[Linux] tmux

---

🔹 Step 1: Start a New tmux Session

In your terminal, run:

tmux

🔹 This starts a new tmux session.

---

🔹 Step 2: Run GPU-Burn in the First Pane

Run:

./gpu_burn 60

🔹 This will start GPU stress testing in the current terminal.

---

🔹 Step 3: Split the Terminal (Horizontally or Vertically)

Option 1: Split Horizontally (Top-Bottom)

Press:

Ctrl + B, then "

🔹 This will split the terminal into two panes, one on top and one on the bottom.

Option 2: Split Vertically (Left-Right)

Press:

Ctrl + B, then %

🔹 This will split the terminal into two vertical panes.

---

🔹 Step 4: Switch to the New Pane

After splitting, move to the new pane using:

Ctrl + B, then →

(Use ← or → to switch between panes.)

You can save and restore tmux sessions so you don’t lose your progress after rebooting or logging out.

💾 Save & Restore a tmux Session

1️⃣ Save a Session (Detach Without Closing)

• If you’re inside a tmux session, press:

  cssCopyEditCtrl + B, then D

  This detaches the session but keeps it running in the background.

• To list active sessions:

  tmux list-sessions

  Example output:

  0: 1 windows (attached)
  1: 2 windows (detached)

---

2️⃣ Restore a Saved Session

• Reattach to your last session:

  tmux attach-session -t 0

  (Replace 0 with your session ID from tmux list-sessions.)

• Reattach to the most recent session:

  tmux attach

---

3️⃣ Auto-Restore tmux Sessions After Reboot

By default, tmux does not persist sessions across reboots, but you can fix this.

Option 1: Use tmux-resurrect Plugin (Best Option)

• Install tmux plugin manager:

  bashCopyEditgit clone https://github.com/tmux-plugins/tpm ~/.tmux/plugins/tpm

• Add this to ~/.tmux.conf:

  kotlinCopyEditset -g @plugin 'tmux-plugins/tmux-resurrect'

• Reload tmux:

  bashCopyEdittmux source ~/.tmux.conf

• Save a session anytime:

  cssCopyEditCtrl + B, then Ctrl + S

• Restore after reboot:

  cssCopyEditCtrl + B, then Ctrl + R

Option 2: Use tmuxinator (For Automatic Start)

1. Install:

   bashCopyEditsudo apt install tmuxinator

2. Create a config:

   bashCopyEdittmuxinator new mysession

3. Edit the config (~/.config/tmuxinator/mysession.yml) and define your setup.

4. Start tmux with:

   bashCopyEdittmuxinator start mysession

Option 3: Manually Save & Restore Sessions

If you don’t want plugins, you can log your session names and reattach manually:

bashCopyEdittmux list-sessions > ~/.tmux_saved_sessions

After reboot:

bashCopyEditwhile read session; do tmux attach-session -t "$session"; done < ~/.tmux_saved_sessions

---

💡 Best Workflow

1. Detach tmux (Ctrl + B, D) instead of closing it.

2. Use tmux-resurrect for auto-saving and restoring.

3. If rebooting often, use tmuxinator for structured sessions.
