意外令牌fork（）附近的语法错误

Question

#include <stdio.h>
#include <unistd.h>
main() 
{ 

    int some_value;

    printf("Forking process\n");

    fork();

    /* This part of the program is executed by two different proceses */
    printf("The process id is %d \n", getpid());
    some_value = getpid() + 10;
    printf("Some value is %d ", some_value);

    execl("/bin/ls","/bin/ls","-l",NULL);

    /* This line is not executed because of th execl function */
    printf("This line is not printed\n");
}  

对于这段代码，我收到以下错误：

./fork1.c: line 8: syntax error near unexpected token `"Forking process\n"'
./fork1.c: line 8: ` printf("Forking process\n");'

虽然我觉得这不是一个语法错误。

这不是一个shell脚本，它是C。

你必须编译它（例如：用gcc）然后运行创建的可执行文件。
