先做一個實驗
創建一個死循環小程序
[zl@localhost test]$ pwd
/home/zl/test
[zl@localhost test]$ vi test.c
#include <stdio.h>
int main(int argc, char *argv[])
{
while (1){
sleep(1);
}
return 0;
}
[zl@localhost test]$ gcc test.c -o testc
[zl@localhost test]$ ./testc
這時打開另外一個窗口
[root@localhost zl]# ls /proc/3313/ -l
total 0
dr-xr-xr-x 2 zl zl 0 Jan 12 11:47 attr
-r-------- 1 zl zl 0 Jan 12 11:47 auxv

dr-xr-xr-x 3 zl zl 0 Jan 12 11:47 task
-r--r--r-- 1 zl zl 0 Jan 12 11:47 wchan
如果換一個目錄執行呢？
[zl@localhost test]$ cd ..
[zl@localhost ~]$ pwd
/home/zl
[zl@localhost ~]$ ./test/testc
[root@localhost zl]# ps -aux | grep test
