一道题目说的是有两个脚本,第一个脚本是script1:\r\n#!/bin/ksh\r\nvar1=\"dog\"\r\nvar2=\"cat\"\r\nexport var1\r\nexport var2 var1=\"mouse\"\r\n/usr/local/bin/script2\r\n第二个脚本是script2:\r\n#!/bin/ksh\r\nvar2=\"fish\"\r\necho \"${var1} ${var2}\"\r\n它的结果应该是什么:\r\na.dog cat\r\nb.dog fish\r\nc.mouse cat\r\nd.mouse fish\r\n答案是b,但是我在机器上面运行的结果却是d.会不会答案错了啊\r\n\r\n还有一题\r\n脚本/tmp/script1内容是:\r\n#!/usr/bin/ksh\r\nvar1=red\r\nexport var1=green\r\nvar1=blue\r\n/tmp/script2\r\nvar1=yellow\r\n脚本/tmp/script2内容是:\r\n#!/bin/ksh\r\necho \"the sky is ${var1}.\"\r\n输入内容应该是:\r\na. THe sky is red.\r\nb.THe sky is blue.\r\nc.THe sky is  green.\r\nd.THe sky is yellow.\r\n我运行的结果是b,可惜答案是a,这两道题麻烦大家分析一些谢谢啦
