编程中经常需要在程序中使用shell命令来简化程序，这里记录一下。

1. C++ 执行shell命令

1 #include 
      
        2 #include 
       
         3 #include 
        
          4 5 int exec_cmd(std::string cmd, std::string &res){ 6 if (cmd.size() == 0){ //cmd is empty 7 return -1; 8 } 9 10 char buffer[1024] = { 0}; 11 std::string result = ""; 12 FILE *pin = popen(cmd.c_str(), "r"); 13 if (!pin) { //popen failed 14 return -1; 15 } 16 17 res.clear(); 18 while(!feof(pin)){ 19 if(fgets(buffer, sizeof(buffer), pin) != NULL){ 20 result += buffer; 21 } 22 } 23 24 res = result; 25 return pclose(pin); //-1:pclose failed; else shell ret 26 } 27 28 int main(){ 29 std::string cmd = "ls -ial"; 30 std::string res; 31 32 std::cout << "ret = " << exec_cmd(cmd, res) << std::endl; 33 std::cout << res << std::endl; 34 35 return 0; 36 }
        
       
      

2. Php执行shell命令

3. Python执行shell命令

1 import commands2 3 status, output = commands.getstatusoutput('ls -lt') 4 5 print status 6 print output
