a
 
# Clipboard drag-select ga ke Ctrl+V
sudo apt install xclip
# Wayland:
sudo apt install wl-clipboard
