ubuntu18设置开机自启动

        项目需求：机器人开机上电后工控机首先运行机械臂控制代码，再运行算法代码

1.终端执行以下代码

gnome-session-properties

2.设置开机自启动选项

        在弹出界面点击添加，名称随便填，命令填入要启动的脚本，注释随便填。

gnome-terminal -- /home/txz/start.sh

3.开机自启动脚本start.sh

        开机后首先ping机械臂的ip地址，每隔5s ping一次，能ping通后执行机械臂蜷缩操作命令，然后再打开一个终端窗口，启动算法代码。

#!/bin/bash 
echo "$(date "+%Y-%m-%d %H:%M:%S") ceshila" >> /home/txz/screen.log
while true;do
    if ping -c 1 10.7.5.18 &> /dev/null;then
	echo "$(date "+%Y-%m-%d %H:%M:%S") Ping successul. Starting Python script."
    echo "$(date "+%Y-%m-%d %H:%M:%S") Ping successful. Starting Python script." >> /home/txz/screen1.log
    python3 /home/txz/arm_server/quansuo_position.py
	sleep 3
	python3 /home/txz/arm_server/quansuo_position.py
	sleep 1
	gnome-terminal -- /home/txz/8.17/401_serch-tcp_4/1_main_frame/build/test_demo
	sleep 1
	python3 /home/txz/arm_server/server_nano.py
	break
    else
	echo "$(date "+%Y-%m-%d %H:%M:%S") Ping unsuccessful.Retrying in 5 seconds."
	echo "$(date "+%Y-%m-%d %H:%M:%S") Ping unsuccessful.Retrying in 5 seconds." >> /home/txz/screen2.log
	sleep 5
    fi
done

 4.关机前操作代码stop.sh

        找到开机启动的代码命令，然后kill掉，再让机械臂恢复零位

#!/bin/bash

# 查询命令的ID
command_name="python3"  # 替换为你要查询的命令名称
command_pid=$(pgrep "$command_name")

if [ -z "$command_pid" ]; then
    echo "未找到运行的命令: $command_name"
else
    echo "找到运行的命令: $command_name (PID: $command_pid)"
    # 杀死命令
    kill -9 "$command_pid"
    echo "已杀死命令: $command_name (PID: $command_pid)"
fi
python3 /home/txz/arm_server/zero_position.py
sleep 3 
python3 /home/txz/arm_server/zero_position.py
