linux C 调用shell程序执行

#include<stdio.h>
#include <unistd.h>
#include <sys/types.h>
#include <stdlib.h>
#include <sys/prctl.h>
#include <signal.h>

int main()
{
pid_t pid;
char *cmd="bash testshell.sh";
//FILE *fResult=popen("/bin/bash -c testbash.sh","r");
//fResult.close();
pid=fork();
if(pid>)
        exit();
else if(pid==)
{

        //prctl(PR_SET_PDEATHSIG,SIGKILL);
        execl("/bin/bash","/bin/bash","-c",cmd,NULL);
        exit();
}
else if(pid<)
{
        printf("create faild\n");
        exit();
}
return ;
}

testshell.sh文件

date>testshell_log.log
echo "----------------------------">>testshell_log.log
java -jar TestOracle.jar>>testshell_log.log
echo "----------------------------">>testshell_log.log
date>>testshell_log.log>>testshell_log.log

在shell文件中可以执行各种linux命令，也可以写 if else fi 语句
