tmux - multi window session for linux

Tmux is very handy when working with linux

You can create session disconnect from server and then reconnect to this same session 

To easier manage session I wrote simple script which display list of available sesssions 

#!/bin/bash

# Function to display sessions and handle selection
select_tmux_session() {
    # Get list of tmux sessions and sort alphabetically
    sessions=$(tmux ls 2>/dev/null | cut -d: -f1 | sort)
    
    # Check if tmux is running and has sessions
    if [ $? -ne 0 ] || [ -z "$sessions" ]; then
        echo "No tmux sessions found or tmux server not running."
        echo "0 - Create new session"
        read -p "Enter your choice: " choice
        if [ "$choice" = "0" ]; then
            read -p "Enter new session name: " session_name
            if [ -n "$session_name" ]; then
                tmux new-session -s "$session_name"
            else
                echo "Session name cannot be empty."
            fi
        fi
        return
    fi
    
    # Display available sessions
    echo "Available tmux sessions:"
    echo "======================="
    
    # Convert sessions to array and display with numbers
    session_array=()
    counter=1
    
    while IFS= read -r session; do
        echo "$counter - $session"
        session_array+=("$session")
        ((counter++))
    done <<< "$sessions"
    
    echo "0 - Create new session"
    echo "======================="
    
    # Get user selection
    read -p "Enter your choice (0-$((counter-1))): " choice
    
    # Validate input
    if ! [[ "$choice" =~ ^[0-9]+$ ]]; then
        echo "Invalid input. Please enter a number."
        return 1
    fi
    
    # Handle selection
    if [ "$choice" = "0" ]; then
        # Create new session
        read -p "Enter new session name: " session_name
        if [ -n "$session_name" ]; then
            tmux new-session -s "$session_name"
        else
            echo "Session name cannot be empty."
        fi
    elif [ "$choice" -ge 1 ] && [ "$choice" -le "${#session_array[@]}" ]; then
        # Attach to selected session
        selected_session="${session_array[$((choice-1))]}"
        echo "Attaching to session: $selected_session"
        tmux attach -t "$selected_session"
    else
        echo "Invalid choice. Please select a number between 0 and $((counter-1))."
        return 1
    fi
}

# Run the function
