在我的Solaris 10 update 9系统上,以下命令产生:

#isainfo -b
64 

但是,如果我在C中使用limits.h创建以下程序,我会得到:

#include <stdio.h>
#include <limits.h>

int main(void)
{ 
     printf("Maximum integer value on this system is = %d\n", INT_MAX);
}

gcc on64.c -o on64
./on64

Maximum integer value on this system is = 2147483647

我期待更大的结果,因为系统运行在64位.这似乎是一个32位的结果.这是编译器问题吗？

伙计们,

我有一个包含ldap条目的文件,我想删除第二次出现的"version:1"行.我知道sed可以做这样的事情,但由于我很新,我不知道如何继续.这是Solaris 10计算机,文件如下所示:
