1.C++实现

下面是封装好的C++头文件，直接调用run_cmd_fun()即可。

#ifndef GET_CMD_H
#define GET_CMD_H#endif // GET_CMD_H
#include <iostream>
#include<QString>
using namespace std;//system("gnome-terminal --window -e 'bash -c \"pwd;ls;exec bash\"' --tab -e 'bash -c \"pwd; exec bash\"'");
QString win_cmd = "gnome-terminal --window -e 'bash -c \"";  // 运行窗口的命令
QString tab_cmd = " --tab -e 'bash -c \""; //运行标签的命令
QString pause_cmd = ";exec bash\"'";  //终端等待的命令
QString source_path = "source /opt/ros/noetic/setup.bash ;"; //添加环境变量
QString Qcmd = "";void run_cmd_fun(QString cmd1)
{ //get one cmdQcmd = "";Qcmd.append(win_cmd);Qcmd.append(source_path);Qcmd.append(cmd1);Qcmd.append(pause_cmd);string cmd = Qcmd.toStdString();cout << cmd << endl;system(cmd.c_str());
}void run_cmd_fun(QString cmd1, QString cmd2, int input_time=1)
{ //get two cmd//The time setQcmd = "";QString pause_t = "sleep ";pause_t.append(QString::number(input_time));pause_t.append(";");//The  first cmd setQcmd.append(win_cmd);Qcmd.append(cmd1);Qcmd.append(pause_cmd);//The  second cmd setQcmd.append(tab_cmd);Qcmd.append(pause_t);Qcmd.append(cmd2);Qcmd.append(pause_cmd);//The  cm1 + cm2 --> string cmdstring cmd = Qcmd.toStdString();system(cmd.c_str());
}void run_cmd_fun(QString cmd1, QString cmd2, QString cmd3, int input_time=1)
{ //get three cmdQcmd = "";QString pause_t = "sleep ";pause_t.append(QString::number(input_time));pause_t.append(";");//The  first cmd setQcmd.append(win_cmd);Qcmd.append(cmd1);Qcmd.append(pause_cmd);//The  second cmd setQcmd.append(tab_cmd);Qcmd.append(pause_t);Qcmd.append(cmd2);Qcmd.append(pause_cmd);//The  third cmd setQcmd.append(tab_cmd);Qcmd.append(pause_t);Qcmd.append(pause_t);Qcmd.append(cmd3);Qcmd.append(pause_cmd);//The  cmd1 + cmd2 + cmd3 --> cmdstring cmd = Qcmd.toStdString();system(cmd.c_str());
}void run_cmd_fun(QString cmd1, QString cmd2, QString cmd3, QString cmd4, int input_time=1)
{ //get four cmdQcmd = "";//The time setQString pause_t = "sleep ";pause_t.append(QString::number(input_time));pause_t.append(";");//The first cmd setQcmd.append(win_cmd);Qcmd.append(cmd1);Qcmd.append(pause_cmd);//The second cmd setQcmd.append(tab_cmd);Qcmd.append(pause_t);Qcmd.append(cmd2);Qcmd.append(pause_cmd);//The third cmd setQcmd.append(tab_cmd);Qcmd.append(pause_t);Qcmd.append(pause_t);Qcmd.append(cmd3);Qcmd.append(pause_cmd);//The fourth cmd setQcmd.append(tab_cmd);Qcmd.append(pause_t);Qcmd.append(pause_t);Qcmd.append(pause_t);Qcmd.append(cmd4);Qcmd.append(pause_cmd);// cmd1 + cmd2 + cmd3 + cmd4 = cmdstring cmd = Qcmd.toStdString();system(cmd.c_str());
}

注意:想要生成双击直接运行的程序，需要添加：

QMAKE_LFLAGS += -no-pie

补充切换不同页面；

ui->stackedWidget->setCurrentIndex(3);

2.python实现

直接调用：run_cmd([“roscore”,“rostopic list”], 2)

openvino_path = "source /opt/intel/openvino/bin/setupvars.sh;"  # 添加的一些虚拟环境
ros_path = "source ~/.bashrc;"+openvino_path win_cmd = "gnome-terminal --window -e 'bash -c \""+ros_path
tab_cmd = " --tab -e 'bash -c \""+ros_path
end_cmd = ";exec bash\"'"def run_win(cmd):# 运行的第一个窗口终端cmd = win_cmd+cmd+end_cmdreturn cmddef run_tab(cmd, t):# 运行的标签终端delay_t = "sleep {};".format(str(t))cmd = tab_cmd+delay_t+cmd+end_cmdreturn cmddef run_cmd(cmds, t = 2):cmd  = run_win(cmds[0])for i in range(1, len(cmds)):cmd = cmd + run_tab(cmds[i], t*i)print(cmd)os.system(cmd)
